Quantum Technology Initiative Journal Club

Thursday 5 Dec 2024, 16:00 → 17:00 Europe/Zurich

513/R-070 - Openlab Space (CERN)

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

TITLE: Boosting ground states preparation with double-bracket quantum algorithms (part 2)
SUBTITLE: Interfacing DBQAs with other techniques

PAPER REF 1: https://arxiv.org/abs/2206.11772 (DBQA)
PAPER REF 2: https://arxiv.org/abs/2408.03987 (Ground state preparation)

ABSTRACT:
We discuss the cost of implementing double-bracket quantum algorithms on a device and the idea of interfacing this technique with other methods. In this case, the combined usage of DBQAs and VQEs allows to boost che ground state preparation of target Hamiltonians while keeping under control the number of gates required to compile the whole procedure. After a brief theoretical introduction, we move to an hands-on session to apply this procedure in practice.
