I Arrow of time and its reversal on a IBM quantum computer

I would like to know what the implications of this paper are https://arxiv.org/abs/1712.10057.

They say " Here we show that, while in nature the complex conjugation needed for time reversal is exponentially improbable, one can design a quantum algorithm that includes complex conjugation and thus reverses a given quantum state."

Is this true time reversal does the arrow of time reverse at least in the simulation?

Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

I often reverse the arrow of time using the rewind button on my TV remote control!

Such godlike powers were not meant for mere mortals.
 
Ok thanks I see it was not as profound as claimed.
Just for the record I I have a simulation of a perpetual pendulum running on my computer. Seems the paper is in this class of achievement albeit on a quantum computer.

Thanks again Andrew
