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 …

Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

How to measure the optical conductivity of atomically thin crystals is an important but
challenging issue due to the weak light-matter interaction at the atomic scale. The photonic …

The technical merits of weak-value-amplification techniques are analyzed. We consider
models of several different types of technical noise in an optical context and show that weak …

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 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 …

Weak values and measurements have been proposed as a means to achieve dramatic
enhancements in metrology based on the greatly increased range of possible measurement …

Weak-value amplification (WVA) is a metrological protocol that amplifies ultrasmall physical
effects. However, the amplified outcomes necessarily occur with highly suppressed …

Weak measurements have been under intensive investigation in both experiment and
theory. Numerous experiments have indicated that the amplified meter shift is produced by …
