Cluster-correlation expansion for studying decoherence of clock transitions in spin baths
Geng-Li Zhang, Wen-Long Ma, Ren-Bao Liu
The clock transitions (CTs) of central spins have long coherence times because their frequency fluctuations vanish in the linear order of external field noise (such as Overhauser f…

Observation of exceptional point in a PT broken non-Hermitian system simulated using a quantum circuit
Geng-Li Zhang, Di Liu, Xi-Ming Wang +1
Exceptional points (EPs), the degeneracy point of non-Hermitian systems, have recently attracted great attention after its ability to greatly enhance the sensitivity of micro-cavit…

Hyperfine spectroscopy in a quantum-limited spectrometer
S. Probst, G. L. Zhang, M. Rančić +12
We report measurements of electron spin echo envelope modulation (ESEEM) performed at millikelvin temperatures in a custom-built high-sensitivity spectrometer based on superconduct…
