Simply stated, retrocausality assumes that influences can travel backwards in time.

Simply stated, retrocausality assumes that influences can travel backwards in time. When an experimenter decides how to measure a particle, that choice can influence the properties of that particle — or, an entangled particle in the past. This, therefore, makes the “action at a distance” part of Einstein’s definition unnecessary. Instead, the entanglement effect becomes retrocausal influence. That being said, it’s not the same thing as sending signals back in time.

An interesting idea, but consider the implications for "free will".

Physicists May Have Discovered One of the Missing Pieces of Quantum Theory

'The quantum world is full of phenomena scientists are still largely grappling with on a theoretical level. One such quantum theory is quantum entanglement. Although there are a number of tests that demonstrate what Einstein called “spooky action at a distance,” — many merely assume that it happens, without being able to explain how. At least not yet. But two physicists have proposed an alternative that might just be able to explain this quantum effect.Essentially, quantum entanglement assumes that measurements of quantum properties within the state of one entangled particle occurs simultaneously with its entangled pair, regardless of how far apart they are. There isn’t any known mechanism that would explain that kind of influence, though, which is why physicists Matthew S. Leifer at Chapman University and Matthew F. Pusey at the Perimeter Institute for Theoretical Physics have offered an alternative: the team has asserted the idea of “retrocausality” as a possible explanation for this “spooky action.” Their findings were published in the journal Proceedings of The Royal Society A in June.
