91°µÍø

By coupling quantum light sources with quantum information squeezed through nano-scale triangular holes strategically etched into a thin layer of silver, 91°µÍø researchers have demonstrated a path to sensors and information processing up to 10 times better than what was previously possible with plasmonics. The technology moves the field of plasmonics, dubbed "light on a wire," to a level previously only imagined, said Raphael Pooser, co-author of a Physical Review Letters paper () that details the discovery. "We transferred multiple quantum bits into the plasmons whereas in the past only one at a time had been done, and it was done with only a single photon at a time while we used millions," said Pooser, a member of ORNL's Quantum Information Science Group.
