Quantum Fisher Information and Its Application in Channel Estimation and Quantum Phase Transition
Speaker: Dr. Qiang Zheng(郑强), Beijing Computational Science Research Center
Abstract: Quantum Fisher information(QFI) is one key quantity in quantum metrology and quantum information. In this talk, I will first discuss some ABC of QFI. Then, I will discuss our recently studies on this topics: estimation of the quantum channel by the dynamcis of QFI and detecting the QPT of spin-chain.
