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…
