Squeezed Light Reached Sixty Hertz on a Chip
A coherent reference comb stabilized two-mode squeezing without directly locking the fragile quantum modes.
Summary
A coherent reference comb stabilized two-mode squeezing without directly locking the fragile quantum modes.
A silica microcavity produced audio-band two-mode squeezed states down to 60 hertz. An orthogonally polarized reference comb enabled long-timescale phase control and covariance reconstruction; the reported symplectic eigenvalue of 0.395 confirmed inseparability.
Why it matters
A coherent reference comb stabilized two-mode squeezing without directly locking the fragile quantum modes.
Limits and context
No additional limitation was separately recorded.
