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 ...
Quantum computers are experimental devices that promise exponential speedups on some computational problems. Where a bit in a classical computer can represent either a 0 or a 1, a quantum bit, or qubit, can represent 0 and ...
Scientists are vigorously competing to transform the counterintuitive discoveries about the quantum realm from a century past into technologies of the future. The building block in these technologies is the quantum bit, or ...
UNSW Sydney-led research paves the way for large silicon-based quantum processors for real-world manufacturing and application.
Quantum computers promise speedy solutions to some difficult problems, but building large-scale, general-purpose quantum devices is a problem fraught with technical challenges.
(Phys.org)—Constructing quantum computers and other quantum devices requires the ability to leverage quantum properties such as superposition and entanglement – but these effects are fragile and therefore hard to maintain. ...
Nothing exists in a vacuum, but physicists often wish this weren't the case. If the systems that scientists study could be completely isolated from the outside world, things would be a lot easier.
Some classical computers have error correction built into their memories based on bits; quantum computers, to be workable in the future, will need error correction mechanisms, too, based on the vastly more sensitive qubits.
USC scientists have demonstrated a theoretical method to enhance the performance of quantum computers, an important step to scale a technology with potential to solve some of society's biggest challenges.
A precision diagnostic developed at the Department of Energy's Sandia National Laboratories is emerging as a gold standard for detecting and describing problems inside quantum computing hardware.
