Information geometry of density matrices and state estimation
Information geometry density matrices state estimation
2010/10/18
Given a pure state vector |xi and a density matrix ˆρ, the function p(x|ˆρ) = hx|ˆρ|xi defines a probability density on the space of pure states parameterised by density matrices. The a...
