Reduced Decoherence of Macroscopic States Using Squeezing and Anti-Squeezing
R. A. Brewster, J. D. Franson · Frontiers in Optics / Laser Science · 2018
The decoherence of macroscopic quantum states due to loss can be reduced by squeezing before transmission, followed by amplification and anti-squeezing to restore the original amplitude. This approach does not decrease the data transmission rate.
