基于4粒子纠缠态的未知3粒子态概率量子隐形传态
Probabilistic teleportation of an unknown three-particle state via a four-qubit entangled state
摘要
Abstract
By using a four-qubit non-maximally entangled state as quantum channel, under the condition of whose coefficients were unknown, a scheme of an unknown three-partical state's teleportation was proposed. In the process of transmission the sender performed Bell state measurements to two pairs of particles and released finding,then completed a quantum controlled Hadamard gate operation and Bell state measurement to one of four particles, finally released finding via classical channel. By introducing two ancillary qubits, adopting a Controlled-Not gate and constructing a unitary transformation properly, the probabilistic teleportation of three- particle entangled state could be accomplished.关键词
