Abstract

These lecture notes survey some joint work with Samson Abramsky as it was presented by me at several conferences in the summer of 2005. It concerns `doing quantum mechanics using only pictures of lines, squares, triangles and diamonds'. This picture calculus can be seen as a very substantial extension of Dirac's notation, and has a purely algebraic counterpart in terms of so-called Strongly Compact Closed Categories (introduced by Abramsky and I in <a href="/abs/quant-ph/0402130">quant-ph/0402130</a> and 4) which subsumes my Logic of Entanglement <a href="/abs/quant-ph/0402014">quant-ph/0402014</a>. For a survey on the `what', the `why' and the `hows' I refer to a previous set of lecture notes <a href="/abs/quant-ph/0506132">quant-ph/0506132</a>. In a last section we provide some pointers to the body of technical literature on the subject.
