First noiseless single photon amplifier

Academics / General Science : Science Daily (2 years ago)

Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The next step will be to build additional quantum teleportation into the experiment, wh... Read Post
