"...It all falls apart in the first sentence:<br /> <br />"Using an IBM quantum computer, they managed to undo the aging of a single, simulated elementary particle by one millionth of a second." <br /> <br /> What a complete and utter waste of electricity. A single "simulated elementary particle"... does not exist in actual time in any way, IT ISN'T REAL, ergo, it can't age or de-age except as a fiction. Here's another profound revelation: pressing the play followed by the rewind button on a VCR doesn't make 'simulated' time go backwards either.

All of the quantum algorithms depend on qubits, and on electronic gates that do time reversible operations on qubits.''<br /><br />No, they don't. What they instead count on is: the linearity of QM. Never forget this part. Grant them the ``inherent'' etc. linearity of QM, and they go wild---because you granted them it. They never did concern themselves with the qubits in the first place (i.e., way back in the 1950s and earlier, in the late 1920s).<br /><br />I am writing this rather directly, and I will let you know, after a drink and before a dinner. But I also do think that I am right on money on this one.<br /><br />Let them live in their ``linear'' world, erected for them by their own mathematicians. Just know that the real world isn't that.<br /><br />More, later. (And sorry for keeping you waiting, but in all fairness, I guess I made my point when I wrote that Outline document and posted it at iMechanica and all... )<br /><br />But yes, a more detailed response is necessary, and I shall post it once I land a job in Indian IT industry. A very well-paying one, in fact.<br /><br />Bye for now.<br /><br />Best,<br /><br />--Ajit<br /><br /><br />Ajit R. Jadhavhttps://ajitjadhav.wordpress.comnoreply@blogger.com
