Cavity-Mediated Molecular Entanglement and Generation of Non-classical States of Light

The
generation and control of entanglement in a quantum
mechanical
system are critical elements of nearly all quantum applications. Molecular
systems are promising candidates, with numerous degrees of freedom
able to be targeted. However, knowledge of intersystem entanglement
mechanisms in such systems is limited. In this work, we demonstrate
the generation of entanglement between vibrational degrees of freedom
in molecules via strong coupling to a cavity mode driven by a weak
coherent field. In a bimolecular system, we show that entanglement
can be generated not only between the cavity and molecular system
but also between molecules. This process also results in the generation
of nonclassical states of light, providing potential pathways for
harnessing entanglement in molecular systems.
