The breakthrough Zeno aftereffect is a name coined by George Sudarshan and Baidyanath Misra of the University of Texas in 1977 in their assay of the bearings in which an ambiguous particle, if empiric continuously, will never decay.1 One can about "freeze" the change of the arrangement by barometer it frequently abundant in its (known) antecedent state. The acceptation of the appellation has back expanded, arch to a added abstruse analogue in which time change can be suppressed not alone by measurement: the breakthrough Zeno aftereffect is the abolishment of unitary time change acquired by breakthrough decoherence in breakthrough systems provided by a array of sources: measurement, interactions with the environment, academic fields, and so on.2 As an bulge of abstraction of the breakthrough Zeno effect, it has become bright that applying a alternation of abundantly able and fast pulses with adapted agreement can aswell decouple a arrangement from its decohering environment.3
The name comes from Zeno's arrow absurdity which states that, back an arrow in flight is not apparent to move during any individual instant, it cannot possibly be affective at all.4
An beforehand abstract analysis of this aftereffect of altitude was appear in 1974 by Degasperis et al. 5 and Alan Turing declared it in 1954:6
resulting in the beforehand name Turing paradox. The abstraction is independent in the aboriginal plan by John von Neumann, sometimes alleged the abridgement postulate.7
According to the abridgement postulate, anniversary altitude causes the wavefunction to "collapse" to a authentic eigenstate of the altitude basis. In the ambience of this effect, an "observation" can artlessly be the assimilation of a particle, after an eyewitness in any accepted sense. However, there is altercation over the estimation of the effect, sometimes referred to as the "measurement problem" in traversing the interface amid diminutive and macroscopic.89
Closely accompanying (and sometimes not acclaimed from the breakthrough Zeno effect) is the babysitter effect, in which the time change of a arrangement is afflicted by its connected coupling to the environment.1011
