Can apparent superluminal neutrino speeds be explained
as a quantum weak measurement?
If recent measurements [1] suggesting that neutrinos travel faster than light
survive scrutiny, the question of their theoretical interpretation will arise. Here
we discuss the possibility that the apparent superluminality is a quantum
interference effect, that can be interpreted as a weak measurement [2, 3].
Although the available numbers suggest that this explanation is not correct, we
consider the idea worth exploring and reporting – also because it might suggest
interesting experiments, for example on electron neutrinos, about which
relatively little is known. A similar suggestion, though not interpreted as a weak
measurement and not accompanied by numerical estimates, has been proposed
independently [4].
