Physicists from DGIST and collaborators have identified the microscopic process behind ultrafast electronic decoherence in solids, finding that quantum states collapse within 1–2 femtoseconds due to ...
Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...
"Our nonlinear system transmits quantum information with 94% fidelity, compared to the theoretical limit of 33% on systems using linear optical components," said Kejie Fang, an Illinois professor of ...
