Bilateral photon emission from a vibrating mirror and multiphoton entanglement generation
arxiv(2024)
摘要
Entanglement plays a crucial role in the development of quantum-enabled
devices. One significant objective is the deterministic creation and
distribution of entangled states, achieved, for example, through a mechanical
oscillator interacting with confined electromagnetic fields. In this study, we
explore a cavity resonator containing a two-sided perfect mirror. Although the
mirror separates the cavity modes into two independent confined electromagnetic
fields, the radiation pressure interaction gives rise to high-order effective
interactions across all subsystems. Depending on the chosen resonant
conditions, which are also related to the position of the mirror, we study
2n-photon entanglement generation and bilateral photon pair emission.
Demonstrating the non-classical nature of the mechanical oscillator, we provide
a pathway to control these phenomena, opening potential applications in quantum
technologies. Looking ahead, similar integrated devices could be used to
entangle subsystems across vastly different energy scales, such as microwave
and optical photons.
