He refers back to J.P. Vignier - the personal assistant of de Broglie! This inspired me to review my overview research of de Broglie, so I learned more. There is this amazing pdf book linked - on Vignier and de Broglie
Just last year, physicist John Howell and his team from the University of Rochester reported success. In the Rochester setup, laser light was measured and then shunted through a beam splitter. Part of the beam passed right through the mechanism, and part bounced off a mirror that moved ever so slightly, due to a motor to which it was attached. The team used weak measurements to detect the deflection of the reflected laser light and thus to determine how much the motorized mirror had moved.http://discovermagazine.com/2010/apr/01-back-from-the-future
That is the straightforward part. Searching for backward causality required looking at the impact of the final measurement and adding the time twist. In the Rochester experiment, after the laser beams left the mirrors, they passed through one of two gates, where they could be measured again—or not. If the experimenters chose not to carry out that final measurement, then the deflected angles measured in the intermediate phase were boringly tiny. But if they performed the final, postselection step, the results were dramatically different. When the physicists chose to record the laser light emerging from one of the gates, then the light traversing that route, alone, ended up with deflection angles amplified by a factor of more than 100 in the intermediate measurement step. Somehow the later decision appeared to affect the outcome of the weak, intermediate measurements, even though they were made at an earlier time.
This amazing result confirmed a similar finding reported a year earlier by physicists Onur Hosten and Paul Kwiat at the University of Illinois at Urbana-Champaign. They had achieved an even larger laser amplification, by a factor of 10,000, when using weak measurements to detect a shift in a beam of polarized light moving between air and glass.
For Aharonov, who has been pushing the idea of backward causality for four decades, the experimental vindication might seem like a time to pop champagne corks, but that is not his style. “I wasn’t surprised; it was what I expected,” he says.
The Rochester experiments seem to demonstrate that actions carried out in the future—in the final, postselection step—ripple back in time to influence and amplify the results measured in the earlier, intermediate step.
Why must the quantum world always retain a degree of fuzziness when we try to look at it through the time slice of the present? That loophole is needed so that the future can exert an overall pull on the present, without ever being caught in the act of doing it in any particular instance.Wow not even 500 views - PRofessor Aharonov!

Aharonov is widely known for many monumental fundamental discoveries. For example, the presidential citation accompanying Aharonov's National Medal of Science recognizes him for "his work in quantum physics which ranges from the Aharonov-Bohm effect to the notion of weak measurement, making him one of the most influential figures in modern physics." The Aharonov-Bohm effect -- one of the cornerstones of modern physics -- was co-authored with David Bohm, whom Einstein regarded as his "intellectual son."
