Coupled Ito equations of continuous quantum state measurement, and estimation
Lajos Diosi, Thomas Konrad, Artur Scherer +1
We discuss a non-linear stochastic master equation that governs the time-evolution of the estimated quantum state. Its differential evolution corresponds to the infinitesimal updat…
Production of heralded pure single photons from imperfect sources using cross phase modulation
Thomas Konrad, Michael Nock, Artur Scherer +1
Realistic single-photon sources do not generate single photons with certainty. Instead they produce statistical mixtures of photons in Fock states and vacuum (noise). We…
Heralded single-photon generation using imperfect single-photon sources and a two-photon-absorbing medium
Thomas Konrad, Artur Scherer, Michael Nock +1
We propose a setup for a heralded, i.e. announced generation of a pure single-photon state given two imperfect sources whose outputs are represented by mixtures of the single-photo…
Evolution of a qubit under the influence of a succession of unsharp measurements
Juergen Audretsch, Lajos Diosi, Thomas Konrad
We investigate the evolution of a single qubit subject to a continuous unitary dynamics and an additional interrupting influence which occurs periodically. One may imagine a dynami…
A New Laser Cooling Concept for Molecular Translational Motion
C. H. Raymond Ooi, Kar Peter Marzlin, Juergen Audretsch
We propose a laser cooling concept for the translational motion of molecules which does not require repeated spontaneous emission by each molecule. The cooling works by repetition…
Singular potentials and absorption problem in Quantum Mechanics
Vladimir D. Skarzhinsky, Juergen Audretsch
We discuss a possible approach to the absorption problem in Quantum Mechanics based on using of singular attractive potentials in the corresponding Schrödinger equations. Possible…
