Improving the purity of one- and two-qubit gates by AC fields
Sigmund Kohler, Peter Hänggi
We investigate the influence of AC driving fields on the coherence properties of one- and two-qubit gate operations. In both cases, we find that for suitable driving parameters, th…

Coherence control for qubits
Karen M. Fonseca-Romero, Sigmund Kohler, Peter Hänggi
We study the influence of an external driving field on the coherence properties of a qubit under the influence of bit-flip noise. In the presence of driving, two paradigmatic cases…

Decoherence in resonantly driven bistable systems
Sigmund Kohler, Peter Hänggi
We study dissipative tunneling in a double well potential that is driven close to a resonance between the lowest tunnel doublet and a singlet. While the coherent dynamics can be de…
