• Chinese scientists say they have demonstrated a new way to produce entangled photons – a fundamental ingredient in quantum communication and computing – with unprecedented efficiency.
  The method has the potential to conserve laboratory resources and accelerate research into quantum relay, a key technology for long-distance, attack-proof quantum communication, according to researchers from the University of Science and Technology of China in the southeastern province of Anhui.
