This month over two weeks, the Institute for Quantum Computing (IQC) proudly marked the culmination of the 16th annual session of the Quantum School for Young Students (QSYS), a distinctive enrichment program that opened its […]
Quantum 7, 1091 (2023). https://doi.org/10.22331/q-2023-08-22-1091 When an emitter ensemble interacts with the electromagnetic field, dipole-dipole interactions are induced between the emitters. The magnitude and shape of these interactions are fully determined by the specific form […]
Quantum 7, 1090 (2023). https://doi.org/10.22331/q-2023-08-22-1090 Semi-device-independent quantum key distribution aims to achieve a balance between the highest level of security, device independence, and experimental feasibility. Semi-quantum key distribution presents an intriguing approach that seeks to […]
In early June, buzz built as mathematicians landed at London’s Heathrow Airport. Their destination was the University of Oxford and a conference in honor of the 65th birthday of Michael Hopkins, a mathematician at Harvard […]
Quantum 7, 1089 (2023). https://doi.org/10.22331/q-2023-08-22-1089 We investigate a family of fault-tolerant quantum error correction schemes based on the concatenation of small error detection or error correction codes with the three-dimensional cluster state. We propose fault-tolerant […]
Quantum 7, 1088 (2023). https://doi.org/10.22331/q-2023-08-22-1088 Given the importance of quantum reference frames (QRFs) to both quantum and gravitational physics, it is pertinent to develop a systematic method for switching between the descriptions of physics relative […]
Insider Brief Government agencies just released a factsheet today about the impacts of quantum capabilities. The agencies urge all organizations, especially those that support critical infrastructure, to begin early planning for migration to post-quantum cryptographic […]
Insider Brief D-Wave introduced algorithmic updates to its CQM solver that deliver increased performance for existing binary problem classes. Binary problem classes included allocation, portfolio optimization and satisfiability. D-Wave tested the binary problem solver on […]
Insider Brief Rigetti introduced an innovative multi-chip tunable coupler designed to facilitate qubit interactions across separate chips. The core of this approach rests on a floating tunable coupler. The work may set the stage for […]
Ben Brubaker wrote a long piece for Quanta magazine about meta-complexity. The first three-quarters are a giant refresher on the story of computability and complexity theory in the 20th century—including Turing, Gödel, Shannon, Cook, Karp, […]
