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 […]
Diamond color centers are a well researched field, but using them at scale as qubits was out of reach until recently. Their Quantum Transistor device (patent pending) resolves the charge stability issue and few more […]
2025 has been a year of truly significant progress in the quantum technology world, with continued advancements in hardware, software, and ecosystems bringing us closer to the goal of transformative quantum applications in computing, communications […]
Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz frequency combs using a quantum antenna made from Rydberg atoms. By combining atomic electrometry with a powerful terahertz-to-light […]
Insider Brief NSF’s Directorate for Technology, Innovation and Partnerships has launched the Tech Labs initiative to support independent, full-time research teams tackling technical challenges that are difficult for universities or industry labs to address alone, […]
Qolab, a developer of utility-scale superconducting quantum computers, has announced a strategic investment from Western Digital (Nasdaq: WDC). The partnership is designed to accelerate the commercialization of quantum systems by applying the data storage giant’s […]
The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU University of Kaiserslautern-Landau have therefore implemented a quantum simulation of the Josephson effect: They separated two Bose-Einstein condensates (BECs) […]
