Abstract

Qiskit pulse allows you low-level control of superconducting qubits. Let's build your own pulse level VQE to get the ground state energy of hydrogen molecules.

Description

The current hybrid quantum algorithm uses parameterized quantum gate as its ansatz to get its optimal result. Like this paper, https://www.nature.com/articles/s41534-021-00493-0, several trials on gate-free VQE have advantages on build a quantum circuit with a short duration compared with quantum gate ansatz. Pulse sequence optimization of the entangled gate is very difficult, so in this project, let's build a custom pulse VQE algorithm that only uses one or two-qubit to compute the ground state energy of hydrogen molecules.

I'm interested in calculating chemical ground state. I want to solve this problem with various algorithms including VQE.(I also searched about QITE.... etc.) Could I join this team?

You are the first attendees, so you can lead this group :) let's wait until next Monday to decide whether gather more or not. We can increase the max number of members and please wait for the organizer's decision.

Hope to wait until next Monday :)
