Features:

  • Tools to compute signaling correlations and polytopes.
  • Methods to certify the signaling dimension of black-box systems.
  • A catalog of Bell inequalities for witnessing signaling dimension.

Overview

The advent of quantum technology requires new figures of merit to compare the performance of quantum and classical systems. The signaling dimension quantifies the classical simulation cost of black-box devices. That is, it specifies the minimum amount of noiseless, classical communication needed to exactly simulate the input-output statistics of the device in question. The signaling dimension is discussed in greater detail in the Background section of this documentation.

Quick Start

julia> using Pkg; Pkg.add("SignalingDimension")
  • Add BellScenario.jl and QBase.jl dependencies:
julia> using Pkg; Pkg.add("BellScenario")
julia> using Pkg; Pkg.add("QBase")
