Scientists uncover a way to outsmart quantum entanglement loss with a single move

Scientists from the Raman Research Institute (RRI), an autonomous institution of the Department of Science and Technology (DST), alongside researchers from the University of Calgary and Louisiana State University, have discovered a method to preserve quantum entanglement and prevent 'entanglement sudden death' using a well-timed single flip operation. Partially funded by the National Quantum Mission, the study demonstrated that applying a population-swapping operation at a precise time during the decay process can delay, avoid, or hasten the loss of entanglement without altering hardware. The experimental setup also revealed a tuning parameter that connects two separate textbook noise models within a single framework.
