MAST - Magic State Injection Augmented Stabilizer Tensor Networks

This library forms the basis of the work in arXiv:2411.12482 and includes the following simulators

  1. A standard Matrix Product State (MPS) simulator
  2. A stabilizer tableau simulator
  3. A Stailizer Tensor Network (STN) simulator (based off Phys. Rev. Lett (133) 230601)
  4. A Magic Injected Stabilizer Tensor Network (MAST) simulator (as introduced in arXiv:2411.12482)

Installation

Before you get started, you will need the following instaled on your machine

  1. Rust
  2. Python 3 and pip
  3. maturin (you can install this by running pip install maturin)
  4. OpenBLAS

You can then clone the repository and from that directory you can run pip install . to install the Python front-end.

Basic use

You can interact with all of the MPS, STN and MAST simulators in largely the same way.

Here's a basic example

import mast
N = 50 # Number of qubits
t = 30 # Number of T gates
max_bond = 0 # Maximum bond dimension -- if 0 then no maximum is set
circ = mast.MagicInjectedStn(N, t, max_bond)
circ.h(0)
circ.cx(0,30)
circ.t(30)
# ... and so on ... #
# Before you can measure observables from MAST you must project the magic register
circ.project_magic()
# Now you can project the data register or get expectation values
circ.project(0)
