What the study found
The study reports that mechanical noise squeezing was transferred between two mechanical modes using a single microwave cavity mode as the mediator.
Why the authors say this matters
The authors say that mechanical noise squeezing across multiple modes is important for precision measurements, and they describe the observed squeezing transfer as a viable option for enhancing precision measurements.
What the researchers tested
The researchers worked with two mechanical modes coupled to one microwave cavity mode. They generated squeezing in one mode, called the control mode, by parametrically modulating its resonance frequency through the optical spring effect, and then used an optomechanical beam-splitter interaction to transfer that squeezing to the target mode.
What worked and what didn't
Noise squeezing was achieved in the control mode and transferred to the target mode. Strong correlations between the quadratures of the two mechanical modes supported the conclusion that the target-mode squeezing came from the control mode. The abstract also says the observed transfer shows features of both single-mode and two-mode squeezing.
What to keep in mind
The abstract does not describe experimental limitations, boundary conditions, or failure cases beyond noting that the transfer had not yet been experimentally realized before this work.
Key points
