Re-interpretations for an experiment on the back-action in a weak measurement

Abstract (in Japanese) (See Japanese page) 
(in English) Interpretations of an experiment on the back-action in a weak measurement in [M. Iinuma et al., New J. Phys. {bf 13} (2011), 033041] are revisited. We show two different but essentially equivalent interpretations for this experiment along the original scenario of weak measurements proposed by Aharonov, Albert, and Vaidman. To do this, we introduce the notion of extended weak values which is associated not only with the states of the system but also the state of the measuring device. We also evaluate fluctuations in this experiment and found that an optimal measurement strength exists for a fixed polarization angle prepared as an initial state, at which fluctuations in measurement results vanish.
