In every parameter-estimation experiment, the final measurement or the postprocessing
incurs a cost. Postselection can improve the rate of Fisher information (the average …

The average result of a weak measurement of some observable A can, under postselection
of the measured quantum system, exceed the largest eigenvalue of A. The nature of weak …

A bstract In this paper, we introduce a new quantity called SVD entanglement entropy. This
is a generalization of entanglement entropy in that it depends on two different states, as in …

Two topics, evolving rapidly in separate fields, were combined recently: the out-of-time-
ordered correlator (OTOC) signals quantum-information scrambling in many-body systems …

Weak values are quantities accessed through quantum experiments involving weak
measurements and postselection. It has been shown that “anomalous” weak values (those …

In quantum mechanics, the concept of weak measurements allows for the description of a
quantum system both in terms of the initial preparation and the final state (post-selection) …

Weak values arise experimentally as conditioned averages of weak (noisy) observable
measurements that minimally disturb an initial quantum state, and also as dynamical …

It is argued that a weak value of an observable is a robust property of a single pre-and
postselected quantum system rather than a statistical property. During an infinitesimal time a …

One of the ambitious goals of artificial intelligence is to build a machine that outperforms
human intelligence, even if limited knowledge and data are provided. Reinforcement …

Macrorealism is a classical world view asserting that the properties of macro-objects exist
independently and irrespective of observation. One practical approach to test this view in …
