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…

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…
