Phys. Rev. A 76, 032311 (2007) [4 pages]Remote one-qubit information concentration and decoding of operator quantum error-correction codesReceived 11 July 2007; published 11 September 2007 We propose the general scheme of remote one-qubit information concentration. To achieve the task, the Bell-correlated mixed states are exploited. In addition, the nonremote one-qubit information concentration is equivalent to the decoding of the quantum error-correction code. Here we propose how to decode the stabilizer codes. In particular, the proposed scheme can be used for the operator quantum error-correction codes. The encoded state can be recreated on the errorless qubit, regardless how many bit-flip errors and phase-flip errors have occurred. © 2007 The American Physical Society URL:
