Quantum Computing, Fault Tolerance, Error Correction, Logical Qubits.
five years Once we have machines with 32 to 128 near-perfect physical qubits, then the big question becomes when we will see fault-tolerant quantum computers with 32 to 128 logical qubits. Using a physical to logical qubit ratio of 65 (from an IBM paper), that would imply: 32 logical qubits require
