1302.4690 (Simeon Sauer et al.)

Optimal coherent control to counteract dissipation    [PDF]

Simeon Sauer, Clemens Gneiting, Andreas Buchleitner
We study to what extent the detrimental impact of dissipation on quantum properties can be compensated by suitable coherent dynamics. To this end, we develop a general method to determine the control Hamiltonian that optimally counteracts a given dissipation mechanism, in order to sustain the desired property, and apply it to two exemplary target properties: the coherence of a decaying two-level system, and the entanglement of two qubits in the presence of local dissipation.
