This research demonstrates how Cr-doped quantum anomalous Hall insulators enable one-way signal flow in chip-scale devices without requiring external magnetic fields. By leveraging high-impedance plasmon modes, the study achieves strong asymmetric coupling between resonators, a critical step toward nonreciprocal electronics at quantum-classical interfaces.

Quantum Hall insulator links resonators for one-way signal flow

Quantum ZeitgeistSeptember 28, 20266 min read

The chiral nature of the edge magnetoplasmon makes it a promising candidate for advancing chip-scale nonreciprocal devices at quantum-classical interfaces, and quantum anomalous Hall (QAH) materials offer distinct advantages, such as maintaining a stable number of edge channels across a broad range of applied magnetic fields, including zero magnetic field. Cr-doped QAH insulator provides a promising platform for realizing strong plasmon-photon interactions, with an impedance of and a Chern number.

Cr-doped quantum anomalous Hall (QAH) insulators are emerging as key components for directing one-way flow of signals in future circuits. This design uses the unique properties of QAH materials, which maintain stable edge channels even without an applied magnetic field, and opens opportunities for stronger plasmon-photon interactions due to a high-impedance plasmon mode. A high-impedance plasmon mode, exhibiting a Chern number, within quantum anomalous Hall (QAH) materials markedly amplifies electric-dipole coupling to nearby quantum emitters; this characteristic makes these materials ideal for strong asymmetric plasmon-photon coupling and potential applications in nonreciprocal electronics. The impedance of this mode reaches, a value that directly influences the scale of zero-point voltage fluctuations and, consequently, the strength of the interaction with quantum…
