Rapid progress in the development of metamaterials and metaphotonics allowed bulky
optical assemblies to be replaced with thin nanostructured films, often called metasurfaces …

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 …

In standard quantum weak measurements, preselection and postselection of quantum states
are implemented in the same photon. Here we go beyond this restrictive setting and …

In this work, we theoretically propose an optical biosensor (consists of a BK7 glass, a metal
film, and a graphene sheet) based on photonic spin Hall effect (SHE). We establish a …

We use numerical simulations to demonstrate third-harmonic generation with near-unity
nonlinear circular dichroism (CD) and high conversion efficiency (10− 2 W− 2) in asymmetric …

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

We present a weak measurement protocol that permits a sensitive estimation of angular
rotations based on the concept of weak-value amplification. The shift in the state of a pointer …

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 …

One drawback of conventional quantum state tomography is that it does not readily provide
access to single density matrix elements since it requires a global reconstruction. Here, we …
