Perfect Zeno-like effect through imperfect measurements at a finite frequency
arXiv:1410.3826 · doi:10.1103/PhysRevA.91.022106
Abstract
The quantum Zeno effect is usually thought to require infinitely frequent and perfect projective measurements to freeze the dynamics of quantum states. We show that perfect freezing of quantum states can also be achieved by more realistic non-projective measurements performed at a finite frequency.
