Scientists quantum entangle individual molecules for the first time – ZME Science

Credit: DALL-E 3.

Princeton physicists have successfully linked individual molecules into quantum mechanically entangled states. This groundbreaking feat allows molecules to remain interconnected across vast distances, a phenomenon often described as one of the most bizarre in quantum mechanics.

This linkage persists regardless of the physical distance between the molecules, embodying the concept of spooky action at a distance as once skeptically noted by Albert Einstein. Previously, only individual atoms and ions could be coaxed into this state.

The research, led by Assistant Professor Lawrence Cheuk and his team at Princeton University, marks a pivotal advancement in understanding quantum entanglement. Entanglement, a core principle of quantum mechanics, occurs when particles become so deeply connected that the state of one instantaneously influences the other, no matter the distance separating them.

Cheuk and his team envision entangled molecules as foundational elements for future technologies like quantum computers, capable of outperforming traditional computing in specific tasks. Additionally, quantum simulators and sensors, leveraging entanglement, promise advancements in modeling complex materials and enhanced measurement capabilities, respectively.

Computing devices based on quantum phenomena like entanglement are supposed to be orders of magnitude more powerful than conventional computers based on silicon transistors. Their edge or quantum advantage stems from the principles of superposition and quantum entanglement, where quantum bits, or qubits, can exist in multiple states simultaneously, unlike the binary states of classical computer bits.

However, achieving controllable quantum entanglement remains extremely challenging. Qubits are highly sensitive to noise and hold their quantum state typically for very short periods before losing coherence. As a result, the current state of the art is crippled by errors and todays quantum computers are unlikely to output correct answers even for relatively trivial programs for now.

This explains why the quantum computing landscape is rich in dozens of competing technologies. There are quantum computers that work with trapped ions, photons, and superconducting circuits just to name a few all vying for the billion-dollar breakthrough that might finally fulfill the industrys promise of taking computers to the next level.

Now, with this most recent advance, quantum computers that use molecular qubits can be added to this growing list of experimental technologies.

What this means, in practical terms, is that there are new ways of storing and processing quantum information, said Yukai Lu, a graduate student in electrical and computer engineering and a co-author of the paper.

For example, a molecule can vibrate and rotate in multiple modes. So, you can use two of these modes to encode a qubit. If the molecular species is polar, two molecules can interact even when spatially separated.

Despite being notoriously difficult to control due to their complexity, Cheuk and colleagues have shown molecules are promising candidates. In their experiment, the scientists used a sophisticated tweezer array whereby a system of tightly focused laser beams manipulated individual calcium monofluoride molecules.

The laser system cooled the molecules to temperatures a fraction of a degree above absolute zero. At such an ungodly low temperature, vibration is almost nonexistent, making the molecules almost perfectly still. Pairs of calcium monofluoride were ultimately coaxed to enter a quantum entanglement state by correlating their dipolar interaction.

Reinforcing their findings, a separate group at Harvard University and MIT achieved similar results, validating the reliability and potential of molecular tweezer arrays in quantum science.

The fact that they got the same results verify the reliability of our results, Cheuk said in a press release. They also show that molecular tweezer arrays are becoming an exciting new platform for quantum science.

As we stand at the brink of a new era in quantum science, the implications of these discoveries are profound. From reshaping computing to redefining how we understand the fabric of our universe, the entanglement of molecules opens a world of possibilities, beckoning a future where quantum mechanics moves from theoretical wonder to practical reality.

The findings appeared in the journal Science.

In contrast to conventional computers, quantum computers are (or will be) built via the principles of quantum mechanics. Specifically, where information is stored in bits in a computer today, information in quantum computers will be stored in quantum bits, or qubits. A bit can be either a 0 or a 1, a binary system.Think of a light bulb that is either on or off, or a coin that is either heads or tails. In the mechanics of computing, a bit usually refers to an electrical signal that iseither on or off.

Like a bit, a qubit can be either 0 or 1, but it can also exist as limitless possibilities between those two states. Qubitsbuilt from subatomic particlesmight be created via the state of superposition between two electrons, for instance. Thus, a qubit is not just in a state of 0 or 1, it could be 0 and 1 at the same time, or any other combination between the states.

According to an article from Caltech, When an electron is in superposition, its different states can be thought of as separate outcomes, each with a particular probability of being observed. An electron might be said to be in a superposition of two different velocities or in two places at once.

Developing qubits offers the potential to store information orders of magnitude greater than what is possible with classical computation. The expectation is that quantum computers will thereby be able to perform operations beyond even todays supercomputers.

The usual suspects are at work developing quantum computers: IBM, Microsoft, Google Amazon, as well as some names youve not heard of. Importantly, theres a budding competition between Chinese and Western developers, part of the larger phenomenon of strategic capitalism, where national governments nurture and protect critical industriesrather than regulate them or, conversely, allow them to roam the globe freelyfrom their geostrategic rivals.

Kevin Klyman reports in Foreign Policy that the Biden administration is not waiting for the full development of the technology to institute export controls.

After controls on semiconductors, the Commerce Department is moving on to the next emerging technology it worries China could weaponize: quantum computing, Klyman says. Export controls on quantum computing hardware, error correction software, and the provision of cloud services to Chinese entities are poised to become the next front in the U.S.-China tech war.

Quantum computers will be able to tackle problems beyond the abilities of todays supercomputers. They will be able to evade most attempts at encryption, and so there will emerge a host of security questions that have yet to be answered. Machine learning and artificial intelligence will no doubt be accelerated. A few years ago, I wrote a book that discussed the limits of AI based largely on the notion that the semiconductors of classical computers would reach a point where they could not be reduced in size any further, that there is only so much processing power that can be confined to such a small space, and that the intelligence of a computer would reach its peak. Quantum Computing offers the possibility of blasting through those physical limits. AI + quantum computing could very well lead us to realize that theoretical possibility of an artificial general intelligence or indeed a super intelligence far beyond that of human intelligence.

The modeling and simulation of complex systems could also be possible with quantum computing. Everything from chemical systems to financial portfolios might be modeled. I have long argued that complex systems, especially, are exquisitely and intrinsically unpredictable, because of their sensitivity to initial conditions, their elaborate feedback loops, and other features that make prediction of the future behaviors of such systems all but impossible. It is more than plausible that quantum computers will permit more confident predictions of the behaviors of such systems.

If that proves the case, there are potential implications for the modeling and prediction of social systems, not just physical systems. If we gain the ability to model and predict, would we also gain the ability to control such systems, including the control over social systems?

In the early 1970s, Chile elected a socialist president, Salvador Allende, who promised to transfer property ownership from the wealthy to the state.In order to manage this socialist economy, Allende turned to Project Cybersyn. This was to be a central command room (opsroom) where data and information from the workings of the economy were to be ingested, analyzed and made available to the decision makers and managers.The system was to be run off a mainframe computer.

In the 1960s, the Soviet Union similarly worked on the idea that cybernetics could be employed to manage the economy, to unleash a consumers paradise to rival the one the West had developed. Allende was deposed in a coup, and so Project Cybersyn never really got off the ground. By the 1980s, free market ideology had taken hold of the Western imagination and the fall of the Soviet Union in the early 1990s seemingly ended any idea that the economy could be managed, even by a cybernetic system.

If quantum computers have the capacity to model, simulate, and potentially control complex systems, might we see a nation attempt something like Project Cybersyn again? Further, we might imagine an authoritarian seeking to extend cybernetic management beyond the economy to include control over society, culture and politics as well.Might quantum computing help to facilitate quantum authoritarianism?

After the PC revolution, we have become accustomed to thinking that all new technologies will eventually be democratized, made abundant and inexpensive and within access to all consumers. A very likely scenario is that at some point quantum computers will power all sorts of consumer-grade tools and applications, and that we will all carry a quantum computer in our pockets.

But it is also possible that quantum computing will remain an exclusive technology. Think of all the technologies we have developed that have not been made consumer-grade. One thinks of MRI scanners or F-16s or nuclear power plants. It is possible that relatively few quantum computers will be produced, and those that are made will be used only by specialists.Quantum computers might similarly remain in the hands of a few, an important infrastructure technology, perhaps, but one that will not be in the hands of consumers.Imagine Amazon Quantum Services.

Even if we dont end up having quantum computers in our homes, it is possible that the idea of the quantum will spread such that it will alter our societal worldview. Think of howafter the rise of the Internetthe concept of the network has reshaped how we see and understand reality. To take but one example, Anne-Marie Slaughter argues that diplomats and international relations scholars have shifted from using game theory to network theory to understand the world.

The idea of the network as a metaphor has had a powerful effect on our worldview. Might quantum become the new cultural metaphor that implicitly shapes our thoughts and actions?The idea of being both-and or having alternate states existing simultaneously might find its way into our everyday language, changing how we view everything from social relations to the operations of the economy to how we teach schoolchildren to the way ideas go viral.

The metaphor of quantum superposition could very well influence the work of artists, the writing of poets and novelists, the actions of corporate boards, and the decisions of policymakerssimultaneously.

Cornell Scientists Have Discovered a Hidden Quantum State – SciTechDaily

Cornell researchers discovered a quantum spin-glass state in quantum computing, offering insights into error correction and revealing hidden orders in quantum algorithms, potentially leading to new quantum state classifications and advances in quantum computing.

At the microscopic level, window glass exhibits a curious blend of properties. Its atoms are disordered like a liquid, yet they possess the rigidity of a solid; when a force is applied to one atom, it affects all others.

Its an analogy physicists use to describe a quantum state called a quantum spin-glass, in which quantum mechanical bits (qubits) in a quantum computer demonstrate both disorder (taking on seemingly random values) and rigidity (when one qubit flips, so do all the others). A team of Cornell researchers unexpectedly discovered the presence of this quantum state while conducting a research project designed to learn more about quantum algorithms and, relatedly, new strategies for error correction in quantum computing.

Measuring the position of a quantum particle changes its momentum and vice versa. Similarly, for qubits, there are quantities that change one another when they are measured. We find that certain random sequences of these incompatible measurements lead to the formation of a quantum spin-glass, said Erich Mueller, professor of physics in the College of Arts and Sciences (A&S). One implication of our work is that some types of information are automatically protected in quantum algorithms whichshare the features of our model.

The study was recently published in Physical Review B. The lead author is Vaibhav Sharma, a doctoral student in physics.

Assistant professor of physicsChao-Ming Jian(A&S) is a co-author along with Mueller. All three conduct their research at CornellsLaboratory of Atomic and Solid State Physics(LASSP). The research received funding from a College of Arts and SciencesNew Frontier Grant.

We are trying to understand generic features of quantum algorithms features which transcend any particular algorithm, Sharma said. Our strategy for revealing these universal features was to study random algorithms.We discovered that certain classes of algorithms lead to hidden spin-glass order. We are now searching for other forms of hidden order and think that this will lead us to a new taxonomy of quantum states.

Random algorithms are those that incorporate a degree of randomness as part of the algorithm e.g., random numbers to decide what to do next.

Muellers proposal for the2021 New Frontier GrantAutonomous Quantum Subsystem Error Correction aimed to simplify quantum computer architectures by developing a new strategy to correct for quantum processor errors caused by environmental noise that is, any factor, such as cosmic rays or magnetic fields, that would interfere with a quantum computers qubits, corrupting information.

The bits of classical computer systems are protected by error-correcting codes, Mueller said; information is replicated so that if one bit flips, you can detect it and fix the error. For quantum computing to be workable now and in the future, we need to come up with ways to protect qubits in the same way.

The key to error correction is redundancy, Mueller said. If I send three copies of a bit, you can tell if there is an error by comparing the bits with one another. We borrow language from cryptography for talking about such strategies and refer to the repeated set of bits as a codeword.

When they made their discovery about spin-glass order, Mueller and his team were looking into a generalization, where multiple codewords are used to represent the same information. For example, in a subsystem code, the bit 1 might be stored in 4 different ways: 111; 100; 101; and 001.

The extra freedom that one has in quantum subsystem codes simplifies the process of detecting and correcting errors, Mueller said.

The researchers emphasized that they werent simply trying to generate a better error protection scheme when they began this research. Rather, they were studying random algorithms to learn general properties of all such algorithms.

Interestingly, we found nontrivial structure, Mueller said. The most dramatic was the existence of this spin-glass order, which points toward there being some extra hidden information floating around, which should be useable in some way for computing, though we dont know how yet.
