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

Fast gating in Raman spectroscopy is used to reject the fluorescence contribution from the
sample and/or the substrate. Several techniques have been set up in the last few decades …

The weak value concept has enabled fundamental studies of quantum measurement and,
recently, found potential applications in quantum and classical metrology. However, most …

Quantum measurement remains a puzzle through its stormy history from the birth of quantum
mechanics to state-of-the-art quantum technologies. Two complementary measurement …

Bell inequalities represent one of the cornerstones of quantum foundations, and a
fundamental tool for quantum technologies. Although a lot of effort was put in exploring and …

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 …

Quantum nonlocality offers a secure way to produce random numbers: Their unpredictability
is intrinsic and can be certified just by observing the statistic of the measurement outcomes …

When an observable is measured on an evolving coherent quantum system twice, the first
measurement generally alters the statistics of the second one, which is known as …

Leggett-Garg (LG) tests for macrorealism were originally designed to explore quantum
coherence on the macroscopic scale. Interference experiments and systems modeled by …

Sequential weak measurements of non-commuting observables are not only fundamentally
interesting in terms of quantum measurement but also show potential in various …
