New error correction approach simplifies quantum computing – Inceptive Mind

L3Harris successfully completed its Critical Design Review (CDR) and Production Readiness Review (PRR) for 16 missile tracking satellites that will be part of the Space Development Agencys (SDA) Tranche 1 Tracking Layer (T1TRK) program.

Hypersonic missiles pose a serious threat to global stability and security because they are hard to detect, track, and intercept. They can be launched from various locations and can change direction rapidly during flight. To deter their use and, when needed, to defeat them, the United States requires a resilient sensor platform to track their movements and ensure the countrys national security.

The recent CDR and PRR milestones achieved by L3Harris demonstrate progress towards SDAs Proliferated Warfighter Space Architecture, which aims to establish a network of military satellites in low-Earth orbit to provide enhanced situational awareness and tracking capabilities. The CDR milestone demonstrates that L3Harris design will meet the mission requirements, while the PRR provides L3Harris with the SDAs approval to begin the full production process.

The Tranche 1 Tracking Layer developed by L3Harris relies on infrared sensors and advanced algorithms to detect, track, and fuse threat data. The information is then relayed in real-time to the warfighter through a meshed network that employs both optical and RF communications.

In addition, the space vehicles can be commanded from the ground to a range of pointing modes that provide further insight into threat tracks. L3Harris also provides supporting ground, operations, and sustainment throughout the lifespan of the program.

L3Harris is working hard to meet launch schedule commitments for their missile-tracking satellites. They started fabrication of critical sub-assemblies before the CDR and PRR and have successfully transitioned to the assembly and integration phase. Theyre working with over 20 major subcontractors and dozens of suppliers to provide critical parts for the satellites and ground systems.

The satellites are slated for launch in 2025 and will feature advanced technology designed to counter the fastest, most maneuverable hypersonic missiles.

L3Harris is working in lockstep with the SDA to get these critical capabilities on-orbit and into the hands of the nations warfighters as quickly as possible, L3Harris Director of Program Management Bob De Cort said in the statement. The SDA takes a fundamentally fresh and different approach than traditional defense contracting. Rather than investing schedule and funds in single point solutions, the SDA acquisition plan breaks from tradition to use spiral development leveraging interoperable commercial technologies to deploy tranches of satellites every couple of years.

De Cort continued, Our recent success at CDR and PRR show that we are the leading partner within SDAs Proliferated Warfighter Space Architecture, demonstrating not just missile warning and tracking but the beyond line of sight targeting that the warfighters need to enhance Americas strategic deterrence from space.

Unexpected Pairing Paves the Way for Computing Devices – AZoQuantum

Researchers at EPFL make significant advances in quantum physics by exposing a peculiar and enigmatic behavior in a quantum magnetic material and providing hints about potential future technological developments.

The world of quantum materials is a mysterious place where things do not always behave as expected. These materials can perform tasks in ways that traditional materials cannot, such as conducting electricity without loss or having magnetic properties that may prove useful in advanced technologies. These unique properties are governed by the laws of quantum mechanics.

Certain quantum materials have minute magnetic waves, known as magnons, circulating through them. These waves exhibit peculiar behaviors. Gaining an understanding of magnons is essential for deciphering the microscopic workings of magnets, which will be important for the development of next-generation computers and electronics.

Up until recently, researchers believed they understood what to expect from the studies of these magnons behavior in strong magnetic fields. Researchers at EPFL, led by Henrik Rnnow and Frdric Mila, have revealed a new and unexpected behavior in strontium copper borate (SrCu2(BO3)2), a quantum material. Although the study casts doubt on what is already known about quantum physics, it also raises intriguing possibilities for next-generation technologies.

But why this particular content? SrCu2(BO3)2 is significant in the field of quantum materials, though the specifics are highly technical. This is because it is the only known real-world example of the Shastry-Sutherland model, a theoretical framework for comprehending structures where atoms' interactions and arrangement prevent them from settling into a simple, ordered state.

Known as highly frustrated lattices, these structures frequently endow the quantum material with complex, peculiar behaviors and characteristics. Therefore, SrCu2(BO3)2 is a perfect candidate to study intricate quantum phenomena and transitions due to its unique structure.

Neutron scattering is a method that the scientists used to study the magnons in SrCu2(BO3)2. In essence, they exposed the material to neutrons and measured how many of them deflected off of it. Since neutrons have no charge and can therefore analyze magnetism without being affected by the charge of the materials electrons or nuclei, neutron scattering is especially useful in the study of magnetic materials.

This work was done at the Helmholtz-Zentrum Berlin's high-field neutron scattering facility, which could probe fields as high as 25.9 Tesla. This level of magnetic field study was unprecedented and allowed the scientists to see the behavior of the magnons up close.

Subsequently, the scientists integrated the data with cylinder matrix-product-states computations, an effective computational technique that supported the experimental findings from the neutron scattering and clarified the two-dimensional quantum behaviors of the material.

The novel method disclosed a startling finding: the material's magnons were forming bound states, or pairing up to dance, rather than acting as single, independent unities as would have been predicted.

The spin-nematic phase, a novel and unexpected quantum state with ramifications for the materials properties, is the result of this peculiar pairing. Imagine it like this: unlike regular magnets on a fridge, which point either way (that is their spin), the focus of this new phase is on how the magnets align with one another to form a distinctive pattern rather than on their direction of orientation.

This is a fascinating finding. It exposes a previously unseen behavior in magnetic materials. This discovery of a hidden law of quantum mechanics may open our minds to previously unconsidered uses of magnetic materials in quantum technologies.

The research was funded by the European Research Council (ERC) Synergy network HERO, the

Swiss National Science Foundation (SNSF), and the Qatar Foundation.

Quantum technology professor Pepijn Pinkse: The best time to get quantum security right was yesterday. – Innovation Origins

His inaugural lecture took place early last month; in practice, Pepijn Pinkse has been working as a professor of quantum technology at the University of Twente (UT) for several years. His lecture focused on creating awareness around quantum security and the threat posed by quantum technology. The best time to get quantum security right was yesterday, he said.

Quantum security is crucial to the future of privacy and data security. Professor Pepijn Pinkse, a pioneer at the University of Twente, is developing groundbreaking methods to secure data in an unbreakable way. Twente leads the world when it comes to quantum technology.

See this laser beam? Its a neat bundle of light waves falling in line. Pinkse holds an A4 sheet in front of the camera on which he shines a laser pointer. If I put a piece of tape on the laser, you can see that a complex pattern of speckles forms in the light. As soon as you add five photons to that pattern, they distribute themselves among the speckles. We use the combination of quantum light light with a small number of photons and a complex pattern to read out a key.

Or, in other words, Pinkse has developed a key that cannot be copied, even when someone has all the information. The key is verified by shining a light pulse on it with fewer photons (light particles) than there are spatial degrees of freedom (speckles). The professors contribution was instrumental in inventing this Quantum-Secure Authentication method, which was largely developed in Twente.

Developing authentication methods is so important because the advent of quantum computers poses risks to data security. Once quantum computers are powerful and reliable enough, most current cryptographic security methods of the Internet and data files will be vulnerable overnight.

Quantum computers operate on a different principle than classical computers. The main difference is the fundamental unit of information, or bit. The conventional digital bit knows no more than two states 0 or 1 and thus performs calculations incrementally. The information unit of a quantum computer qubit can be in both states simultaneously. This condition is referred to as superposition. Because of this parallel mode of operation, the computation time on a quantum computer grows much less rapidly with the size of the problem, and in the future, they can solve complex tasks that are too difficult for classical computers, Pinkse explains.

Pinkse studied physics at Leiden University and received his doctorate from the University of Amsterdam. He spent ten years at the renowned Max-Planck Institute for Quantum Optics. In 2009, he transferred to UT, where he did pioneering work on quantum secure authentication. He received a Vici grant, the Dutch Research Councils (NWO) highest personal grant, for his research in 2013. Since 2019, Pinkse has been a professor of Adaptive Quantum Optics. He is also the director of the center for Quantum NanoTechnology Twente (QUANT) and co-founder of spin-off Quix-Qantum.

Most of our current cryptography, think of Internet banking, for example, is based on the fact that you can easily multiply two large prime numbers together, Pinkse explains. Making the sum the other way around is difficult.

Prime numbers are divisible only by 1 and themselves, such as 7, 11, or 61; numbers like 6 and 15 are not. Consider the following calculation: 71 x 61 = 4331. Determining which multiplication 4331 is the result is much more difficult because you have to try numerous options.

Pinkse: The Shor algorithm can make that reverse computation efficiently, although it needs a large and good universal quantum computer to do so. As a result, much of our encrypted data is no longer secure.

This is not yet the case, as quantum computers currently have a small number of memory elements (qubits) and are noisy. The professor expects that it will be about ten years before Q-day the day when current cryptographic security systems succumb to the pressure of quantum computers happens. But that doesnt mean we shouldnt take action now, Pinkse warns. If in ten years there is a working universal quantum computer that can decipher eavesdropped messages from today, we need to start protecting against it now with encryption techniques that cannot be broken even then.

Quantum technology has long been used in semiconductors, lasers, and MRI scanners. Even smartphones and the Internet would not exist without this technology. However, these applications do not (yet) use quantum information based on specific properties of quantum particles, such as entanglement. Applications Pinkse talks about in this article aka Quantum Technology 2.0 do.

Besides the risks involved in this elusive technology, the potential is huge. Pinske: Quantum computers can help us understand chemical reactions much better and be able to make smarter batteries and more effective medicines. Quantum is a key technology for the energy transition and health care.

The first universal prototype of a quantum computer might come out of Twente. At UT spin-off Quix Quantum, of which Pinkse is a co-founder they are developing a universal quantum computer. The company hopes to have the prototype ready in three years; the computer has already been sold to the German center for aerospace. Twentes quantum computer runs on light and is leading the way in Europe. Pinkse: The American competitor PsiQuantum has raised hundreds of millions in investments but has not sold anything yet.

Whereas commerce was often a dirty word in the early years of his career, at UT, it is anything but such. At many institutes and universities, commerce is an afterthought that distracts from the science itself. Here, the emphasis is very much on the contribution you can make to society through your research. That makes my work incredibly fun.

What is IBM doing in the race towards quantum computing? – TechHQ

Quantum computing uses electrons rather than transistors, for a much more rapid solution to complex problems. Theres every likelihood that the technology will be able to rapidly reduce current encryptions to dust. The quantum race is largely between China and a handful of western companies.

We may be on the verge of revolutionary AI problem-solving with news of IBMs quantum computing advancements. (We say may in tribute to Werner Heisenberg and his famous principle, and because nothing since has ever been entirely certain in the quantum world).

We are living in a golden age of artificial intelligence, with innovations seemingly bombarding us every day. The trend has continued with IBM announcing advancements in a new kind of computing that is capable of solving extraordinarily complex problems in just a few minutes.

Why is this newsworthy? Surely thats what all computers do?

Yes, but todays supercomputers would need millions of years to solve problems as complex as the ones IBM is making progress with.

Welcome to the wonderful world of quantum.

Quantum computing is a technology being developed by companies like IBM and Google. Operating in a fundamentally different way to classical computing, it relies on quantum bits (qubits) and principles including superposition and entanglement. As the name suggests, quantum physics is an intrinsic part of quantum computing. We may even need a quantum computer to explain how this type of computing works, but this technology is without question changing the world.

Everything we know is pushed to the limits with quantum computing. From science to finances and from AI to computational power, this supercomputer offers the potential for solutions to problems that are currently intractable for classical computers.

The revolutionary nature of quantum computing lies in its potential to transform problem-solving approaches. It has the potential to tackle previously unsolvable problems, and impact many fields worldwide. It presents a paradigm shift akin to the introduction of classical computing, though in comparison, quantum computings possibilities are on a vastly different and exponentially more powerful scale.

IBM director of research Dario Gill believes quantum computing will have a significant impact on the world, but that society is not yet prepared for such changes.

It feels to us like the pioneers of the 1940s and 50s that were building the first digital computers, he said. Its plain to see how much impact digital computers have had on the world since the 1950s, but quantum computing is another kettle of deeply unusual fish.

We are now at a stage where we can do certain calculations with these systems that would take the biggest supercomputers in the world to do, Gill explained. But the potential of this technology is only just being realized. The goal is to continue the expansion of quantum computing capabilities, so that not even a million or a billion of those supercomputers connected together could do the calculations of these future machines.

A quantum computer from IBM the future appears to be agreeably steampunk.

We have already witnessed significant progress in this field of technology, but the difference now is that Dario Gill, and others working in the quantum field, have a clear plan or strategy in place for further advancements. That means the rate of progress is only expected to accelerate possibly at a pace that will surprise the world.

Today, computers process information on transistors, something they have done since the advent of the transistor switch in 1947. Over time, however, the speed and capabilities of computers have increased substantially. This is due to the continuous advancement of technology. This enhancement stems from the strategy of densely integrating an increasing number of transistors onto a single chip, reaching a scale of billions of transistors in todays computer chips.

Computers require billions of transistors because they are in either an on or off state. Known as complementary metal-oxide-semiconductor (CMOS) technology, quantum computing is now presenting alternatives to this hallmark of classic computing.

Rather than using transistors, quantum computing encodes information and data on electrons. These particles, thanks to the rules of quantum mechanics, can exist in multiple states simultaneously, much like a coin spinning in the air. Simultaneously, it shows aspects of both heads and tails. Unlike traditional computing methods, that deal with one bit of data at a time on a transistor, quantum computing uses qubits. These can store and process exponentially more information because of their ability to exist in multiple states at once.

Classical computers require a step-by-step process when finding information or solving problems. Quantum computers, on the other hand, are capable of finding solutions much faster by handling numerous possibilities concurrently.

Like any up-and-coming technology, countries around the world are vying for quantum supremacy. Currently, private free enterprises and state-directed communism are the main competitors. In other words, the race is between China on one side, and IBM, Google, Microsoft, [and] Honeywell, according to physicist Michio Kaku. These are the big boys of quantum computing.

America has approximately 180 private firms researching quantum computing, most of which fund themselves. The US also has a number of government initiatives investing heavily in quantum research. Along with IBM, Google, and Microsoft, institutions including NASA, DARPA, and NIST are at the forefront of quantum computing and technology development.

Quantum computing bringing the sci-fi home.

China has been making substantial investments in quantum development and research for a number of years. For instance, it has several state-backed initiatives and research institutions, including the Chinese Academy of Sciences, all working on quantum technology. Large corporations, including Alibaba and Huawei, are also involved in quantum computing research.

The US government currently spends close to $1 billion a year on quantum research, whereas China has named quantum as a top national priority. New standards for encryption are to be published by the US in 2024, something that will cause waves (or potentially particles) in the quantum field.

If youre looking for revolutions in computing as big as quantum, youre probably looking back to the machine that cracked the Enigma code

The winner of this quantum race will have striking implications, as Kaku believes the nation or company that succeeds will rule the world economy.

Think OpenAI and ChatGPT, but with the potential to crack any code, open any safe, and of course, demand any price.

As we immerse ourselves in quantum computings promising possibilities and how it is a savior to all of humanitys problems, we must not forget the challenges it also faces. For instance, coherence times need to be enhanced and machines require scaling up to operate effectively with quantum computing.

Hartmut Neven, founder and manager of Googles Quantum Artificial Intelligence Lab, believes that small improvements and effective integration of existing pieces are key to building larger quantum systems. We need little improvements here and there. If we have all the pieces together, we just need to integrate them well to build larger and larger systems.

Neven and his team aim to achieve significant progress in quantum computing over the next five or six years. He believes that quantum computing holds the key to solving problems in fields like chemistry, physics, medicine, and engineering that classical computers are currently, and will always, be incapable of. You actually require a different way to represent information and process information. Thats what quantum gives you, he explained.

Further challenges persist due to the delicate nature of qubits, which are prone to errors and interference from the surrounding environment. As James Tyrrell discusses here, efforts to mitigate this noise and enhance the reliability of quantum computers are underway. The expansion of the (Quantum-Computing-as-a-Service) QCaaS ecosystem is expected to shift the focus from technical intricacies to practical applications. This will potentially allow users to harness the power of quantum computing for real-world problem-solving.

The development of quantum computing is accelerating at an exponential rate. Over the next decade or so, Dario Gil sees no reason why quantum computing can expand to thousands of qubits. He believes that systems will be built that will have tens of thousands and even a 100 thousand qubits working with each other. Where quantum technology goes from here is (thank you, Werner!) distinctly uncertain, but if the excitement is anything to go by, it may potentially have the answers to all the worlds problems.
