论文摘要
我们提出了一种直接操纵任意量子的方法，而无需交换任何粒子。这包括作为应用程序，由远程古典鲍勃在爱丽丝在爱丽丝的任意量子状态的无交换制备。结果，我们能够提出一项协议，该协议允许一个方直接通过合适的程序直接颁布远程第二方未知量子的任何计算交换。此外，我们展示了如何将其用于对通用双Quition门的无交换控制，从而打开了直接在可编程量子电路上远程制定任何所需算法的可能性。
We present a way of directly manipulating an arbitrary qubit, without the exchange of any particles. This includes as an application the exchange-free preparation of an arbitrary quantum state at Alice by a remote classical Bob. As a result, we are able to propose a protocol that allows one party to directly enact, by means of a suitable program, any computation exchange-free on a remote second party's unknown qubit. Further, we show how to use this for the exchange-free control of a universal two-qubit gate, thus opening the possibility of directly enacting any desired algorithm remotely on a programmable quantum circuit.
