Classical Field Entanglement of Trapped Polariton Condensates

Abstract

We study the dynamics of two‐bosonic condensates of exciton–polaritons confined in coupled elliptical traps. Within the mean field approximation the system is described by a generalized two‐body Schrödinger equation that accounts for the pumping of polaritons to the coupled condensates from two independent exciton reservoirs. The system is conveniently described by a truncated 4 x 4 density matrix. Applying a pair of control optical pulses, we demonstrate how coherent interactions between the condensates transform the system from an initial separable pure state with zero entanglement (negativity = 0) to an entangled state characterized by negativity close to 0.5. This study underscores the high potentiality of exciton–polariton systems for analog and quantum simulations and paves the way for the realization of ultrafast, many‐body quantum computation platforms.
