Multi-terminal topological devices are a new generation of electronic devices with quantized properties robust against imperfections. In magnetic topological insulators, dissipationless 1D chiral edge states give functional devices in zero magnetic field, of interest for quantum metrology or topological electronics. Here, we show that simple quantum circuits (disk and rings) with non-Hermitian topology, based on the interconnection of Chern states in the quantum anomalous Hall regime, can have a much stronger quantization of their invariant than that of the Chern invariant itself, when measured in a non-metrology grade setup, that is, in industry-relevant conditions. Remarkably, the chirality-related non-Hermitian skin effect shows a record degree of localization for a quantum Hall device. This new type of topological quantum device based on magnets can operate at liquid-helium temperature with a good quantization and have some potential as cryogenic sensors for applications in high-precision impedance or magnetic field measurements.
