Quantum 10, 1976 (2026). https://doi.org/10.22331/q-2026-01-20-1976 Recent theoretical results in quantum machine learning have demonstrated a general trade-off between the expressive power of quantum neural networks (QNNs) and their trainability; as a corollary of these results, […]
Quantum 10, 1975 (2026). https://doi.org/10.22331/q-2026-01-20-1975 For many problems, quantum algorithms promise speedups over their classical counterparts. However, these results predominantly rely on asymptotic worst-case analysis, which overlooks significant overheads due to error correction and the […]
Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, they produce unique effects not seen in individual particles. Understanding how quantum spins interact to produce this behavior […]
Insider Brief Researchers demonstrated a new form of Floquet engineering in which excitons, rather than intense light fields, act as the periodic drive, enabling stronger and more efficient modification of electronic band structures in quantum […]
Insider Brief Tensor AI Solutions has been commissioned by the German Aerospace Center under its Quantum Computing Initiative to support the QCMineral | QUADRANT project, which aims to use quantum-enabled simulations to design redox materials […]
Universidad Politécnica de Madrid and Q*Bird have deployed Spain’s first operational multi-node Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) network across high-security government sites in Madrid. The hub-and-spoke network connects three end nodes over 30–50 km fiber […]
Researchers from the University of Waterloo’s Faculty of Science and the Institute for Quantum Computing (IQC) are prioritizing collaboration over competition to advance quantum computer development and the field of quantum information. They are doing […]
