IBM has doubled the power of its quantum computer

By using a 27-qubit client-deployed system, IBM has reached a new quantum computing milestone by achieving a quantum volume of 64 which is double the amount its 28-qubit backend Raleigh achieved back in January.

While quantum computers are usually measured by the amount of quantum bits or qubits they have, quantum volume is a measure of quantum capability that goes beyond the number of qubits. Instead quantum volume measures computational ability to indicate the relative complexity of a problem that can be solved by a quantum computer.

NEC is known for its vector processor-powered supercomputers, most notably the Earth Simulator. Typically, NEC’s vector processors have been aimed at numerical simulation and similar workloads, but recently NEC unveiled a platform that makes its latest SX-Aurora Tsubasa supercomputer-class processors usable for artificial intelligence and machine learning workloads.  “The vector […]
