Description
Tianyu Qian and a large team run a non-Hermitian atomic magnetometer on programmable digital electronics, in work from twenty twenty-six. Exceptional points promise sharper sensing but are hard to hold steady. Tiny disturbances knock real devices off those special points. A hybrid design builds the non-Hermitian part in software instead. Digital control then creates and tunes exceptional points on demand.
Coupling the electronics to an atomic magnetometer boosts weak-field sensitivity. The measured gain reaches over four times the plain sensor response. A linear sensor response converts into a stronger sublinear one near the point. Modular design lets other physical sensors plug into the same scheme. Atomic physics, electronics, and non-Hermitian design meet in one device. Programmable exceptional points could spread to many sensor types.
