Front Cover: Characterization of a Triple Quantum Dot via an On‐chip Microwave Resonator (Adv. Quantum Technol. 2/2022). Issue 2 (9th February 2022) - Gu, Si‐Si
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.
