Abstract

We describe a new method for the decomposition of an arbitrary n qubit operator with entries in mathbb{Z}\[i,frac{1}{sqrt{2}}\], i.e., of the form \(a+bsqrt{2}+i(c+dsqrt{2}\))/{sqrt{2}k}, into Clifford+T operators where nle 2. This method achieves a bound of O(k) gates using at most one ancilla using decomposition into 1- and 2-level matrices which was first proposed by Giles and Selinger.
