Pauli exchange errors in Quantum computation |
The Pauli exclusion principle implies that fault-tolerant quantum computation requires the ability to correct a special type of two-qubit error which is equivalent to exchanging the qubits. We give an explicit (non-additive) 9-bit code which can handle both Pauli exchange errors and all one-bit errors.
