Qecsim.jl

Introduction

Qecsim.jl is a Julia package for simulating quantum error correction using stabilizer codes.

NOTE: Qecsim.jl is a ground-up rewrite of the Python package qecsim.

Installation

Qecsim.jl is installed, like any other registered Julia package, using the Julia package manager Pkg:

pkg> add Qecsim  # Press ']' to enter the Pkg REPL mode.

or

julia> using Pkg; Pkg.add("Qecsim")

Examples

See Qecsim.jl documentation for more examples.

Simulation run

julia> using Qecsim, Qecsim.BasicModels, Qecsim.GenericModels

julia> data = qec_run(FiveQubitCode(), BitFlipErrorModel(), NaiveDecoder(), 0.1; max_runs=100);

julia> data
