Raman Research Institute Shows a Precisely-Timed 'Flip' Can Control Quantum Entanglement Loss

Physicists at Bengaluru's Raman Research Institute, working with the University of Calgary and Louisiana State University, have shown that a single precisely-timed polarization flip can prevent, delay, or hasten the abrupt loss of quantum entanglement known as entanglement sudden death, turning timing itself into a tool for protecting fragile quantum links.
