摘要
在量子信息处理中,量子比特常常处于叠加态,围绕如何隐形传送多比特量子态提出了一种用N个EPR对隐形传送N比特量子态的传输方案,通过N次联合操作实现N比特量子态的传输。其操作为局域操作并且在目前技术条件下可以很容易实现,与单粒子量子态传输相比,多比特量子态可以传送更多信息.
In quantum information, qubits were always in superposition states, so how to teleport a multi - qubit state was an important problem. A scheme was proposed which can teleport N - qubit quantum state by means of Einstein - Podolsky - Rosen (EPR) pairs. All of the operations of the scheme was local and within the reach of current technology. This scheme can teleport more information than using singlet particle quantum state .
