PAREC method for quantum error correction

A general quantum error correction method is presented which is capable of correcting coherent errors originating from static residual inter-qubit couplings in a quantum computer. It is based on a randomisation of static imperfections in a many-qubit system by the repeated application of Pauli operators, which change the computational basis. This Pauli-Random-Error-Correction (PAREC)-method eliminates coherent errors produced by static imperfections and increases significantly the maximum time over which realistic quantum computations can be performed reliably. Furthermore, it does not require redundancy so that all physical qubits involved can be used for logical purposes. We expect that in the future this general-purpose code will be used to improve the accuracy of quantum computation.
