Qubit POVMs by destructive weak measurements
Yi-Hsiang Chen, Todd A. Brun
Many quantum measurements, such as photodetection, can be destructive. In photodetection, when the detector clicks a photon has been absorbed and destroyed. Yet the lack of a click…

Decomposing qubit positive-operator valued measurements into continuous destructive weak measurements
Yi-Hsiang Chen, Todd A. Brun
It has been shown that any generalized measurement can be decomposed into a sequence of weak measurements corresponding to a stochastic process. However, the weak measurements may…
