In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips. Click to rate this post! [Total: 0 Average: […]
Quantum 9, 1919 (2025). https://doi.org/10.22331/q-2025-11-20-1919 Sequential methods for quantum hypothesis testing offer significant advantages over fixed-length approaches, which rely on a predefined number of state copies. Despite their potential, these methods remain underexplored for unambiguous […]
Quantum 9, 1918 (2025). https://doi.org/10.22331/q-2025-11-20-1918 The spectral variant of the quantum marginal problem asks: Given prescribed spectra for a set of overlapping quantum marginals, does there exist a compatible joint state? The main idea of […]
Quantum 9, 1917 (2025). https://doi.org/10.22331/q-2025-11-20-1917 We study a qDRIFT-type randomized method to simulate Lindblad dynamics by decomposing its generator into an ensemble of Lindbladians, $mathcal{L} = sum_{a in mathcal{A}} mathcal{L}_a$, where each $mathcal{L}_a$ comprises a […]
Quantum 9, 1916 (2025). https://doi.org/10.22331/q-2025-11-20-1916 To better understand quantum computation we can search for its limits or no-gos, especially if analogous limits do not appear in classical computation. Classical computation easily implements and extensively employs […]
Quantum computers, which operate leveraging effects rooted in quantum mechanics, have the potential of tackling some computational and optimization tasks that cannot be solved by classical computers. Instead of bits (i.e., binary digits), which are […]
IBM (NYSE: IBM) and Cisco (NASDAQ: CSCO) have announced their intention to collaborate on the foundational architecture for networked distributed quantum computing, targeting realization as soon as the early 2030s. The partnership aims to combine […]
Near the end of my last post, I made a little offhand remark: [G]iven the current staggering rate of hardware progress, I now think it’s a live possibility that we’ll have a fault-tolerant quantum computer […]
Overview In this special episode, host Veronica Combs is joined by Leland Miller and Mike Kuiken, members of the US-China Economic and Security Review Commission. They discuss the Commission’s 2025 report on US-China relations and […]
Classiq, a quantum software company, has announced a joint demonstration with BQP, a quantum-powered simulation startup, and NVIDIA showcasing an advancement in hybrid quantum-classical simulation for Computational Fluid Dynamics (CFD) and digital twin workloads. The […]
