Continuous variable remote state preparation
Z. Kurucz, P. Adam, Z. Kis +1
We extend exact deterministic remote state preparation (RSP) with minimal classical communication to quantum systems of continuous variables. We show that, in principle, it is poss…
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…
Measuring the Density Matrix by Local Addressing
Z. Kis, S. Stenholm
We introduce a procedure to measure the density matrix of a material system. The density matrix is addressed locally in this scheme by applying a sequence of delayed light pulses.…
Enhanced Nonlinear Generation in a Three-Level Medium with Spatially Dependent Coherence
E. Paspalakis, Z. Kis
We consider a method for efficient parametric generation of a laser pulse. A single laser field is injected to a three-level medium which has two lower states and one excited state…
Qubit Rotation by STIRAP
Z. Kis, F. Renzoni
We introduce a novel procedure for qubit rotation, alternative to the commonly used method of Rabi oscillations of controlled pulse area. It is based on the technique of Stimulated…
