Proof-of-principle experimental demonstration of quantum gate verification

Maolin Luo, Xiaoqian Zhang, Xiaoqi Zhou

To employ a quantum device, the performance of the quantum gates in the device needs to be evaluated first. Since the dimensionality of a quantum gate grows exponentially with the…

Direct Fidelity Estimation of Quantum States using Machine Learning

Xiaoqian Zhang, Maolin Luo, Zhaodi Wen +4

In almost all quantum applications, one of the key steps is to verify that the fidelity of the prepared quantum state meets expectations. In this Letter, we propose a new approach…
