利用不完全纠缠实现概率非局域门操作

Probabilistic nonlocal gate operation via imperfect entanglement

Jingak Jang, Jinhyoung Lee, M. S. Kim, Y. -J. Park

摘要:

非定域门操作是基于共享一对辅助量子比特的完美纠缠。当辅助对部分纠缠时,门操作的效率下降。使用一般的变换,我们设计概率非局部门,它执行非局部操作时,辅助对只有部分纠缠决定性。我们表明,一个受控的净化协议可以实现的概率非局部操作。

英文摘要:

Nonlocal gate operation is based on sharing an ancillary pair of qubits in perfect entanglement. When the ancillary pair are partially entangled, the efficiency of the gate operation drops. Using general transformations, we devise probabilistic nonlocal gates, which perform the nonlocal operation conclusively when the ancillary pair are only partially entangled. We show that a controlled purification protocol can be implemented by the probabilistic nonlocal operation.
