Teleportation of an unknown bipartite state via non-maximally entangled two-particle state

In this paper a new scheme for teleporting an unknown entangled state of two particles is proposed. To weaken the requirement for the quantum channel, without loss of generality, two communicators only share a non-maximally entangled two-particle state. Teleportation can be probabilistically realized if sender performs Bell-state measurements and Hadamard transformation and receiver introduces two auxiliary particles, operates C-not operation, single-qubit measurements and appropriate unitary transformations. The probability of successful teleportation is determined by the smaller one among the coefficients＇ absolute values of the quantum channel.

我们建议为与二部分分成三部分的 qutrit 州的纠缠的未知分成三部分的 qutrit 的控制概率的远距传物的一个协议作为量隧道纠缠了状态。在三维的 Hilbert 空格与概括 qutrit 钟基础测量，概括 qutrit π-state 测量和概括 Hadamard 操作符联系了，被发现那远距传物。我们概括协议因为未知 k 粒子 qudit 的控制概率的远距传物纠缠了状态，州的多粒子 qudit 纠缠了，分成三部分的 qudit 作为量隧道纠缠了状态。我们也计算在两个盒子中要求的古典通讯费用。
