Abstract
Circuit quantum electrodynamics architecture provides a controllable artificial system and enriches the physics with the participation of electron-photon interaction. The cover shows this hybrid architecture comprised of a superconducting microwave resonator and a triple quantum dot. In article number 2100104, Si-Si Gu and colleagues investigate quantum cellular automata and “photon-assisted” quadruple point phenomena in this system, which involve the Coulomb interaction among multiple dots and the simultaneously-tunneling processes assisted with cavity photons. These results suggest that this hybrid system has the potential for studying exotic many-body effects and electron-photon interaction.
