Quantum 9, 1877 (2025). https://doi.org/10.22331/q-2025-10-06-1877 We study relaxations of entanglement-assisted quantum channel coding and establish that non-signaling assistance and a natural semi-definite programming relaxation — termed meta-converse — are equivalent in terms of success probabilities. […]
Quantum 9, 1876 (2025). https://doi.org/10.22331/q-2025-10-06-1876 We apply the recent graphical framework of “Quantum Lego” to XP stabilizer codes where the stabilizer group is generally non-Abelian. We show that the idea of operator matching continues to […]
Quantum 9, 1875 (2025). https://doi.org/10.22331/q-2025-10-06-1875 We explore indefinite causal order between events in the context of quasiclassical spacetimes in superposition. We introduce several new quantifiers to measure the degree of indefiniteness of the causal order […]
Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from supermassive black holes could be accelerating […]
Dates: Monday, March 16, 2026 to Friday, March 20, 2026 Web page: 2026.quantumresources.science Submission deadline: Friday, October 31, 2025 We are pleased to announce the fourth iteration of the workshop “Quantum Resources”, to take place […]
Orientum, a developer of quantum financial algorithms, has announced plans to develop a middleware platform containing all quantum financial algorithms by 2030. The announcement, made at the AI Festa Quantum 3.0 Forum, outlines a strategy […]
Image of an EeroQ quantum device for single electron trapping and control. Credit: Eeroq EeroQ has reported a significant experimental breakthrough for its electron-on-helium quantum computing platform, publishing results this week in Physical Review X […]
Scientists at OIST have, for the first time, directly tracked the elusive “dark excitons” inside atomically thin materials. These quantum particles could revolutionize information technology, as they are more stable and resistant to environmental interference […]
Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region untouched by current observatories. Built with optical resonators and atomic clocks, the compact detectors can fit on […]
