Building on this Landau-Wigner conjecture, it became possible to demonstrate that time reversal is exponentially improbable in a virgin nature and to design an algorithm artificially reversing a time arrow for a given quantum state on the IBM quantum computer. However, the implemented arrow-of-time...
A quantum computer able to effectively jump back and clean up errors as it works could operate far more efficiently. To achieve the time reversal, the research team developed an algorithm for IBM's public quantum computer that simulates the scattering of a particle. Inclassical physics, this mi...
This is implemented experimentally by modeling a real system, the electron scattered on the two-level systems, on the IBM quantum computer. In this respect we utilize the conjectures by Lloyd6. Further, a principal possibility of occurring of the time reversal was discussed in20. Reversal of ...
LONDON, March 14 (Xinhua) -- Scientists have successfully returned the state of a quantum computer a fraction of a second earlier, moving a significant step closer to proving the reversal of "the arrow of time," according to a new study published Wednesday in Scientific Reports. "We have ar...
(there is an excellent videoherefrom Scientific American) they offer an exponential increase in processing capacity. A quantum computer can consider all possible outcomes to a problem at the same time, rather than sequentially as classical computers do. The result, a computer that could potentially...

A number of examples is provided in the directorytest. The expected output files are included with the code. This can serve as a "known answer" test of the code. The expected run time on a normal desktop computer for all the tests is of the order of an hour. ...
These experiments compress the model based on its symmetries; methods of this form, while having running time scaling polynomially with system size, are complex enough that solving a post-classical Fermi-Hubbard instance would not be viable on a near-term quantum computer. Here we instead use an...
