Coherence phenomena arise from interference, or the addition, of wave-like amplitudes with
fixed phase differences. Although coherence has been shown to yield transformative ways …

Since its introduction 25 years ago, the quantum weak value has gradually transitioned from
a theoretical curiosity to a practical laboratory tool. While its utility is apparent in the recent …

Metasurfaces based on resonant nanophotonic structures have enabled innovative types of
flat-optics devices that often outperform the capabilities of bulk components, yet these …

Operator noncommutation, a hallmark of quantum theory, limits measurement precision,
according to uncertainty principles. Wielded correctly, though, noncommutation can boost …

In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

Kirkwood-Dirac (KD) quasiprobability is a quantum analog of phase space probability of
classical statistical mechanics, allowing negative or/and nonreal values. It gives an …

Tabletop tests of quantum gravity (QG) have long been thought to be practically impossible.
However, remarkably, because of rapid progress in quantum information science (QIS), such …

Abstract The Kirkwood-Dirac quasiprobability distribution, intimately connected with the
quantum correlation function of two observables measured at distinct times, is becoming …

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 measurement of a quantum state poses a unique challenge for experimentalists.
Recently, the technique of 'direct measurement'was proposed for characterizing a quantum …
