In the quest to harness the power of quantum computing, akin to its classical counterpart, the need for effective information storage persists. Just as your current computer stores data, whether it’s cherished photos or vital reminders, quantum computing necessitates a means to store and process quantum information. As this burgeoning field explores new frontiers, a breakthrough method has emerged. Recently featured in the journal Nature Physics, Mohammad Mirhosseini, an assistant professor of electrical engineering and applied physics at the California Institute of Technology (Caltech), has unveiled an innovative technique for translating electrical quantum states into sound and vice versa—a pivotal advancement in quantum information storage.

Mirhosseini’s groundbreaking approach holds promise for storing quantum information produced by future quantum computers, which are anticipated to be constructed using electrical circuits. The mechanism at play harnesses phonons, which are analogous to photons—the particles of light. This method capitalizes on the capacity of phonons, akin to sound particles, for storing quantum information, facilitated by the creation of compact devices to hold these mechanical waves.

Researchers have achieved a significant breakthrough in the realm of quantum physics by generating a peculiar particle within a quantum computer. This particle, known as a non-abelian anyon, possesses an intriguing ability to retain its past history. This newfound capability could potentially facilitate deeper exploration into the intricacies of quantum phenomena.

The non-abelian anyons, referred to as quasiparticles, have the unique property of preserving records of their previous positions when exchanged with one another. This distinctive feature allows physicists to intricately weave these particles together, forming complex entangled configurations that exhibit novel and unusual behaviors.

Intel recently revealed its latest quantum chip, “Tunnel Falls,” marking a significant milestone in its quantum computing roadmap. This silicon-based chip boasts 12 qubits and is primarily intended as a research test chip rather than a commercially available product. With this release, Intel aims to advance its long-term strategy of developing a complete commercial quantum computing system. While there are still challenges to overcome on the path to a fault-tolerant quantum computer, the academic community can now explore this technology and accelerate research development.

Jim Clarke, Intel’s director of Quantum Hardware, emphasized that Tunnel Falls represents the company’s most advanced silicon spin qubit chip to date, drawing on Intel’s extensive experience in transistor design and manufacturing. He stated, “The release of the new chip is the next step in Intel’s long-term strategy to build a full-stack commercial quantum computing system. While there are still fundamental questions and challenges that must be solved along the path to a fault-tolerant quantum computer, the academic community can now explore this technology and accelerate research development.”

A weird and wonderful array of technologies are competing to become the standard-bearer for quantum computing. The latest contender wants to encode quantum information in sound waves.

One thing all quantum computers have in common is the fact that they manipulate information encoded in quantum states. But that’s where the similarities end because those quantum states can be induced in everything from superconducting circuits to trapped ions, ultra-cooled atoms, photons, and even silicon chips.

While some of these approaches have attracted more investment than others, we’re still a long way from the industry settling on a common platform. And in the world of academic research, experimentation still abounds.

Now, a team from the University of Chicago has taken crucial first steps towards building a quantum computer that can encode information in phonons, the fundamental quantum units that make up sound waves, in much the same way that photons make up light beams.

The basic principles of how you could create a “phononic” quantum computer are fairly similar to those used in “photonic” quantum computers. Both involve generating and detecting individual particles or quasiparticles and manipulating them using beamsplitters and phase shifters. Phonons are quasiparticles because although they act like particles as far as quantum mechanics are concerned, they are actually made up of the collective behavior of large numbers of atoms.

A groundbreaking quantum computer named Juizhang, developed by a team led by renowned scientist Pan Jianwei, has made a remarkable claim of being able to process artificial intelligence (AI) tasks 180 million times faster than conventional computers, as reported by the South China Morning Post. Pan Jianwei, often referred to as the “father of quantum” in China, has been instrumental in advancing the country’s expertise in quantum computing, marking a significant stride in the field.

Unlike traditional computing, where bits can only represent one or zero, a quantum computing unit, or qubit, has the unique ability to exist in both states simultaneously. This characteristic allows qubits to process information faster than classical computers by considering all possible combinations at once.

Photonic bound states could advance medical imaging and quantum computing

For the first time, scientists at the University of Sydney and the University of Basel in Switzerland have demonstrated the ability to manipulate and identify small numbers of interacting photons — packets of light energy — with high correlation. advertisement This unprecedented achievement represents an important landmark in the development of quantum technologies.

It is published today in Nature Physics. Stimulated light emission, postulated by Einstein in 1916, is widely observed for large numbers of photons and laid the basis for the invention of the laser. With this research, stimulated emission has now been observed for single photons. Specifically, the scientists could measure the direct time delay between one photon and a pair of bound photons scattering off a single quantum dot, a type of artificially created atom.

“This opens the door to the manipulation of what we can call ‘quantum light’,” Dr Sahand Mahmoodian from the University of Sydney School of Physics and joint lead author of the research said.
