Abstract: M06.00009 : Photoninduced quantum entanglement between remote electron-phonon systems*
(National Institute of Technology, Sendai College)
Dynamical control of quantum entanglement by external light is an intriguing problem which is of importance in the study of light-matter interaction as well as quantum information processing. Recent experiments have shown that phonons created between remote samples are entangled by laser pulses, which shows that the quantum-mechanical nature of light plays a key role to understand the dynamics of quantum correlation between noninteracting systems. In this paper we discuss the dynamics of entanglement creation in remote electron-phonon systems which is mediated by irradiation of quantized light. A multimode spin-boson model is used to describe photons and phonons coupled with two-level systems, and we discuss the quantitative properties of quantum entanglement between photons and/or phonons revealed by numerical calculations.
