QC Paulinesia
  My goal in producing this document was to create a collection of qubit circuit identities that are used in Quantum Computing. Mathematicians and Physicists may consider it as being analogous to a Table of Integrals or a Mathematical Handbook such as Gradshteyn-Ryzhik or Abramowitz-Stegun. Computer Programmers may think of it as a scrapbook of code snippets that are elegant, instructive, well documented, and useful. Electronics experts may view it as a compendium of circuits for performing a large assortment of tasks. The vast majority of the circuit identities collected in this work were not discovered for the first time by me, and I take no credit for discovering them. In producing this document, I am acting as a collector, not as a discoverer.
