Quantum 10, 2212 (2026). https://doi.org/10.22331/q-2026-09-21-2212 Efficiently implementing Clifford circuits is crucial for quantum error correction and quantum algorithms. Linear reversible circuits, equivalent to circuits composed of CNOTxspace gates, have important applications in classical computing. In […]
Insider Brief Diraq and Dell Technologies are collaborating on integrating Diraq’s silicon spin-qubit processor with Dell’s classical HPC infrastructure in a co-located testbed. Dell has deployed a small HPC cluster at Diraq’s Sydney laboratory to […]
Insider Brief GlobalFoundries and the U.S. Department of Commerce finalized a $375 million CHIPS R&D award to support the company’s Quantum Technology Solutions business. The five-year award is tied to milestones and is intended to […]
Insider Brief QNu Labs has launched QShield 2.0, the platform powering its National Cryptographic Assessment & Assurance Framework (NCAAF) for cryptographic discovery, risk assessment and continuous assurance. NCAAF uses five QShield 2.0 modules covering quantum […]
Insider Brief Creotech Quantum has signed a €2.33 million European Space Agency project to develop and demonstrate superconducting nanowire single-photon detectors for quantum key distribution ground stations and advanced optical communications. Creotech Quantum will lead […]
A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. The discrepancy is tiny, but for one of nature’s […]
Physicists have detected strong evidence that heavy, fleeting Z bosons can become quantum entangled during Higgs boson decays at CERN’s Large Hadron Collider. The result shows that Einstein’s “spooky action at a distance” survives even […]
Quantum Motion promoted Dr. Anna Stockklauser to CPO, Silicon Quantum Computing appointed John Hollister as CFO, Lawrence Semiconductor named Don Garrison GM and COO, and Pasqal added Roberto Mauro as CPO and Joëlle Lumb as […]
IBM Research has introduced Spacetime Probabilistic Error Cancellation (Spacetime PEC), a hybrid error-handling framework that significantly reduces the sampling overhead in quantum computing. This new protocol combines Probabilistic Error Cancellation (PEC) with post-selected Quantum Error […]
University of Pennsylvania researchers have achieved a breakthrough in quantum computing by demonstrating single-gate, parallelized multipartite entanglement on a room-temperature diamond quantum register. They successfully generated a four-qubit Greenberger–Horne–Zeilinger (GHZ) state in just 14.8 microseconds, […]
