The Quantum Butterfly Effect And Simulating Quantum 'Time Travel'

In research by a team at Los Alamos National Laboratory, Alice prepares her qubit and applies the information scrambling unitary U to this and many other qubits altogether. Bob measures her qubit in any basis, flipping the qubit to the state not known to Alice. Alice still can reconstruct her information via a single decoding unitary U†.

The Quantum Butterfly Effect And Simulating Quantum ‘Time Travel’

Eddie Gonzales Jr. – MessageToEagle.com – Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no “butterfly effect.” In the research, information—qubits, or quantum bits—’time travel’ into the simulated past. One of them is then strongly damaged, like stepping on a butterfly, metaphorically speaking. In research by … Continue reading The Quantum Butterfly Effect And Simulating Quantum ‘Time Travel’
