Within the next three months, Honeywell will bring to market the world’s most powerful quantum computer in terms of quantum volume, a measure of quantum capability that goes beyond the number of qubits. Quantum volume measures computational ability, indicating the …

Users have developed 200+ early quantum applications on D-Wave systems, including airline scheduling, election modeling, quantum chemistry simulation, automotive design, preventative healthcare, logistics, and much more. On Feb 27, 2020 D-Wave announced the immediate availability of Leap 2, the first …

researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can’t. They trace each computing path for correct behavior. This modular verification reduces the complexity of …

The researchers at QuTech, a collaboration of TU Delft and TNO, have built two germanium transistors that can be the building blocks for fast quantum computing. Before this work it was not possible to perform quantum calculations using only transistors. …

IBM announced a new 28-qubit quantum system backend, Raleigh and achieved a system demonstrating Quantum Volume of 32. This is double the quantum volume of 16 of a prior IBM system. Quantum Volume (QV) is a hardware-agnostic metric that we …

Intel Labs unveiled a first-of-its-kind cryogenic control chip — code-named “Horse Ridge” — that will speed up development of full-stack quantum computing systems. Horse Ridge will enable control of multiple quantum bits (qubits) and set a clear path toward scaling …

This article has information from the quantum computer expert John Preskill. We are going to get more and better quality qubits with lower error rates. The overhead cost for error correction improves as gate error rate declines. The Google Quantum …
