- Abstract: Squeezed light finds many important applications in quantum information
science and quantum metrology, and has been produced in a variety of physical
systems involving optical nonlinear processes. Here, we show how a nonlinear
magnetostrictive interaction in a ferrimagnet in cavity magnomechanics can be
used to reduce quantum noise of the electromagnetic field. We show optimal
parameter regimes where a substantial and stationary squeezing of the microwave
output field can be achieved. The scheme can be realized within the reach of
current technology in cavity electromagnonics and magnomechanics. Our work
provides a new and practicable approach for producing squeezed vacuum states of
electromagnetic fields, and may find promising applications in quantum
information processing and quantum metrology.
