k n are shown by using elementary methods. More generally, it is shown that the renormalized truncated Haar unitaries converge to a Gaussian random matrix in distribution. truncated Haar unitary, method of moments, trace of powers.
timal control for generating quantum gates in open dissipative systems , " " Optimal control of quantum gates and suppression of decoherence in a system of interacting two-level particles, " Abstract—In this technical note, we study the problem of parameter estimation for quantum channels, which are (completely positive) maps acting on quantum states. We… (More)
