Quantum information platforms are based on qubits that talk to each other and photons (optical and microwave) are the carrier of choice—to date, to transfer quantum states between qubits. However, in some solid-state systems, acoustic vibrational properties of the material themselves known as phonons can be advantageous. In a recent study published on Science Advances, B. Bienfait and colleagues at the…

Physicists set a new record of quantum memory efficiency
Like memory in conventional computers, quantum memory components are essential for quantum computers—a new generation of data processors that exploit quantum mechanics and can overcome the limitations of classical computers. With their potent computational power, quantum computers may push the boundaries of fundamental science to create new drugs, explain cosmological mysteries, or enhance accuracy of forecasts and optimization plans. Quantum computers…
Remote connections? Detangling entanglement in quantum physics
Quantum computers, quantum cryptography and quantum (insert name here) are often in the news these days. Articles about them inevitably refer to entanglement, a property of quantum physics that makes all these magical devices possible. …
New insights into quantum measurements
Researchers from the University of Bristol have shed new light on the process of quantum measurement, one of the defining, and most quantum features of quantum mechanics. …
The spin doctors: Researchers discover surprising quantum effect in hard disk drive material
Scientists find surprising way to affect information storage properties in metal alloy. …
New robust device may scale up quantum tech, researchers say
Researchers have been trying for many years to build a quantum computer that industry could scale up, but the building blocks of quantum computing, qubits, still aren’t robust enough to handle the noisy environment of what would be a quantum computer. …
Atom interaction discovery valuable for future quantum technologies
By breaking with conventionality, University of Otago physicists have opened up new research and technology opportunities involving the basic building block of the world—atoms. …
Atomic beams shoot straighter via cascading silicon peashooters
To a non-physicist, an “atomic beam collimator” may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely to someday land in handheld devices. …
New method enables quantum simulations on larger systems
Through randomly selected measurements, Austrian physicists can now determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger number of quantum particles. In Science, physicists from Innsbruck, Austria, report on the first successful demonstration of this method. …
World-record quantum computing result for Sydney teams
A world-record result in reducing errors in semiconductor ‘spin qubits’, a type of building block for quantum computers, has been achieved using the theoretical work of quantum physicists at the University of Sydney Nano Institute and School of Physics. …
