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…
Enhanced Quantum Metrology with Non-Phase-Covariant Noise
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
The detrimental impact of noise on sensing performance in quantum metrology has been widely recognized by researchers in the field. However, there are no explicit fundamental laws…
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…
