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 […]
PRESS RELEASE — CAMBRIDGE, Mass. & GOTHENBURG, Sweden/July 21, 2022 — (BUSINESS WIRE) — Atlantic Quantum, a developer of scalable quantum computers, today announced a $9 million seed investment led by The Engine, the venture firm spun out of MIT that […]
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 […]
Several people have complained that Shtetl-Optimized has become too focused on the niche topic of “people being mean to Scott Aaronson on the Internet.” In one sense, this criticism is deeply unfair—did I decide that […]
For decades computers have been synonymous with binary information — zeros and ones. Now a team has realized a quantum computer that breaks out of this paradigm and unlocks additional computational resources, hidden in almost […]
Matching particles and antiparticles are small units of matter that have the same mass but opposite electric charges. Typically, these units of matter with opposite electric charge tend to annihilate one another. Click to rate […]
If you’ve been following the math news this month, you know that the 35-year-old number theorist James Maynard won a Fields Medal — the highest honor for a mathematician. Maynard likes math questions that “are […]
