Quantum Technology Initiative Journal Club

Thursday 30 May 2024, 16:00 → 17:00 Europe/Zurich

513/R-070 - Openlab Space (CERN)

Alice Barthe (Leiden University (NL)), Michele Grossi (CERN), Su Yeon Chang (EPFL - Ecole Polytechnique Federale Lausanne (CH))

Weekly Journal Club meetings organised in the framework of the CERN Quantum Technology Initiative (QTI) to present and discuss scientific papers in the field of quantum science and technology. The goal is to help researchers keep track of current findings and walk away with ideas for their own research. Some previous knowledge of quantum physics would be helpful, but is not required to follow the talks.

To propose a paper for discussion, contact: michele.grossi@cern.ch

CERN QTI Journal CLUB: Perturbative Quantum Simulations and VQE

Convener: Dr Michele Grossi (CERN)

Perturbative Quantum Simulations and VQE

Abstract:
In this talk, I will present the ideas of utilizing the Dyson perturbation theory in simulations on the quantum computer, and how to turn these ideas into VQE-like computational strategies with the help of the Variational Perturbation Theory (VPT). The main reference for the Perturbative Quantum Simulations is https://arxiv.org/abs/2106.05938, and for the introduction to VPT, one can look at https://pubs.aip.org/aip/jmp/article/20/7/1398/749202/Summation-of-divergent-series-by-order-dependent

Speaker: Dr Vasily Sazonov
