- btian 9y agoSame as classical computers, what makes Intel i7 superior to AMD Ryzen 7? One that can perform a computation task fastest with least energy would clearly be superior to another.
- ajdlinux 9y agoIBM talks about a metric called "quantum volume" that combines number of qubits with error rate to summarise useful computing performance.
