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…
"Which path" decoherence in quantum dot experiments
K. Roszak, P. Machnikowski
We analyze and interpret recent optical experiments with semiconductor quantum dots. We derive a quantitative relation between the amount of information transferred into the enviro…
Manifestation of fundamental quantum complementarities in time-domain interference experiments with quantum dots: A theoretical analysis
P. Machnikowski
A theoretical analysis is presented showing that fundamental complementarity between the particle-like properties of an exciton confined in a semiconductor quantum dot and the abil…
