Weak measurement of cotunneling time
Quantum mechanics allows the existence of “virtual states” that have no classical analog. Such virtual states defy direct observation through strong measurement, which would destroy the volatile virtual state. Here, we show how a virtual state of an interacting many-body system can be detected employing a weak measurement protocol with post-selection. We employ this protocol for the measurement...

متن کاملWeak Force Measurement in Bistable Optomechanical System
One of the main milestones in the study of opto-mechanical system is to increase the sensitivity of weak forces measurement up to the standard quantum limit. We have studied the detection of weak force under a bistable condition in red detuned regime. In this case, dynamics of the system behaves asymptotically similar to stationary state and applying external force affects phase and fluctuation...
متن کاملRelativistic Time of Arrival
We propose a covariant algorithm for relativistic ideal measurements and for relativistic continuous measurements, its non-relativistic limit results the algorithm of the Event-Enhanced Quantum Theory. Therefore an additional intrinsic parameter, the proper time, is used. As an application we compute the time of arrival of a particle at a detector and find good agreement between the expected va...
متن کامل(Time-Of-Arrival), AOA (Angle-Of-Arrival), and TDOA
The localization of robots is a main problem to solve to make the robots navigate autonomously. This paper introduces an embedded indoor localization system for mobile robot. The system consists of a localization sensor that computes location of itself and infrared landmarks that are wirelessly controlled by the localization sensor. The localization sensor which is combined with an image sensor...
