Quantum 9, 1735 (2025). https://doi.org/10.22331/q-2025-05-06-1735 We study what can or cannot be certified in communication scenarios where the assumption of independence and identical distribution (iid) between experimental rounds fails. In this respect, we prove that […]
Quantum 9, 1734 (2025). https://doi.org/10.22331/q-2025-05-06-1734 We propose in this work a practical approach to address the longstanding and challenging problem of quantum separability, leveraging the correlation matrices of generic observables. General separability conditions are obtained […]
Quantum 9, 1733 (2025). https://doi.org/10.22331/q-2025-05-06-1733 Recently, Apers and Piddock [TQC ’23] strengthened the connection between quantum walks and electrical networks via Kirchhoff’s Law and Ohm’s Law. In this work, we develop a new multidimensional electrical […]
Cisco has formally launched its Quantum Networking Lab in Santa Monica, California alongside the introduction of a prototype quantum entanglement chip developed with UC Santa Barbara. The photonic integrated chip generates up to one million […]
Researchers have developed a new protocol for benchmarking quantum gates, a critical step toward realizing the full potential of quantum computing and potentially accelerating progress toward fault-tolerant quantum computers. Click to rate this post! [Total: […]
Researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and DOE’s Pacific Northwest National Laboratory (PNNL) have uncovered an unexpected interface layer that may be hindering the performance of superconducting qubits, the building […]
Insider Brief QphoX, Rigetti, and the UK’s National Quantum Computing Centre received a multinational grant to demonstrate optical readout of superconducting qubits using light over optical fiber. The approach relies on microwave-to-optical transduction at cryogenic […]
Quantum technologies, which leverage quantum mechanical effects to process information, could outperform their classical counterparts in some complex and advanced tasks. The development and real-world deployment of these technologies partly relies on the ability to […]
Insider Brief: Origin Quantum released its fourth-generation control system, Tianji 4.0, which has the potential to support over 500 qubits as well as China’s efforts to develop scalable, industrial-grade quantum computing infrastructure. Tianji 4.0 introduces […]
Insider Brief Researchers from KAIST, Argonne National Laboratory, and the University of Illinois demonstrated for the first time that magnets can be used to perform quantum computing operations. The team developed a photon-magnon hybrid chip […]
