QuantumExpanders is a   Julia Language   package for constructing quantum Tanner codes. To install QuantumExpanders, please open Julia's interactive session (known as REPL) and press the ] key in the REPL to use the package mode, and then type:

pkg> add https://github.com/QuantumSavory/QuantumExpanders.jl.git

• gen_code - Create a CSS code out of two Tanner codes 𝒞ᶻ and 𝒞ˣ, each constructed out of two related graphs 𝒢₀□, 𝒢₁□, the graphs build out of a Cayley complex, which itself was based on a group G=SL₂qⁱ and two generator sets A and B. For consistency of indexing of "qubits" ≈ "graph edges" ≈ "squares" and "local bits" ≈ "generator pairs" we have the edge_*_idx maps.
