Controlled Quantum Metrology with Anisotropic Heisenberg Spin Interactions under Intrinsic Decoherence
S. K. Singh, Jia-Xin Peng, Y-J Zhu +1
We theoretically investigate quantum parameter estimation in a two-qubit anisotropic Heisenberg spin system with Dzyaloshinskii-Moriya (DM) interaction in the presence of intrinsic…

Estimation theory of photon-magnon coupling strength in a driven-dissipative double-cavity-magnon system
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
Cavity-magnon systems are emerging as a fruitful architecture for the integration of quantum technologies and spintronic technologies, where magnons are coupled to microwave photon…
