High-fidelity tracking of the evolution of multilevel quantum states
Yu. I. Bogdanov, N. A. Bogdanova, Yu. A. Kuznetsov +1
The method of quantum tomography, which allows us to track with high accuracy the evolution of multilevel quantum systems (qudits) in Hilbert spaces of various dimensions is presen…

Quantum tomography based on principles of completeness, adequacy and fidelity
Yu. I. Bogdanov, N. A. Bogdanova, B. I. Bantysh +2
In this report we present a general approach for estimating quantum circuits by means of measurements. We apply the developed general approach for estimating the quality of superco…
