IBM and Five Universities Show Quantum Chip Holding Coherence for 5,000 Operations
A superconducting quantum processor can now hold its coherence long enough to run roughly 5,000 consecutive two-qubit operations plus 5,000 measurement-and-reset cycles without collapsing. That is the headline finding from IBM and five US academic institutions in Nature Physics — and it points to an error-correction mechanism that seems to grow stronger, not weaker, as … Read more
