Elementary proofs of two theorems involving arguments of eigenvalues of a product of two unitary matrices
<p>Abstract</p> <p>We give elementary proofs of two theorems concerning bounds on the maximum argument of the eigenvalues of a product of two unitary matrices--one by Childs et al. [J. Mod. Phys. <b>47</b>, 155 (2000)] and the other one by Chau [Quant. Inf. Comp. <b&...
