It is known that weak measurement can significantly amplify the mean of measurement
results, sometimes out of the range limited in usual quantum measurement. This fact, as …

Sensors that harness exclusively quantum phenomena (such as entanglement) can achieve
superior performance compared to those employing only classical principles. Recently, a …

Through the von Neumann interaction followed by post-selection, we can extract not only the
eigenvalue of an observable of the measured system but also the weak value. In this post …

We present a procedure to completely determine the complex modular values of arbitrary
observables of pre-and postselected ensembles, which works experimentally for all …

We investigate, within the weak measurement theory, the advantages of nonclassical pointer
states over semiclassical ones for coherent, squeezed vacuum, and Schrödinger cat states …

We explore the possibility of using “weak” measurements to carry out quantum state
tomography via numerical simulations. Given a fixed number of copies of identically …

Nonequilibrium dynamics is a paramount scenario for studying quantum systems. The
emergence of new features with no equilibrium counterpart, such as dynamical quantum …

The weak-value amplification is extensively considered in precision metrology in order to
achieve a higher sensitivity. Despite the practical benefits in amplifying small physical …

Decoherence of weak values is studied by means of an exactly solvable model of pure
dephasing. Expressions of weak values are derived for an irreversibly evolved qubit from a …

Solid-state magnetometers like the nitrogen-vacancy (NV) center in diamond have been of
paramount importance for the development of quantum sensing with nanoscale spatial …
