Quantum Computing, Fault Tolerance, Error Correction, Logical Qubits.
logical qubit, once again, the 50-qubit limit comes into play. So if, for example, 57 or 65 physical qubits are needed to simulate a single logical qubit, then by definition the quantum volume metric would not be practical due to the need to fully simulate more than 50 physical qubits. The 50 qubit
