Abstract
Photon-lattice(phonon)coupling is fundamental to light-matter interaction,particularly when it reaches the quantum limit of the phonon-coupled single-photon emission,which holds great potential for quantum manipulation and quantum information transduction.Here,we report single defect state-phonon coupling in hexagonal boron nitride(hBN)at room temperature.An ultrabroad spectrum of single-photon emissions can be achieved by selecting the excitation energies.Using photoluminescence excitation spectroscopy,we observe single-phonon-assisted resonance-enhanced single-photon emission,along with multiple phonon replicas that herald the creation of phonon Fock state.We also develop a transition model to gain insight into the physical process behind the single defect state-phonon coupling.Our work sets the stage for manipulating electron-phonon coupling state with single quantum-level precision at room temperature.
