The quantum Zeno effect appears to be real - but its interpretation is still hotly debated. And perhaps some of this is just semantic - for example, ...
While the quantum Zeno effect uses repeated measurements to freeze a quantum system in place (or at least slow its evolution from one state to another), it is also possible to do the opposite and use ...
Quantum Zeno Effect: The suppression of quantum evolution through frequent measurements. Quantum Zeno Dynamics: The controlled, constrained evolution of a quantum system under continuous or ...
The “enhanced” decay is the result of the Quantum Anti-Zeno Effect. Time your measurements just right and you can actually push a system to decay faster than it would if it were unobserved.
This so-called "Quantum Zeno effect", named for a Greek philosopher, derives from a proposal in 1977 by E. C. George Sudarshan and Baidyanath Misra at the University of Texas, ...
In effect, the process of repeated measurement prevents the photon decaying from a 0 to a 1. That’s the quantum zeno effect, sometimes also called the watched-pot-never-boils effect.
But the quantum Zeno effect does show that, at very, very tiny scales, you might be able to stop time. You just have to be a master at staring contests. Learn Something New Every Day.

It is now also assumed that the quantum Zeno effect could play a role in the magnetic sense of birds. So even 2,500 years after the Greek philosopher’s thought experiments, Zeno’s paradoxes ...
