Abstract Research data is an essential part of research and almost every publication in chemistry. The data itself can be valuable for reuse if sustainably deposited, annotated and archived. Thus, it is important to publish …

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 …

Fermionic wave packet scattering: a quantum computing approach

2023 · arXiv (Cornell University)

Quantum computing provides a novel avenue towards simulating dynamical phenomena, and, in particular, scattering processes relevant for exploring the structure of matter. However, preparing and evolving particle wave packets on a quantum device is a …

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, …
