Will Quantum Mechanics Produce the True Thinking Computer? – Walter Bradley Center for Natural and Artificial Intelligence

Some hope that quantum mechanics can explain human consciousness.

Maybe we are all quantum computers but dont know it? Maybe quantum computers could think like people?

There is an odd relationship between the human mind and quantum mechanics, the science of entities like electrons that are too small to be governed by ordinary physics.

Some aspects of consciousness appear to be mediated by such elementary particles. Science writer Philip Ball explains,

Nobody understands what consciousness is or how it works. Nobody understands quantum mechanics either. Could that be more than coincidence?

Quantum mechanics is the best theory we have for describing the world at the nuts-and-bolts level of atoms and subatomic particles. Perhaps the most renowned of its mysteries is the fact that the outcome of a quantum experiment can change depending on whether or not we choose to measure some property of the particles involved

To this day, physicists do not agree on the best way to interpret these quantum experiments, and to some extent what you make of them is (at the moment) up to you. But one way or another, it is hard to avoid the implication that consciousness and quantum mechanics are somehow linked.

This might, of course, be at least one part of the reason that consciousness remains a mystery.

But now, is a quantum computer smarter than the conventional machine that just computes numbers?

In Gaming AI, tech philosopher George Gilder notes that the resourceful AI geniuses believe that they can effect an astronomical speedup by changing the ordinary 1 or 0 bit to the quantum bit, or qubit:

The qubit is one of the most enigmatic tangles of matter and ghost in the entire armament of physics. Like a binary digit, it can register 0 or 1; what makes it quantum is that it can also register a nonbinary superposition of 0 and 1.

But before we get carried away by the possibilities, Gilder goes on to say that theres a hitch. An endless superposition works fine for Schrodingers cat. But, to be useful in the real world, the quantum computer must settle on either 0 or 1. If the needed number is your paycheck, to be cashed, it must be a number, not an infinite debate.

In any event, quantum computers come with real world problems that conventional computers dont have:

the chip can no longer function as a determinist logical device. For example, today the key problem in microchips is to avoid spontaneous quantum tunneling, where electrons can find themselves on the other side of a barrier that by the laws of classical physics would have been insurmountable and impenetrable. In digital memory chips or processors, spontaneous tunneling can mean leakage and loss.

Quantum computing has advantages and disadvantages. In any event, consciousness is still a mystery and its not clear at this point how quantum computers help us understand much. But stay tuned!

Strategic Partnership will aid smooth work in the event of regional crisis: Australia High Commissioner – The Hindu

Artificial Intelligence, 5G, rare earth products, ground station tracking facilities to support Gaganyaan are among the areas covered, says Barry OFarell

Australian High Commissioner to India Barry OFarrell took charge a month before the COVID-19 pandemic struck in India, yet his time here has seen a steady uptick in the momentum of bilateral cooperation including a Prime Ministerial summit in June and, more recently, Australias inclusion in the Malabar naval exercises. He speaks toNarayan Lakshman about a range of cooperative initiatives on the anvil.

It will demonstrate the ability of our navy to work through exercises, warfare serials and like with the navies of India, Australia, the U.S. and Japan. That is important because, were there to be a regional crisis, like a natural or humanitarian disaster, the ability to work smoothly with partners is critical. It builds particularly on the maritime agreement that was one of the agreements underneath the CSP, but also to the mutual logistic support arrangement, which is designed to improve the collaboration between our armed forces. This reflects the commitment that Quad partners have to a free, open, and prosperous Indo Pacific. It demonstrates the commitment that Australia and India have to what Prime Minister Modi described at the June summit as a sacred duty to provide the neighbourhood with the environment where people could prosper, where there could be stability upon which to build your lives, and where you could live freely. It reiterates that.

It also comes off the back of ongoing interactions between our armed forces. To some extent, Malabar was a fixation that we are delighted to be part of, but it was a fixation because it ignored the fact that the AusIndex exercise last year was the largest naval engagement Australia had ever been a part of, and most complex involving submarine serials and P-8 Poseidon maritime patrols across the Bay of Bengal. Equally, the recent passage exercise again demonstrated our ability to work together, including practising warfare serials on water. All these things increase the level of cooperation, increase the significance of the relationship, but practically ensure that should they be called upon, our navies could work more closely together, effectively, in support of a peaceful, stable and prosperous Indo Pacific.

Certainly, the COVID-19 pandemic has damaged economies. It has accelerated geostrategic competition, and it has obviously disrupted our way of life. It has highlighted the importance, to countries like India and Australia, of ensuring a safe, secure and prosperous future for our citizens. Thats why, as part of the CSP, there were agreements in relation to critical technologies such as Artificial Intelligence, quantum computing and 5G because we recognise the opportunities they present to people, to businesses, to the broader economy, and the fact that they should be guarded by international standards to ensure they do not present risks, to security or prosperity. The Australia-India framework Arrangements on Cyber and Cyber Enabled Critical Technology cooperation, abbreviated as the Arrangement, will enhance bilateral cooperation. Under the agreement, we are going to cooperate together to promote and preserve that open, free, safe and secure Internet by working around those international norms and rules that we talk about. It sets out practical ways to promote and enhance digital trade, harness critical technologies, and address cyber security challenges. It provides a programme of 66 crore over four years for an Australia-India cyber and critical technology partnership to support research by institutions in both Australia and between institutions in Australia and India. We also signed an MoU on critical minerals between both countries because they are the essential inputs into these critical and emerging technologies, which cover areas like high tech electronics, telecommunications, clean energy, transport and defence. Critical minerals are essential if India wants to achieve its energy mission goal in the battery industry, storage industry and electric vehicle industry.

Editorial | A new dimension: On India-U.S.-Australia-Japan Quadrilateral

If you want to build batteries or electric vehicles, lithium, amongst other items, is required. We know that your northern neighbour is your most significant supplier of these critical minerals. We know that India is seeking to become more self-reliant. We know that imports from China are reducing. Australia potentially sees an opportunity for us to provide elements into Indias efforts to improve its manufacturing, defence and electric vehicle and energy mission projects. We have Indian companies who are currently owning or significant investors in Australian critical minerals and rare earths companies. We have just released a new prospectus on critical minerals and rare earths which lists over 200 projects capable of attracting more investment into India.

I know theres concern in some parts of the community that self-reliance means protectionism. Well, we believe, firstly, that that is not the case, and that there will always be markets in India for elements that can be used by India to grow economies, grow businesses and provide more jobs and more wealth into society. But secondly, if you were concerned about the protectionist angle, the fact is that there is nothing stopping you coming to Australia to buy a mine to put those resources, those elements, into your own businesses, in the same way as is happening with coalfield in Queensland.

Firstly, Australia is already contributing to Indias national quantum mission by facilitating partnerships with universities, research institutions and businesses. That includes one of the best relationships we have with India, which is the Australian India Strategic Research Fund, which has been going for over 20 years. Since 2013, one of our Australians of the Year, Professor Michelle Simmons, has led a team of researchers at New South Wales Universitys (UNSW) Centre for Quantum Computation and Communication Technology, seeking to build the first quantum computer in silicon.

For quantum computers to be successful with their calculations, they have to be 100% accurate, but electrical interference called charge noise gets in the way. To tackle this problem, the UNSW has used a Research Fund from that Australia India Strategic Research Fund to collaborate with the Indian Institute of Science Bangalore, to combine Australias state of the art fabrication facilities, and Indias ultra-sensitive noise measurement apparatus. This has helped identify how and where the fabrication process should be adjusted. Earlier this year, the UNSW team was able to achieve a 99.99% accuracy in their atomic level silicon prototype. They believe it is only a matter of time before theyre able to demonstrate 100% reliability, and produce a 10 qubit prototype quantum integrated processor, hopefully by 2023. This has the potential to revolutionise virtually every industry, solving problems and processing information that would take a conventional computer millions of years to calculate in seconds. This is practical cooperation between the UNSW and the Institute in Bangalore, going on right now ready to hopefully come to practical fruition in 2023. Equally, in the upcoming Bengaluru Tech Summit we will host an exclusive session providing an overview of our innovative ecosystem, our cyber and critical technology capabilities, growing space ambitions, and the applications of computing, and quantum computing. Professor Simmons will be one of the keynote speakers. We recommend tuning into 11 a.m. on Friday November 20 for the session From Cyberspace to Outer Space: Innovating with Australia in a Post-COVID World. The bottom line is that India and Australia, through two respected institutions, are close to cracking something nowhere else in the world has been cracked, and it is likely to be ready within the next three years.

Firstly, we have a space sector going back to back to 1967. We launched our first rocket in South Australia and Woomera in 1967. But we were also critical to NASA throughout, regarding the use of space as part of NASAs global space infrastructure. We received those pictures from the first moon landing and broadcast them to the world. The U.S.s two systems failed and ours didnt fail on camera, and thats why we had pictures of Neil Armstrong walking on the moon. We have facilitated communication with deep space probes and also the landing craft on Mars.

Australia and India have been cooperating together as countries since 1987, when we inked our first MoU, and there is a strong engagement between ISRO and Australian agencies. We have undertaken data collaboration on Indian remote satellites. Since 2013, we have been doing laser ranging for Indian regional navigational satellite systems. We launched an Australian satellite by an Australian company and of course, we look forward to your manned space mission in 2022. We are exploring how we can place temporary ground station tracking facilities in Australia to support that Gaganyaan Mission. That is something that is practically under way as we speak. But we have been impressed by Indias capabilities and ambitions in space. You have the record for the most number of satellites released by a single rocket ever. It was more than 100 in 2017.

A lot of the universities are using the online option. As someone whos been coming to India for 10 years, initially I did notice a resistance to online education. Like the other technologies that were finally using during COVID, that resistance has been broken down. I confirmed that with the Director of the Indian Institute of Technology, IIT Madras. But we recognise that it is face-to-face learning, like face-to-face working, is still what most people want. A number of Australian States are starting pilot programmes to demonstrate that students can be picked up and returned to Australia into campuses safely given the COVID spread. And my Education Minister Dan Tehan made the point two weeks ago that the Australian government is keen for that to happen as soon as possible. The latest part to be announced was one from South Australia that will fly students out of Singapore into Australia. There was an early one announced by the Northern Territory. On the back of those, there is a hope that we will be able to return students to Australia for Day One, Term One, next year. But it will depend on those State trials. It is a bit like our approach to opening up bubbles with other countries: we would like to see things being done in situ, in practice, in real time to show that it can succeed. If the trials are successful, I remain confident about next year.

The challenge at the present time is that both countries have international flight bans. The only flights operating between both countries are repatriation flights. Malaysia and Singapore, which were the two countries in pre-COVID times where passengers could transit to get to Australia or to come to India, are not accepting Indian citizens. But that in no way undermines Australias desire to resume whatever is going to be business as usual, in relation to tertiary education.

Australian State governments and our education institutions themselves have put a lot of effort into looking after those Indian students who were stranded in Australia due to the COVID-19 crisis. Some of them are people that have had to wait a month or two until the Vande Bharat planes started. Having graduated mid-year, they have now hopefully most of them flying home, while others are still continuing their studies. Whilst, like many places at the start of COVID-19, there were a few teething problems, Im delighted to say a combination of State and federal governments and the universities and the Indian community there have been supportive of Indian students in Australia.

Reimagining the laser: new ideas from quantum theory could herald a revolution – The Conversation AU

Lasers were created 60 years ago this year, when three different laser devices were unveiled by independent laboratories in the United States. A few years later, one of these inventors called the unusual light sources a solution seeking a problem. Today, the laser has been applied to countless problems in science, medicine and everyday technologies, with a market of more than US$11 billion per year.

A crucial difference between lasers and traditional sources of light is the temporal coherence of the light beam, or just coherence. The coherence of a beam can be measured by a number C, which takes into account the fact light is both a wave and a particle.

Read more: Explainer: what is wave-particle duality

From even before lasers were created, physicists thought they knew exactly how coherent a laser could be. Now, two new studies (one by myself and colleagues in Australia, the other by a team of American physicists) have shown C can be much greater than was previously thought possible.

The coherence C is roughly the number of photons (particles of light) emitted consecutively into the beam with the same phase (all waving together). For typical lasers, C is very large. Billions of photons are emitted into the beam, all waving together.

This high degree of coherence is what makes lasers suitable for high-precision applications. For example, in many quantum computers, we will need a highly coherent beam of light at a specific frequency to control a large number of qubits over a long period of time. Future quantum computers may need light sources with even greater coherence.

Read more: Explainer: quantum computation and communication technology

Physicists have long thought the maximum possible coherence of a laser was governed by an iron rule known as the Schawlow-Townes limit. It is named after the two American physicists who derived it theoretically in 1958 and went on to win Nobel prizes for their laser research. They stated that the coherence C of the beam cannot be greater than the square of N, the number of energy-excitations inside the laser itself. (These excitations could be photons, or they could be atoms in an excited state, for example.)

Now, however, two theory papers have appeared that overturn the Schawlow-Townes limit by reimagining the laser. Basically, Schawlow and Townes made assumptions about how energy is added to the laser (gain) and how it is released to form the beam (loss).

The assumptions made sense at the time, and still apply to lasers built today, but they are not required by quantum mechanics. With the amazing advances that have occurred in quantum technology in the past decade or so, our imagination need not be limited by standard assumptions.

The first paper, published this week in Nature Physics, is by my group at Griffith University and a collaborator at Macquarie University. We introduced a new model, which differs from a standard laser in both gain and loss processes, for which the coherence C is as big as N to the fourth power.

In a laser containing as many photons as a regular laser, this would allow C to be much bigger than before. Moreover, we show a laser of this kind could in principle be built using the technology of superconducting qubits and circuits which is used in the currently most successful quantum computers.

Read more: Why are scientists so excited about a recently claimed quantum computing milestone?

The second paper, by a team at the University of Pittsburgh, has not yet been published in a peer-reviewed journal but recently appeared on the physics preprint archive. These authors use a somewhat different approach, and end up with a model in which C increases like N to the third power. This group also propose building their laser using superconducting devices.

It is important to note that, in both cases, the laser would not produce a beam of visible light, but rather microwaves. But, as the authors of this second paper note explicitly, this is exactly the type of source required for superconducting quantum computing.

The standard limit is that C is proportional to N , the Pittsburgh group achieved C proportional to N , and our model has C proportional to N . Could some other model achieve an even higher coherence?

No, at least not if the laser beam has the ideal coherence properties we expect from a laser beam. This is another of the results proven in our Nature Physics paper. Coherence proportional to the fourth power of the number of photons is the best that quantum mechanics allows, and we believe it is physically achievable.

An ultimate achievable limit that surpasses what is achievable with standard methods, is known as a Heisenberg limit. This is because it is related to Heisenbergs uncertainty principle.

Read more: Explainer: Heisenbergs Uncertainty Principle

A Heisenberg-limited laser, as we call it, would not be just a revolution in the design and performance of lasers. It also requires a fundamental rethinking of what a laser is: not restricted to the current kinds of devices, but any device which turns inputs with little coherence into an output of very high coherence.

It is the nature of revolutions that it is impossible to tell whether they will succeed when they begin. But if this one does, and standard lasers are supplanted by Heisenberg-limited lasers, at least in some applications, then these two papers will be remembered as the first shots.

Quantum Inspired Algorithm Going Back To The Source – Hackaday

Recently, [Jabrils] set out to accomplish a difficult task: porting a quantum-inspired algorithm to run on a (simulated) quantum computer. Algorithms are often inspired by all sorts of natural phenomena. For example, asolution to the traveling salesman problem models ants and their pheromone trails. Another famous example is neural nets, which are inspired by the neurons in your brain. However, attempting to run a machine learning algorithm on your neurons, even with the assistance of pen and paper would be a nearly impossible exercise.

The quantum-inspired algorithm in question is known as the wavefunction collapse function. In a nutshell, you have a cube of voxels, a graph of nodes, or simply a grid of tiles as well as a list of detailed rules to determine the state of a node or tile. At the start of the algorithm, each node or point is considered in a state of superposition, which means it is considered to be in every possible state. Looking at the list of rules, the algorithm then begins to collapse the states. Unlike a quantum computer, states of superposition is not an intrinsic part of a classic computer, so this solving must be done iteratively. In order to reduce possible conflicts and contradictions later down the line, the nodes with the least entropy (the smallest number of possible states) are solved first. At first, random states are assigned, with the changes propagating through the system. This process is continued until the waveform is ultimately collapsed to a stable state or a contradiction is reached.

Whats interesting is that the ruleset doesnt need to be coded, it can be inferred from an example. A classic use case of this algorithm is 2D pixel-art level design. By providing a small sample level, the algorithm churns and produces similar but wholly unique output. This makes it easy to provide thousands of unique and beautiful levels from an easy source image, however it comes at a price. Even a small level can take hours to fully collapse. In theory, a quantum computer should be able to do this much faster, since after all, it was the inspiration for this algorithm in the first place.

[Jabrils] spent weeks trying to get things running but ultimately didnt succeed. However, his efforts give us a peek into the world of quantum computing and this amazing algorithm. We look forward to hearing more about this project from [Jabrils] who is continuing to work on it in his spare time. Maybe give it a shot yourself by learning the basics of quantum computing for yourself.
