Synthesizing In-Bulk Topological Corner States via Giant Atoms
Zhao-Min Gao, Xin Wang
Corner states in higher-order topological insulators are typically confined to geometric corners, limiting their flexibility for scalable quantum information processing. We propose…
Amplifying Decoherence-Free Many-Body Interactions with Giant Atoms Coupled to Parametric Waveguide
Xin Wang, Zhao-Min Gao
Parametric amplification offers a powerful means to enhance quantum interactions through field squeezing, yet it typically introduces additional noise which accelerates quantum dec…
Harnessing spontaneous emission of correlated photon pairs from ladder-type giant atoms
Zhao-Min Gao, Jia-Qi Li, Ying-Huan Wu +2
The realization of correlated multi-photon processes usually depends on the interaction between nonlinear media and atoms. However, the nonlinearity of optical materials is general…
Circuit QED with a Giant Atom Coupling to Left-handed Superlattice Metamaterials
Zhao-Min Gao, Jia-Qi Li, Zi-Wen Li +2
Giant atoms, where the dipole approximation ceases to be valid, allow us to observe unconventional quantum optical phenomena arising from interference and time-delay effects. Most…
