Quantum limits on detection sensitivity of a linear detector with feedback [PDF]
, 2016 We show that the detection sensitivity of a linear detector is lower bounded by some quantum limits. For the force detection, relevant for atomic force microscopes, the lower bound is given by the so-called ultimate quantum limit. For the displacement detection, relevant for detecting gravitational waves, a generalized lower bound is obtained.

Optical spin-wave detection beyond the diffraction limit [PDF]
, 2022 Spin waves are proposed as information carriers for next-generation computing devices because of their low power consumption. Moreover, their wave-like nature allows for novel computing paradigms. Conventional methods to detect spin waves are based either on electrical induction, limiting the downscaling and efficiency complicating eventual ...

Detection of amplitude modulation with squeezed light for sensitivity beyond the shot-noise limit [PDF]
, 1988 An improvement in precision beyond the limit set by the vacuum-state or zero-point fluctuations of the electromagnetic field is reported for the detection of amplitude modulation encoded on a weak signal beam. The improvement is achieved by employing the

Charge Detection in a Closed-Loop Aharonov-Bohm Interferometer [PDF]
, 2006 We report on a study of complementarity in a two-terminal "closed-loop" Aharonov-Bohm interferometer. In this interferometer, the simple picture of two-path interference cannot be applied.

Detection-Response Task—Uses and Limitations [PDF]
Sensors, 2018 The Detection-Response Task is a method for assessing the attentional effects of cognitive load in a driving environment. Drivers are presented with a sensory stimulus every 3–5 s, and are asked to respond to it by pressing a button attached to their finger.
