Abstract

In this work, we propose a probabilistic teleportation protocol to teleport a single qubit via three-qubit W-states using two-qubit measurement basis. We show that for the proper choice of the state parameter of the resource state, it is possible to make success probability of the protocol very high. We deduce the condition for the successful execution of our teleportation protocol and this gives us new class of three-qubit W-states which act as a resource state. We have constructed operators that can be used to verify the condition of teleportation in experiment. This verification is necessary for the detection of whether the given three-qubit state is useful in our teleportation protocol or not. Further we quantify the amount of entanglement contained in the newly identified shared W-class of states. Moreover, we show that the W-class of shared state used in the teleportation protocol can be prepared using NMR set up.

单量子位的概率隐形传态：发掘新的W级国家

摘要

在这项工作中，我们提出了一种概率传送协议，该协议使用两个量子位的测量基础，通过三个量子位的W状态来传送单个量子位。我们表明，为了正确选择资源状态的状态参数，可以使协议的成功概率非常高。我们推论了成功执行我们的隐形传态协议的条件，这为我们提供了一种新的三量子位W状态，可以充当资源状态。我们构造了可用于验证实验中隐形传送条件的运算符。该验证对于检测给定的三比特状态是否对我们的隐形传态协议有用是必需的。此外，我们量化了新识别的共享W类状态中包含的纠缠量。此外，
