Quantum-squeezed laser light shows less noise in the statistics of the detected photons than shot noise, even though shot noise represents the lowest noise of all conventional lasers.
What the group calls a “squeeze laser” can establish correlations between detected photons. These so-called quantum correlations can be used to:
- improve ultra-sensitive measurements beyond what is possible with conventional ultra-stable laser light
- raise the security of quantum key distribution to a new level
- build optical quantum computers
Read how the group used a Koheras BOOSTIK for their experiments.
