And no, based from the video we do not know if ER=EPR yet. Not until the paper(s) get peer reviewed, and other researchers repeat the experiment. |

--- Quote from: vad on December 04, 2022, 01:33:25 am ---Google’s quantum computer is an expensive toy with just only 53 qubits. It cannot outperform classical computer, other that in a handful computational tasks specifically crafted to demonstrate quantum supremacy that do not have any meaningful application. You cannot use it even for factorization of 32-bit integers (the largest arbitrary number factored by a quantum computer is 17 bits long), let alone computationally solve equations for some advanced simulations. If the researchers needed to run some simulations, they would have done that on a classical computer, IMO. --- End quote --- I don't believe they are doing any numerical computation / simulation. I think they are utilizing the computer's ability to entangle 2 or more quantum bits and injecting a disturbance to see what happens when reading the entangled pair. Their resulting readback disturbance is an analog to what would be seen as a negative energy presence if they had computed / simulated the results using classical computers. IE: They setup a few physical entangled q-bit pairs to see if it reacts the same way to one of classically computed entangled particles theory which uses negative energy worm holes connecting the 2 entangled particles, and they got a match between the theoretical theory which required negative energy and how the physical entangled Q-bits in the quantum computer behaved. It's not that they were trying to make the computer compute the entangled particle theory which requires negative energy, it's that they had the entangled bits in the Quantum computer, applied some stimuli, read the results to see if it matched the theory. The 7 q-bits they used is not enough to do and verify any such classical physics computation. They use the quantum computer to measure itself to verify is it matched the theory which used some negative energy to connect the entangled bits and the results match the theory. |

It is a good idea, assuming if the math is truly identical. However, since there is little yet to suggest the underlying Physics are identical, it is in my opinion a significant assumption here to assume similarity is beyond skin deep. |

It does not matter if you use analog computer, digital computer, quantum computer, abacus or pen and paper. You need experiment for that. |

They have a box which has entangles bits with wiring to stimulate and read those entangled bits. They throw in controlled random junk and readback the results. They now check to see which theories about entangled particles currently exist match what they see. It turns out that one of those theories which predicts a type of signal if negative energy exists and that signature was found in the read results. It is not that they wrote some quantum program to detect if negative negative energy exists or can be created. It is that they wanted to do a precise experiment with entangled particles to see if it exists. It would have been cost prohibited to make such a precise experiment on their own. However, some Quantum computers already had all the necessary (and then some) hardware elements to perform their experiment. The looked at the noise and errors of the quantum computer hardware and saw a signature in that noise which coincides with negative energy in some existing physics theories. |
