At a NATO workshop on predetection of terrorism, we asked: Is it possible to build a forward time camera (FTC), to take pictures of the future? (My chapter: www.werbos.com/NATO_terrorism.pdf.)
The quick answer: if the cosmos actually obeys the dynamic laws assumed by mainstream physics, there is no reason why not -- BUT if all of our measurement systems exactly follow the ad hoc rules (like "the Born rule") which physicists have assumed in the past, then it would be impossible.
Are those measurement rules valid, or should we replace them by time-symmetric rules which tell us that we CAN build a time forward camera? (Actually a prototype is actually under construction right now...)
Today I posted a highly mathematical (and citeable) paper on what the "Born rule" actually predicts for some tricky experiments which have not yet been done, which I believe should prove that today's Born rule is wrong:

One guy said "So what? We already know that the Born rule works. Why should we test it in new circumstances?"
But folks studying gravity don't think that way. They are happy to test general relativity (GR) in a wide range of new situations, to prove more and more that it does work, and to find out just in case there is reason to try to upgrade it. Why don't quantum folks think the same way?
It reminds me of an NSF review panel which I once observed (not my panel). When the proposal for a new experiment came up, the first reviewer said "This is very interesting. We should fund it." But then a very proud second reviewer said "No way. It is too high risk." First reviewer: "What is the risk?" Second reviewer: "It might demonstrate that MY theory is false." I often wonder how many scientists really remember how the scientific method is supposed to work. But of course, no one is surprised when some "Christians" seem to advocate stoning women...
Still, in this case, the only labs which produce triple entanglement now are in China, except for one in Austria where Pan Jianwei is close to his former professor who supported him when he figured out how to do it.
