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, […]
Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Click to rate this post! [Total: 0 Average: 0]You have already voted for this article
Since the 17th century, when Isaac Newton and Christiaan Huygens first debated the nature of light, scientists have been puzzling over whether light is best viewed as a wave or a particle—or perhaps, at the […]
Murray Thom, Vice President of Quantum Business Innovation at D-Wave Systems is interviewed by Yuval Boger. Murray and Yuval discuss D-Wave case studies, why customers move or don’t move to production, their future gate-based machine, […]
