Diverse efficiency of observable optimization for four-level quantum systems with higher-order traps
Alexander Pechen, Boris Volkov
In this work, we perform an analytical and numerical analysis of quantum landscapes for controlling special four-level quantum systems for which we prove that the null control is a…

Control landscapes for high-fidelity generation of C-NOT and C-PHASE gates with coherent and environmental driving
Alexander N. Pechen, Vadim N. Petruhanov, Oleg V. Morzhin +1
High fidelity generation of two-qubit gates is important for quantum computation, since such gates are components of popular universal sets of gates. Here we consider the problem o…
