Four decades after three Berkeley physicists made quantum mechanics visible to the naked eye, the fragile phenomenon they captured in a superconducting circuit has matured into the architectural foundation of a new kind of computing. What began as a proof that the quantum world need not remain invisible has become, through thousands of incremental refinements in materials and control, a field no longer asking whether quantum computers can work — but how to make them work better. The boundary between the possible and the practical is narrowing, not by sudden revelation, but by the patient accum
