I Why Are There So Few Quantum Time Machine Models?

[avpol]

As of today, there are plenty of time machine mathematical models based on general relativity theory (warp drives, wormholes), but few ones based on quantum physics. However, back in 2010, Seth Lloyd wrote: "quantum mechanics supports a variety of counter-intuitive phenomena which might allow time travel even in the absence of a closed timelike curve in the geometry of spacetime."
So, why are there so few quantum physics based time machine models if they may be promising?
Thanks.

Perhaps most quantum physicists have better things to spend time on?

But once they invent a time machine, they'll have all the time they want.

Promising for what? Actual time travel? The technical term for that concept is "horse manure"

Can you point to some of those few models.

Yeah I got sucked in. Here you go (from 2010):

For the OP: their answer seems to be that absent Closed Timelike Curves somehow tunneling will will get you there. That's not a lot to go on...which answers your question I believe/

scientists avoid publishing research on this topic due to fear of the Time Police

due to fear of the Time Police

Not to worry, they are way too busy chasing Time Bandits to bother with the scientists...

Thanks! He wrote about "a number of ways." Tunneling is just one of them:-).

Quantum physics based models? Seth's one, for example.

Say it to Mr. Thorne, recent Nobel Laureate;-). That his opinions are horse manure.

If you think that Kip Thorne believes anyone is going to build an actual time machine based on the wormhole metrics he has published, you are seriously mistaken.

(Also, his Nobel Prize was for LIGO, not for time travel.)
