Calibration of Quantum Sensors by Neural Networks [PDF]

Physical Review Letters, 2019
Introducing quantum sensors as solution to real-world problem demands reliability and controllability outside laboratory conditions. Producers and operators ought to be assumed to have limited resources ready available for calibration, and yet, they should be able to trust the devices.

Robust approaches to remote calibration of a transmitting array [PDF]

, 2010
We consider the problem of estimating the gains and phases of the RF channels of a M-element transmitting array, based on a calibration procedure where M orthogonal signals are sent through M orthogonal beams and received on a single antenna.

SensorID: Sensor Calibration Fingerprinting for Smartphones [PDF]

2019 IEEE Symposium on Security and Privacy (SP), 2019
Sensors are an essential component of many computer systems today. Mobile devices are a good example, containing a vast array of sensors from accelerometers and GPS units, to cameras and microphones. Data from these sensors are accessible to application programmers who can use this data to build context-aware applications. Good sensor accuracy is often
