Complete disentanglement by partial pure dephasing
Katarzyna Roszak, Pawel Machnikowski
We study the effect of pure dephasing on the entanglement of a pair of two-level subsystems (qubits). We show that partial dephasing induced by a super-Ohmic reservoir, correspondi…

Change of decoherence scenario and appearance of localization due to reservoir anharmonicity
Paweł Machnikowski
Although coupling to a super-Ohmic bosonic reservoir leads only to partial dephasing on short time scales, exponential decay of coherence appears in the Markovian limit (for long t…

Optimal strategy for a single-qubit gate and trade-off between opposite types of decoherence
Robert Alicki, Michal Horodecki, Pawel Horodecki +3
We study reliable quantum information processing (QIP) under two different types of environment. First type is Markovian exponential decay, and the appropriate elementary strategy…
