Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain […]
Executive Summary France’s quantum ecosystem continued to expand in July 2026 through a combination of government oversight, industrial scaling, international partnerships and commercial growth, even as policymakers acknowledged intensifying global competition. The French Court of […]
Insider Brief The article explains why cryptographic agility is becoming a key requirement for organizations preparing for post-quantum cryptography migration and future algorithm changes. Crypto-agile systems allow organizations to replace cryptographic algorithms through adaptable architectures […]
Quantum 10, 2181 (2026). https://doi.org/10.22331/q-2026-07-31-2181 We construct several families of entanglement-assisted quasi-cyclic quantum LDPC (EA-QC-QLDPC) codes via structured tilings of permutation matrices. The entanglement-unassisted portion of the joint Tanner graph of the proposed EA-QC-QLDPC code […]
