Not long ago William MacAskill, the founder of the Effective Altruist movement, visited Austin, where I got to talk with him in person for the first time. I was a fan of his book What […]
Alice & Bob, a French-based quantum computing company specializing in fault-tolerant systems using cat qubits, has announced a strategic partnership with TERATEC, a leading French initiative for high-performance computing (HPC) and simulation. As a new […]
Algorithmiq, a quantum computing company specializing in chemistry and life sciences, has announced a collaboration with Microsoft to accelerate the development of quantum chemistry algorithms designed specifically for the fault-tolerant quantum hardware era. The partnership […]
Kyndryl (NYSE: KD), a leading provider of mission-critical enterprise technology services, has unveiled its Quantum Safe Assessment service to help enterprises prepare for the security threats posed by quantum computing. The new service is designed […]
Quantum 9, 1940 (2025). https://doi.org/10.22331/q-2025-12-11-1940 (i) We point out that every local unitary circuit of depth smaller than the linear system size is easily distinguished from a global Haar random unitary if there is a […]
Quantum 9, 1939 (2025). https://doi.org/10.22331/q-2025-12-11-1939 We propose a Bell test experiment using momentum-entangled atom pairs of different masses, specifically metastable helium isotopes ${}^{3}He^{*}$ and ${}^{4}He^{*}$, though the method extends to other atom species. Entanglement is […]
Qubit Pharmaceuticals, a Paris-based deep-tech company, has announced two simultaneous milestones solidifying its position in advanced quantum algorithm development for molecular simulation. The breakthroughs address both the theoretical speed limits of quantum computing and the […]
Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, communication and information processing. Click to rate this […]
Quantum 9, 1938 (2025). https://doi.org/10.22331/q-2025-12-11-1938 The detection and quantification of non-Markovianity, a.k.a. memory, in quantum systems is a central problem in the theory of open quantum systems. There memory is as a result of the […]
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 […]
