Authenticated teleportation and verification in a noisy network
Physical Review A ( IF 2.6 ) Pub Date : 
Anupama Unnikrishnan, Damian Markham

Authenticated teleportation aims to certify the transmission of a quantum state through teleportation, even in the presence of an adversary. This scenario can be pictured in terms of an untrusted source distributing a Bell state between two parties who wish to verify it using some simple tests. We propose a protocol that achieves this goal in a practical way, and analyse its performance and security when the parties have noisy measurement devices. Further, we model a realistic experimental scenario where the state is subject to noise. We finally apply our analysis to the verification of graph states with noisy measurement devices.

嘈杂网络中经过身份验证的传送和验证

经过身份验证的隐形传态的目的是即使在存在对手的情况下,也可以通过隐形传态来证明量子态的传输。可以用一种不可靠的来源来描述这种情况,该来源在希望使用一些简单测试进行验证的各方之间分配贝尔状态。我们提出一种协议,以一种实用的方式实现此目标,并在当事方拥有嘈杂的测量设备时分析其性能和安全性。此外,我们对状态受噪声影响的实际实验场景进行建模。最后,我们将分析应用于带有噪声的测量设备对图形状态的验证。
