z-quantum-vqe

What is it?

z-quantum-vqe is a module with basic implementation of Variational Quantum Eigensolver (VQE) to be used with Orquestra – a platform for performing computations on quantum computers developed by Zapata Computing.

Usage

Workflow

In order to use z-quantum-vqe in your workflow, you need to add it as an import in your Orquestra workflow:

imports:
- name: z-quantum-vqe
  type: git
  parameters:
    repository: "git@github.com:zapatacomputing/z-quantum-vqe.git"
    branch: "main"

and then add it in the imports argument of your step:

- name: my-step
  config:
    runtime: python3
    imports: [z-quantum-vqe]

Once that is done you can:

• use tasks which import zquantum.vqe in the python code (see below).

Python

Here's an example how to do use methods from z-quantum-vqe in a Python task:

from zquantum.vqe.ansatz import build_circuit_template
ansatz = build_circuit_template(
              ansatz_type='Singlet UCCSD',
              n_mo=1,
              n_alpha=1,
              n_beta=1,
              transformation='Jordan-Wigner')

Even though it's intended to be used with Orquestra, you can also use it as a standalone python module. In order to install it run pip install . from the src/ directory.

Development and contribution

You can find the development guidelines in the z-quantum-core repository.

Running tests

In order to run tests please run pytest . from the main directory.
