Quantum Computing, Nisq, Qubit Fidelity, Quantum Error Correction, Near Perfect Qubits.
Near-Perfect Large-Scale Quantum devices. More than a few hundred to thousands or even millions of near-perfect qubits — with qubit reliability in the range 99.9% to 99.9999%. FTSSQ — Fault-Tolerant Small-Scale Quantum devices. Under 50 or so logical qubits. Perfect computation, but insufficient
