As if Quantum Teleportation Weren't Spooky Enough, Physicists Propose 'Time Teleportation'

As if the idea ideas of quantum entanglement and time travel weren’t difficult enough to wrap one’s head around separately, two physicists at the Universtiy of Queensland in Australia have further compounded the headache by merging the two ideas via a new kind of quantum entanglement that links particles not across space, but across time.

Quantum entanglement is that “spooky action” (Einstein’s words, not ours) that links two particles such that a measurement on one immediately influences the state of the other, even if the two particles are separated by miles, or even light years. Entanglement defies the intuitive way we understand the universe to work (as does most of quantum mechanics). The idea of “time teleportation,” as described by S. Jay Olson and Timothy Ralph, doesn’t add clarity but it does introduce some interesting questions about the fundamentals of the universe.

In a sense, everyone and everything is time traveling, moving forward in time at a given rate. What Olson and Ralph propose is that it’s possible to take a shortcut into the future without being present in the interim. How? Tech Review’s KFC explains:

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.

Great Scott!!

Great! I can go back intime and witness the birth of Christ... the signing of the Declaration of Independence, or to see if an ex GF Dina was sleeping with that scum ex-con she claimed was ‘just a friend’.

oops! 1961

Not exactly true.

Or go back and extend Stanley Ann's visit to Cuba for several more months.

"KFC explains"

Wow their chicken really is something! ;-)

Bells theorem proves non-locality.

But it is not just non-locality in terms of space, it is non-locality in terms of time also.

Before you get your hopes up...

If you decide to try to teleport to 1492, your head might get there.
But what if your liver decides to go to 1649??

You can’t say spooky any more. It’s racist. Denigrate is too.

[therightliveswithus]

This is both awesome and disturbing at the same time

Future? Feh.

So I still can't get home.

I'll not yet revise the lyrics to "Forever and All The Way Back".

Lol!

Quantum bump for later.......

[SengirV]

Been there, done that.

I think this was sort of the concept behind the time travel in the movie "Primer."

An excellent movie, btw.

Communications would be vastly improved if you could make this work. I'm sure AT&T or Verizon is working on it................Can you here me now?............

Is this ping list worthy?
