Time averaging of weak values—consequences for time-energy and coordinate-momentum uncertainty

open access: yesNew Journal of Physics, 2018
Using the quantum transition path time probability distribution we show that time averaging of weak values leads to unexpected results. We prove a weak value time energy uncertainty principle and time energy commutation relation. We also find that time averaging allows one to predict in advance the momentum of a particle at a post selected point in ...
