Title：Similarity Invariants of Geometric Operators
Abstract: In 1978, I.M.Cowen and R.G .Douglas introduced a class of geometric operators in a Grassmann manifold. In their influential paper they give a unitary invariant involving geometric ideas, such as...
Abstract: Quantum circuit is the standard and powerful tool to describe the process of quantum computation. It is important to simplify or to classically simulate quantum circuits. Here we report the recent progress on the...
