"Revolutionary Protocol Successfully Inverts Qubit Evolution"
Originally Published 2 years ago — by Phys.org
Researchers at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna have developed a universal mechanism to invert the evolution of a qubit with a high probability of success. The protocol can propagate any target qubit back to the state it was in at a specific time in the past, and can be applied to any qubit, irrespective of its natural time evolution or what state it is when the protocol is used. The researchers found that their universal quantum rewinding mechanism has a high probability of success, namely of 1.
