Quantum 9, 1937 (2025). https://doi.org/10.22331/q-2025-12-11-1937 We present a finite-size security proof of the decoy-state BB84 QKD protocol against coherent attacks, using entropic uncertainty relations, for imperfect detectors. We apply this result to the case of […]
Quantum 9, 1936 (2025). https://doi.org/10.22331/q-2025-12-11-1936 Recently, usage of detecting regions facilitated the discovery of new circuits for fault-tolerantly implementing the surface code. Building on these ideas, we present LUCI, a framework for constructing fault-tolerant circuits […]
Quantum Corridor, in collaboration with Toshiba International Corporation (TIC) and partners, has successfully demonstrated quantum-secured communication using Quantum Key Distribution (QKD) over a live commercial metropolitan fiber network connecting data centers in Illinois and Indiana. […]
SandboxAQ, a company delivering solutions at the intersection of AI and quantum techniques, has announced a five-year agreement with the Department of War (DoW) Chief Information Officer (CIO) to accelerate the discovery and inventory of […]
Vanderbilt University and EPB of Chattanooga have announced the establishment of the Institute for Quantum Innovation, a new center for research, innovation, and graduate-level education in quantum science and technology. The initiative aims to position […]
University of Iowa researchers have discovered a method to “purify” photons, an advance that could make optical quantum technologies more efficient and more secure. Click to rate this post! [Total: 0 Average: 0]You have already […]
Quantum Art, an Israeli developer of full-stack quantum computers based on trapped-ion qubits, has closed a $100 million Series A funding round. The investment brings the company’s total funding to date to $124 million and […]
If quantum computing is going to become an every-day reality, we need better superconducting thin films, the hardware that enables storage and processing of quantum information. Too often, these thin films have impurities or other […]
Nu Quantum, a UK-based company specializing in distributed quantum computing, has closed an oversubscribed $60 million Series A funding round. The funding is reported to be the largest ever raised by a pure-play quantum networking […]
QUDORA Technologies, a German developer of trapped-ion quantum computers, has announced the integration of QC Design’s Plaquette software into its R&D workflow. Plaquette is a quantum design-automation platform built to help hardware teams engineer scalable […]
