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…
Phenomenon of a stronger trapping behaviour in -type quantum systems with symmetry
Boris Volkov, Anastasia Myachkova, Alexander Pechen
, , (ladder), and other three-level quantum systems with one forbidden transition (referred here as -type systems) play an important role in quantum physics. Various a…
Incoherent GRAPE (inGRAPE) for optimization of quantum systems with environmentally assisted control
Vadim Petruhanov, Alexander Pechen
In this work, we review several results on development and application of incoherent version of GRAPE (Gradient Ascent Pulse Engineering) approach, inGRAPE, to optimization for ope…
Time-optimal state transfer for an open qubit
L. V. Lokutsievskiy, A. N. Pechen, M. I. Zelikin
Finding minimal time and establishing the structure of the corresponding optimal controls which can transfer a given initial state of a quantum system into a given target state is…
Optimal remote restoring of quantum states in communication lines via local magnetic field
E. B. Fel'dman, A. N. Pechen, A. I. Zenchuk
Optimal state transport across spin chains, which are proposed as quantum wires for information transfer in solid state quantum architectures, is an important topic for quantum tec…
