Quantum 9, 1737 (2025). https://doi.org/10.22331/q-2025-05-06-1737 Recent developments in domains such as non-local games, quantum interactive proofs, and quantum generative adversarial networks have renewed interest in quantum game theory and, specifically, quantum zero-sum games. Central to […]
Insider Brief IonQ has completed its acquisition of a controlling stake in ID Quantique, expanding its capabilities in quantum-safe networking and quantum detection systems. The deal adds IDQ’s portfolio of QKD systems, QRNGs, and single-photon […]
Quantum 9, 1736 (2025). https://doi.org/10.22331/q-2025-05-06-1736 Quantum networks are of high interest nowadays and a quantum internet has been long envisioned. Network-entanglement adapts the notion of entanglement to the network scenario and network-entangled states are considered […]
Researchers at the University of Rochester and Rochester Institute of Technology recently connected their campuses with an experimental quantum communications network using two optical fibers. In a new paper published in Optica Quantum, scientists describe […]
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 […]
