Deterministic Single-Phonon Source Triggered by a Single Photon.

摘要: We propose a scheme that enables the deterministic generation of single phonons at gigahertz frequencies triggered by photons in near infrared. This process is mediated quantum dot embedded on chip an optomechanical circuit, which allows for simultaneous control relevant photonic and phononic frequencies. devise new circuit elements constitute necessary building blocks proposed are readily implementable within current state-of-the-art nanofabrication. will open avenues implementing functionalities based as on-chip bus.
