Investigating the variance increase of readout error mitigation through\n classical bit-flip correction on IBM and Rigetti quantum computers

2021 · arXiv (Cornell University)

Readout errors are among the most dominant errors on current noisy\nintermediate-scale quantum devices. Recently, an efficient and scaleable method\nfor mitigating such errors has been developed, based on classical bit-flip\ncorrection. In this talk, we compare the …

Physics-Informed Bayesian Optimization of Variational Quantum Circuits

2024 · arXiv (Cornell University)

In this paper, we propose a novel and powerful method to harness Bayesian optimization for Variational Quantum Eigensolvers (VQEs) -- a hybrid quantum-classical protocol used to approximate the ground state of a quantum Hamiltonian. Specifically, …
