IBM unveils a bold new ‘quantum error mitigation’ strategy

IBM today announced a new strategy for the implementation of several “error mitigation” techniques designed to bring about the era of fault-tolerant quantum computers. Up front: Anyone still clinging to the notion that quantum circuits are too noisy for useful computing is about to be disillusioned. A decade ago, the idea of a working quantum computing system seemed far-fetched to most of us. Today, researchers around the world connect to IBM’s cloud-based quantum systems with
