Vibration isolation is an engineering technique that mechanically decouples sensitive equipment from ambient structural or acoustic vibration, using damped mounts, pneumatic isolators or active feedback systems to attenuate disturbance across a target frequency band. It is essential wherever nanometre- or sub-wavelength-scale positional stability is required, since even small vibrations can blur measurements or misalign optical paths. Precision manufacturing tooling and quantum network nodes both depend on vibration isolation to hold tolerances that ambient building or seismic vibration would otherwise violate.
