Exciton-LO-phonon dynamics in InAs/GaAs quantum dots: Effects of zone-edge phonon damping
Pawel Machnikowski, Lucjan Jacak
The dynamics of an exciton-LO-phonon system after an ultrafast optical excitation in an InAs/GaAs quantum dot is studied theoretically. Influence of anharmonic phonon damping and i…
Fast control of quantum states in quantum dots: limits due to decoherence
Pawel Machnikowski, Lucjan Jacak
We study the kinetics of confined carrier-phonon system in a quantum dot under fast optical driving and discuss the resulting limitations to fast coherent control over the quantum…
Damping of Rabi oscillations in quantum dots due to lattice dynamics
Pawel Machnikowski, Lucjan Jacak
We show that the interaction between carriers confined in a quantum dot and the surrounding lattice under external driving of carrier dynamics has a dynamical, resonant character.…
Resonant nature of phonon-induced damping of Rabi oscillations in quantum dots
Pawel Machnikowski, Lucjan Jacak
Optically controlled coherent dynamics of charge (excitonic) degrees of freedom in a semiconductor quantum dot under the influence of lattice dynamics (phonons) is discussed theore…
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…
