qxlib

qxlib is an official alternative installation entry point for Qubex, maintained by Akinori Machino. It installs Qubex and its companion libraries through normal Python package dependencies, without copying their code or introducing another import namespace.

Install

This first release is a prerelease for validating Qubex 1.5.0rc4. Use a fresh Python 3.10+ environment:

pip install "qxlib==1.5.0rc4"

For the QuEL-1 hardware backend on Linux:

pip install "qxlib[backend]==1.5.0rc4"

qxlib[quel1] is an equivalent explicit extra. For QuEL-3 support:

pip install "qxlib[quel3]==1.5.0rc4"

Each extra forwards to the corresponding Qubex extra at the same version. Hardware operation requires separate device configuration and authorization.

Use

Use the existing Qubex Python imports:

import qubex
from qubex.simulator import QuantumSimulator, QuantumSystem, Transmon

There is no import qxlib module. The qxlib distribution is the installer entry point; qubex, qxcore, qxpulse, qxschema, qxsimulator, and qxvisualizer provide the implementation. Installing qxlib and qubex at the matching version in one environment does not duplicate those modules.

For rc3 or earlier installations, use a fresh environment or remove the old companion distributions before upgrading, as explained in the Qubex migration guide.

This distribution is maintained as a working dependency-based installer for Qubex. Its dependency pins and forwarded extras are part of its release contract.
