Engineering mixed states in a degenerate four-state system
Attila Karpati, Zsolt Kis, Peter Adam
A method is proposed for preparing any pure and a wide class of mixed quantum states in the decoherence-free ground-state subspace of a degenerate multilevel lambda system. The sch…
Stimulated Raman Adiabatic Passage (STIRAP) Among Degenerate-Level Manifolds
Zsolt Kis, Attila Karpati, Bruce W. Shore +1
We examine the conditions needed to accomplish stimulated Raman adiabatic passage (STIRAP) when the three levels (g, e and f) are degenerate, with arbitrary couplings contributing…
Adiabatic creation of coherent superposition states via multiple intermediate states
A. Karpati, Z Kis
We consider an adiabatic population transfer process that resembles the well established stimulated Raman adiabatic passage (STIRAP). In our system, the states have nonzero angular…
Competitive stochastic noises in coherently driven two-level atoms and quantum interference
P. Adam, A. Karpati, W. Gawlik +1
A system of coherently-driven two-level atoms is analyzed in presence of two independent stochastic perturbations: one due to collisions and a second one due to phase fluctuations…
Quantum trajectory approach to stochastically-induced quantum interference effects in coherently-driven two-level atoms
A. Karpati, P. Adam, W. Gawlik +2
Stochastic perturbation of two-level atoms strongly driven by a coherent light field is analyzed by the quantum trajectory method. A new method is developed for calculating the res…
