Exploring MBL via VVQE & BBA

A Qiskit Summer Jam 2020 hackathon project

👉 Presentation
📓Notebooks: Entanglement Entropy Plots | BBA pure state test | BBA mixed state test
📊 Data: ED | VVQE | BBA

Physics Background

In the classical world we are used to matter thermally equilibrating with its environment, like a hot cup of coffee cooling down, but in the quantum world there are phases of matter known as many-body localized (MBL) phases that do not equilibrate, like a never-cooling cup of coffee. In this hackathon, we wanted to study MBL using quantum computers.

Implementation

We implement two quantum algorithms using Qiskit

• VVQE - Variance Variationial Quantum Eigensolver
• Entropy Measurement [1]
  • Swap Test
  • BBA

This opens a new path forward to study MBL with quantum computers!

Requirements

This was built using Qiskit version 0.19.6. To read and analyze some of the data we also recommend you use pandas and Jupyter notebooks.

Tests

Use pytest to run tests
