Atlantic Quantum is a spinout from the Engineering Quantum Systems (EQuS) group at MIT formed in early 2022. They are developing a scalable, fault tolerant quantum processor using superconducting technology. They assert that they have […]
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 […]
