Efficient fidelity estimation:alternative derivation and related applications
《Communications in Theoretical Physics》2024年第9期16-20,共5页Diego S Starke Marcos L W Basso Jonas Maziero 
In[Phys.Rev.A 107012427(2023)],Baldwin and Jones prove that Uhlmann–Jozsa’s fidelity between two quantum statesρandσ,i.e.,F(ρ,σ)=(Tr√√ρσ√ρ)^(2),can be written in a simplified form as F(ρ,σ)=(Tr√ρσ)^(2...

cluster expansion Mayer series canonical ensemble grand canonical ensemble
《Communications in Theoretical Physics》2016年第2期185-188,共4页王先智 
Mayer derived the Mayer series from both the canonical ensemble and the grand canonical ensemble by use of the cluster expansion method. In 2002, we conjectured a recursion formula of the canonical partition function ...
