Physicists reverse time using quantum computer
Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study is published in Scientific Reports .
Reversing time on demand
The researchers then attempted to reverse time in a four-stage experiment. Instead of an electron, they observed the state of a quantum computer made of two and later three basic elements called superconducting qubits.
The researchers found that in 85 percent of the cases, the two-qubit quantum computer returned back into the initial state. When three qubits were involved, more errors happened, resulting in a roughly 50 percent success rate. According to the authors, these errors are due to imperfections in the actual quantum computer. As more sophisticated devices are designed, the error rate is expected to drop.
Interestingly, the time reversal algorithm itself could prove useful for making quantum computers more precise. "Our algorithm could be updated and used to test programs written for quantum computers and eliminate noise and errors," Lebedev explained.

Did, I get that right, Larry Hampton, I may be in two places at once if you stare at me?
Very cool article Larry....Back to the Future.
Thanks kavika. Jay Leno bought one of these time travel machines sometime ago...
;~)
We were at a classic car show this past weekend and there was a perfect DeLoren there. Very cool
I believe that qualifies as an oxymoron, lol.
I always heard that one could travel through space and time is different.
As one can travel for five years yet 50 years may have past on Earth.
You musta been reading Isaac Asimov - he was the genius of SF.
Would have liked seeing a video of the activity - but the one on the Sun was very jerky and not focused.
That sounds like time dilation. The closer you get to a strong gravity well, like a black hole, the more time "slows" down from the viewer's perspective, if I have that correct.
Do you think they can use this stuff as a way to make us age in reverse i.e. get younger?
Problem is we are tissue, bone, muscle, mind, and . . . . Everything an organic creature is - is a product of time moving in one direction: forward. It would seem (to me anyway) that in order to reverse flesh aging, it needs to occur individually, organically, and not as a uniform setting.
I can be wrong in my thinking, however.
True CB. There are only a few species capable of rejuvenating.
And even rejuvenation is forward-action, yes?
Well, I wouldn't mind rejuvenating.
HA!
I'm signing up.
Truthfully, I did Travel Through Space & Time on a peyote trip in the early 1970s and fell through the Center of the Universe. I flipped head over heel, at a delightful speed. Stopped!
Heard GOD's voice!
He said, "I can only do GOOD". (Meaning, he, God, can only do good.)
Instantly, I reversed, "head over heels" and entered our dimension through a metal wall.
Few, to this day, except for American Indians, value this experience. Nearly everyone I tell it to thinks I am nuts. Even, at times, me.
From that experience, I understand better the concept of multiple dimensions.
What seemed like a long time, happened, it seemed to me that "Time stood still".
At the time, I misinterpreted the experience, rushing to tell my friend in the other room that, "God has limitations".
The only one that had limitations was me.
It is a bit off-topic, which is why I hesitated to post until now:
I won't leave you hanging, nevertheless. . . . Many years back, I had quite a few (really good) experiences with such psychoactive products. I did not see or hear God but I saw "a great many profound things" which I keep in my heart to this day! (Oh, and Pink Floyd's, The Wall, was my anthem.)
Once I experienced going so deep into my own 'self' that I saw myself as an old man - startled, I left that level rapidly!
....I have noticed over the years that various drugs (as well as other things proporting to provide these sorts of unique "spiritual" experiences, change. Different things go in and out of style-- what's "hip"-- what's "cool". (ex: Ayahusca.) .
And what is considered not cool.
P.S. over the years I've tried many recreational drugs. Interestingly, the first one I used was Peyote (in the early 1960s)-- in fact I did Peyote well over a year before I even tried Marijuana!
Well, some of them might be right! (Others ...not so much!!! )
I always suspected that Peyote or LSD or some other hallucinogenic were involved somewhere in your thought processes.
Time and Space are an illusion. (And, at the same time...they are not).
(And that's all I wish to say on the topic at this time )
This is absolutely fantastic.
I miss so much stuff here and this is just one example, but this is fantastic news. This is a story that deserves the oft wrongly applied "WOW, Just WOW".
Really.
Indeed. Could we be seeing the beginning of time travel technology?
Maybe?...and in reverse of all things!
Go back in time, change a few things. Then we have an alternate, more dystopian timeline to deal with.
Knowing you, that first 'bible' would be knocked from the hands of its recipient! HA!
Reminds me of a Ray Bradbury short story.
Which one?
Oh c'mon! You know I got in your 'wellspring' with that one!
I want to offer something to ponder:
In the universe 'of things': Things apparently have its opposites. Therefore, every disease has a cure. Time moves forward-it can move backwards.
No matter one's view of the universe, that it is God driven or random, we can respect that we are learning of its potential completeness of 'transactions.' I suggest that the universe is a full container of all possibilities it offers—nothing left open-ended.
The hard part. It appears to be man's responsibility to figure it all out.
One more thing about time moving forward and backwards then. There can not possibly exist any "us" before tomorrow.
Yeah, no!
You really don't like me, do ya! (CB pouts.)
I have no idea what you're talking about or what your point is.
Okay. Got it.
Forgot the title. Was what I call the original Butterfly Effect.
It happened in a time when we could look back in time for big game hunters to travel back to when a dinosaur was about to die, and the hunter could show up to make the kill.
Supposedly, the currents of time would be left unchanged.
One time, a fella stepped on a butterfly during his trip to take his big game. He returned home to a dystopian society.
Wasn't that the plot line of one of the Simpsons Halloween episodes?
Could have been. I don't know. I imagine it would be a funny one with Homer going back in time to mess something up.
Found it. It's in 2 parts. Part 1 . Part 2
THAT is hilarious!
Thank you Gordy.
My pleasure.
"Time reversal. A special program modifies the state of the quantum computer in such a way that it would then evolve "backwards," from chaos toward order."
Any chance it might work in US politics? We could seriously use a 2016 reset where we could go back from this nightmare chaos to actual functional order.
Drop me off at Dec. 26th, 1987....so I can push my (now x) wife to be in front of a bus instead of marrying that life sucking bitch.
Wow, thats cold. Even for you Frosty, LOL
Wouldn't be easier to make that last minute decision not show up for the wedding?
Heck, I did it.
