Geometric phase is a key player in many areas of quantum science and technology. In this
review article, several foundational aspects of quantum geometric phases and their relations …

Abstract Weak values and Kirkwood–Dirac (KD) quasiprobability distributions have been
independently associated with both foundational issues in quantum theory and advantages …

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

Weak value amplification (WVA) is a technique by which one can magnify the apparent
strength of a measurement signal. Some have claimed that WVA can outperform more …

The quantum statistical fluctuations of electromagnetic fields establish a limit, known as the
shot-noise limit, on the sensitivity of optical measurements performed with classical …

Based on high quality surgery and scientific data, scientists and surgeons are committed to
protecting patients as well as healthcare staff and hereby provide this Guidance to address …

We study quantum frequency estimation for N qubits subjected to independent Markovian
noise, via strategies based on time-continuous monitoring of the environment. Both physical …

In optical metrological protocols to measure physical quantities, it is, in principle, always
beneficial to increase photon number n to improve measurement precision. However …

Weak amplification and other postselection-based metrological protocols can enhance
precision while estimating small parameters, outperforming postselection-free protocols. In …

Weak-value amplification (WVA) is a metrological protocol that effectively amplifies ultra-
small physical effects, making it highly applicable in the fields of quantum sensing and …
