- Abstract: Quantum entanglement is a crucial resource for a wide variety of quantum
technologies. However, the current state-of-art methods to generate quantum
entanglement in optomechanical systems are not as efficient as all-optical
methods utilizing nonlinear crystals. This article proposes a new scheme in
which two single-mode squeezed light fields are injected into an optomechanical
cavity. We demonstrate through our numerical simulations that the quantum
entanglement can be substantially enhanced with the careful selection of
squeezing strength and squeezing angle of the two quadrature squeezed light
fields. Our results represent a significant improvement in output bipartite
photon-photon entanglement over the previously demonstrated schemes using two
coherent light fields as inputs. These simulations predict a maximum increase
in bipartite optical entanglement by a factor of about 6, as well as increases
in the quantum noise of the output light. A perceived loss of quantum
information at certain squeezing angles is attributed to tripartite
entanglement between the two optical fields and the optomechanical oscillator
(OMO). At particular squeezing angles, the bipartite (or tripartite)
entanglement can be increased, thus introducing a method of optically
controlling the intracavity entanglement. These mechanics can benefit various
optical quantum technologies utilizing optomechanical entanglement and
continuous variable quantum optics.
