利用量子比特的最大纠缠态远程制备量子点

Remote Preparation of a Qudit Using Maximally Entangled States of Qubits

Chang-shui Yu, He-shan Song, Yahong Wang

摘要:

利用二能级Einstein-Podolsky-Rosen态,可以精确地或概率地将量子比特的已知量子纯态远程制备到量子比特的粒子群上。我们提出了一个协议,这种远程状态的准备。我们主要研究了赤道态和实希尔伯特空间态系综的远程制备。特别地,实Hilbert空间中的一类量子态被证明是远程可信准备的,而不受输入空间维数的限制。

英文摘要:

Known quantum pure states of a qudit can be remotely prepared onto a group of particles of qubits exactly or probabilistically with the aid of two-level Einstein-Podolsky-Rosen states. We present a protocol for such kind of remote state preparation. We are mainly focused on the remote preparation of the ensembles of equatorial states and those of states in real Hilbert space. In particular, a kind of states of qudits in real Hilbert space have been shown to be remotely prepared in faith without the limitation of the input space dimension.
