Quantum computer reverse time is the process of using a quantum computer to reverse the flow of time. This could be used to undo mistakes, or to travel back in time to before a disaster occurred.

Quantum computers are special kinds of computers that use quantum bits, or qubits. These computers can do some amazing things that regular computers can’t, including solving problems faster than any classical computer.

Now, some researchers at the University of Bonn in Germany have shown that quantum computers can also reverse time. They did this by reversing the state of a qubit that had been …
