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.
