Quantum Zeno Effect |
In General
> s.a. measurements and types of measurements.
* Idea: (Also called watchdog effect)
A continuously–or almost–watched particle (unstable system) never decays,
because the state keeps collapsing back to the original state upon observation.
* Quantum Zeno subspaces: Interaction
with another system at thermal equilibrium induces the partitioning of the Hilbert
space of a quantum system.
* Quantum Zeno dynamics: The time
evolution within the projected "quantum Zeno subspace" defined by the
measurement.

evolution that results from repeated measurements on a quantum system.

Variations
* Anti-Zeno effect: A perpetual
observation leads to an immediate disappearance of an unstable system.
* Spatial Zeno effect: The
repetition of the same experiment over the time axis is replaced by simultaneous
performances of the same experiment in a number of identical independent
non-overlapping regions of space.
