tranzor 0.1.0

Transversal Clifford logical circuit generator for color code.

Tranzor

WARNING: This project is a preliminary mock-up and has not been extensively tested, so it may encounter bugs.

Tranzor is a generator for transversal Clifford logical circuits using the color code.

Given a logical-level circuit represented in stim, tranzor compiles each qubit in the circuit into a logical qubit encoded with the superdense color code, and each gate into a transversal gate supported by the color code. A syndrome extraction round is explicitly represented using the I instruction in the circuit.

Installation

pip install tranzor

Examples

S Gate

import stim
from tranzor import SuperDenseColorCode, compile_circuit

logical_circuit = stim.Circuit("""
QUBIT_COORDS(0, 0) 0
RX 0
TICK
I 0
TICK
S_DAG 0

TICK
MX 0
OBSERVABLE_INCLUDE(0) rec[-1]

color_code = SuperDenseColorCode(d=3)
out = compile_circuit(logical_circuit, color_code)

compiles to the following Crumble circuit.
