Abstract
- Boson sampling is a sub-universal model used to show quantum speed-up. However, the methods of validation to prove quantum speedup are not robust and accurate. All verification methods involve additional or little studied assumptions. Here, we use the protocols given in the paper [arXiv:2006.03520] to construct a boson sampling experiment using discrete quantum states on IBM quantum computer and verify the fidelity of the output states using heterodyne detection. We demonstrate the protocols for single mode fidelity estimation, multi mode fidelity estimation and a verification protocol using IBMQ "athens" chip. Moreover, we illustrate the use of this verification protocol in the quantum key distribution (QKD) process for estimating the fidelity of different types of encoding-decoding basis. This shows that the verification protocols can be used to enable efficient and reliable certification of highly entangled multi-particle states.<br />Comment: 11 pages , 10 figures and 6 tables
