qcircuit – Quantum Circuit Drawing for LaTeX


Originally developed by Bryan Eastin and Steve Flammia while at CQuIC, qcircuit or Qcircuit has become a commonly used tool to draw quantum circuits in LaTeX.

Recently, a group of students have decided to try and re-boot the qcircuit effort in order to enhance functionality and improve ease of use. Check out their GitHub repository to learn more or to help contribute!
