Taking a Bayesian approach to training quantum circuits may lead to circuits that are faster to execute and less noisy than the circuits, according to a team of Quantinuum scientists. These new, more robust circuits […]
Google Quantum AI team members report that the Quantum Virtual Machine (QVM) is ready — and it is designed to emulate the experience and results of programming one of the quantum computers in the Google […]
UNIVERSITY NEWS — A University of Minnesota Twin Cities-led team received a $1.4 million award from the W. M. Keck Foundation to study a new process that combines quantum physics and biochemistry. If successful, the […]
Researchers at the Weizmann Institute of Science, the Barcelona Institute of Science and Technology and the National Institute for Material Science in Tsukuba (Japan) have recently probed a Chern mosaic topology and Berry-curvature magnetism in […]
Via large-scale simulations on supercomputers, a research team from the Department of Physics, the University of Hong Kong (HKU), discovered clear evidence to characterize a highly entangled quantum matter phase—the quantum spin liquid (QSL), a […]
Series A2 Funding IQM Quantum Computers (IQM), a Finland-based company that provides on-premises quantum computers for supercomputing data centres and research labs, announced today it has raised €128 million ($128m) in Series A2 funding led by […]
Quantum technology, like many other types of technology, evokes many ethical questions. One person interested in answering those questions is Mira Pijselman, a Senior Consultant in Digital Ethics at Ernst & Young LLP (EY). Pijselman […]

Security of quantum key distribution with detection-efficiency mismatch in the multiphoton case0 (0)
Quantum 6, 771 (2022). https://doi.org/10.22331/q-2022-07-22-771 Detection-efficiency mismatch is a common problem in practical quantum key distribution (QKD) systems. Current security proofs of QKD with detection-efficiency mismatch rely either on the assumption of the single-photon light […]
One of the key engineering activities to achieve qubits that have the longest coherence times is materials engineering to produce purified substances that will help reduce the impact of things that will degrade the coherence […]
