Raman quantum memory demonstrates near-unity performance
Over the past decades, quantum physicists and engineers have developed numerous technologies that harness the principles of quantum mechanics to push the boundaries of classical information science. Among these advances, quantum memories stand out as promising devices for storing and retrieving quantum information encoded in light or other physical carriers.Quantum Physics NewsRead More
Reading a quantum clock costs more energy than running it, study finds
A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. In a study published in Physical Review Letters, scientists demonstrate that the energy cost of “reading” a quantum clock far outweighs the cost of running it, with implications for the design of future
