Measuring unrecorded measurement [PDF]

EPL (Europhysics Letters), 2016
Projective (Von Neumann) Measurement of an operator (i.e. a dynamical variable) selected from a prescribed set of operators is termed unrecorded measurement (URM) when both the selected operator and the measurement outcome are unknown, i.e. "lost". Within classical physics a URM is completely inconsequential: the state is unaffected by measurement ...

Non-thermal plasma disinfecting procedure is harmless to delicate items of everyday use

Scientific Reports, 2023
Non-thermal plasma (NTP) is a well-known decontamination tool applicable for a wide range of microorganisms and viruses. Since the recent COVID-19 pandemic highlighted the need to decontaminate all daily used items, it is highly desirable to address the ...

Configurable Pseudo Noise Radar Imaging System Enabling Synchronous MIMO Channel Extension

Sensors, 2023
In this article, we propose an evolved system design approach to ultra-wideband (UWB) radar based on pseudo-random noise (PRN) sequences, the key features of which are its user-adaptability to meet the demands provided by desired microwave imaging ...

Quadratic Quantum Measurements [PDF]

, 2004
We develop a theory of quadratic quantum measurements by a mesoscopic detector. It is shown that quadratic measurements should have non-trivial quantum information properties, providing, for instance, a simple way of entangling two non-interacting qubits.
