Error Mitigated Non-Orthogonal Quantum Eigensolver Using Shadow Tomography

ORAL

Abstract

We present a novel integration of shadow tomography with the non-orthogonal quantum eigensolver (NOQE) algorithm [PRX Quantum 4, 030307] that significantly reduces the experimental resources required to characterize electronic energies. Additionally, we incorporate error mitigation techniques to suppress both gate and quantum measurement (shot) noise, thereby enhancing the accuracy of energy estimation. We show that this protocol offers a scalable and noise-resilient approach for calculating electronic states and their energies.

Publication: We have one publication that serves as preliminary work for this research [1], and we are currently preparing a manuscript based on this work<br>[1] Ren H, Zhang Y, Zheng Z, et al.
