Quantum Metrology with Coherent Superposition of Two Different Coded Channels
Dong Xie, Chunling Xu, An Min Wang
We investigate the advantage of coherent superposition of two different coded channels in quantum metrology. In a continuous variable system, we show that the Heisenberg limit $1/N…

Parameter estimation and quantum entanglement in PT symmetrical cavity magnonics system
Dong Xie, Chunling Xu, An min Wang
We investigate the parameter estimation in a magnon-cavity-magnon coupled system. PT symmetrical two magnons system can be formed in the gain magnetic materials by the adiabatic el…
