Quantum Zeno Effect and Light-Dark Periods for a Single Atom
Almut Beige, Gerhard C. Hegerfeldt
The quantum Zeno effect (QZE) predicts a slow-down of the time development of a system under rapidly repeated ideal measurements, and experimentally this was tested for an ensemble…
Atomic Quantum Zeno Effect for Ensembles and Single Systems
Almut Beige, Gerhard C. Hegerfeldt, Dirk G. Sondermann
The so-called quantum Zeno effect is essentially a consequence of the projection postulate for ideal measurements. To test the effect Itano et al. have performed an experiment on a…
State Measurements with Short Laser Pulses and Lower-Efficiency Photon Detectors
Almut Beige, Gerhard C. Hegerfeldt
It has been proposed by Cook (Phys. Scr. T 21, 49 (1988)) to use a short probe laser pulse for state measurements of two-level systems. In previous work we have investigated to wha…
Laser Pulses as Measurements. Application to the Quantum Zeno Effect
Almut Beige, Gerhard C. Hegerfeldt, Dirk G. Sondermann
Short pulses of a probe laser have been used in the past to measure whether a two-level atom is in its ground or excited state. The probe pulse couples the ground state to a third,…
