Abstract:Recently, weak value A w derived in the pre-and post-selected weak measurement has been shown to be powerful in measuring minute physical effects. In principle, the decrease in the post-selection probability will increase the sensitivity. Besides, the sensitivity which characterizes the pointer position shift is proportional to the real part of A w , and the sensitivity which characterizes the pointer shift in momentum space is proportional to the imaginary part of A w . However, we find that the relationship … Show more
