Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.
If gamblers, investors and quantum experimentalists could bend the arrow of time, their advantage would be significantly higher, leading to significantly better outcomes.
"Now imagine you can change what you send on day one with the information from the wish list received on day two. Our simulation uses quantum entanglement manipulation to show how you could retroactively change your previous actions to ensure the final outcome is the one you want." "The effect is remarkable, but it happens only one time out of four!" said Arvidsson-Shukur."In other words, the simulation has a 75% chance of failure. But the good news is that you know if you have failed. If we stay with our gift analogy, one out of four times, the gift will be the desired one , another time it will be a pair of trousers but in the wrong size, or the wrong colour, or it will be a jacket.
"Consider our earlier analogy about gifts," said co-author Aidan McConnell, who carried out this research during his master's degree at the Cavendish Laboratory in Cambridge, and is now a PhD student at ETH, Zürich."Let's say sending gifts is inexpensive and we can send numerous parcels on day one. On day two we know which gift we should have sent.
