What is the basic Idea of entangled Weak Measurements? Finally Understanding the Double Slit Experiment: Yakir Aharonov

 Yakir Aharonov (who is next to impossible to understand due to his thick accent and voice qualities). haha. 28 minutes

An atom, with its finite rest mass, can be brought to rest and can thus have a simultaneous position and momentum, even though we will not be able to measure these values simultaneously using a von Neumann-type strong measurement.
However as we have seen above in section 6.3.3, this simultaneous momentum is the Bohm momentum, which is not an eigenvalue of the momentum operator in the state under consideration, but the weak value defined in equation (6.13).
This means that this momentum can be measured by making the appropriate weak measurement of the momentum operator.
