Fundamental limits on state preparation for an open qubit
D. A. Abraamian, L. V. Lokutsievskiy, A. N. Pechen
We analytically determine the ultimate limits of state preparation in two-level open quantum systems driven by coherent control. For a dissipative qubit governed by a GKSL master e…
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. Variou…
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…
Weak coupling limit for quantum systems with unbounded weakly commuting system operators
Ilya Lopatin, Alexander Pechen
This work is devoted to a rigorous analysis of the weak coupling limit (WCL) for the reduced dynamics of an open infinite-dimensional quantum system interacting with electromagneti…
