This LaTeX package allows quickly drawing quantum circuits. It bridges the gap between the two groups of packages that already exist: those that use a logic-oriented custom language, which is then translated into TeX by means of an external program; and the pure TeX versions that mainly provide some macros to allow for an easier input. yquant introduces a logic oriented language and thus brings the best of both worlds together. It builds on and interacts with TikZ, which brings an enourmous flexibility for customization of individual circuit.
