A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming stable structures that generate mass […]
Quantum 9, 1949 (2025). https://doi.org/10.22331/q-2025-12-15-1949 The eigenstate thermalization hypothesis (ETH) is the leading interpretation in our current understanding of quantum thermalization. Recent results uncovered strong connections between quantum correlations in thermalizing systems and the structure […]
Insider Brief New research from Quantinuum and Hiverge shows that large language model–driven systems can automatically generate quantum chemistry algorithms that match or outperform leading human-designed methods while using far fewer quantum resources. Using Hiverge’s […]
Quantum 9, 1948 (2025). https://doi.org/10.22331/q-2025-12-15-1948 Building large-scale quantum communication networks has its unique challenges. Here, we demonstrate that a network-wide synergistic usage of quantum memories distributed in a quantum communication network offers a fundamental advantage. […]
Insider Brief QuantumDiamonds GmbH announced a €152 million (about $178 million US) plan to build the world’s first production facility for quantum-based semiconductor inspection systems, positioning the company and Germany as strategic players in advanced […]
Quantum 9, 1947 (2025). https://doi.org/10.22331/q-2025-12-15-1947 We propose an algebraic geometry-inspired approach for constructing entangled subspaces within the Hilbert space of a multipartite quantum system. Specifically, our method employs a modified Veronese embedding, restricted to the […]
Quantum 9, 1946 (2025). https://doi.org/10.22331/q-2025-12-15-1946 Effective Hamiltonian calculations for large quantum systems can be both analytically intractable and numerically expensive using standard techniques. In this manuscript, we present numerical techniques inspired by Nonperturbative Analytical Diagonalization […]
Quantum 9, 1945 (2025). https://doi.org/10.22331/q-2025-12-15-1945 Entanglement distillation, the process of converting weakly entangled states into maximally entangled ones using Local Operations and Classical Communication (LOCC), is pivotal for robust entanglement-assisted quantum information processing in error-prone […]
Quantum 9, 1944 (2025). https://doi.org/10.22331/q-2025-12-15-1944 Recent years have seen a surge of interest in exceptional points in open quantum systems. The natural approach in this area has been the use of Markovian master equations. While […]
QuEra will release a new roadmap to commercial quantum advantage in 2026. They presented progress to commercial quantum advantage over regular computers. They gave a talk at the Q2b 2025 conference (quantum to business). Brian […]
