Scientists discover Time Teleportation, Mr. Fusion still a ways off.
This doesn’t mean that we can all hop on over to “Star Wars” times just yet. But it does prove that we know little to nothing about how the laws of time and how matter interacts with them.
Previously, we knew that quantum teleportation works in space. Two identical particles at different locations are linked in such a way that, when you change the state of one, the other one instantly changes in exactly the same way, no matter how much the distance is between them. That discovery defied our understanding of reality, and it just got even more complex with this discovery.
University of Queensland’s scientists Jay Olson and Timothy Ralph claim that the quantum entanglement is a fundamental part of the universe, and it works both in space and time, so changing the state of particle today instantly changes the same particle in the future, even while the particle will not exist between those two points. This is how it works
imagine an experiment that Ralph and Olson describe in which a qubit is sent into the future. The idea is that a detector acts on a qubit and then generates a classical message describing how this particle can be detected. Then, at some point in the future, another detector at the same position in space, receives this message and carries out the required measurement, thereby reconstructing the qubit.
But there’s a twist. Olson and Ralph show that the detection of the qubit in the future must be symmetric in time with its creation in the past. “If the past detector was active at a quarter to 12:00, then the future detector must wait to become active at precisely a quarter past 12:00 in order to achieve entanglement,” they say. For that reason, they call this process “teleportation in time”.
I think this is pretty cool. Although right now it seems to be a lot of hoops to jump through just to pseudo travel through time. Now, I wish some scientist can prove this to me in plain English.
