| 英文摘要 | This Letter presents a three-qubit quantum error correction scheme that adopts the optimal universal 1 --> 2 quantum cloning transformation U to encode an unknown state \phi>\0>\0> into a three-qubit state U\phi>\0>\0>. The encoded state could protect against collective decoherences that any two qubits in a three-qubit system are affected by either phase error or bit flip error, or simultaneously affected by both of them. To recover the original unknown state, we just need to perform a Bell measurement on the first two qubits and rotate the third qubit along a suitable axis. Specially, our scheme for the first time shows that quantum cloning is useful for quantum error correction. (C) 2004 Elsevier B.V. All rights reserved. |
