Transient Information Partition in Coherent Exciton-Phonon-Photon Dynamics
Kunio Ishida
We study transient information partition in a coherent exciton-phonon-photon system using subsystem-resolved quantum mutual information (QMI). By employing a model with excitonic,…

Quantum-coherent nonlinear interferometry using electron-phonon systems for entanglement-assisted terahertz sensing
Junya Ogiri, Hiroaki Minamide, Kunio Ishida
We present a theoretical framework for quantum-coherent nonlinear interferometry in which the nonlinear medium is modeled as active electron-phonon quantum systems rather than a pa…
