Niveau: Supérieur, Master
1Quantum measurements in continuous time and non-Markovian evolutions A. Barchielli — Politecnico di Milano & INFN 1) The problem. Connections among master equations, unravelling and observation in continuous time in the Markov and non-Markov cases. 2) From a class of master equations with memory (the Lindblad rate equation — Budini, Breuer, Petruccione...) to a jump/diffusion unravelling with measurement interpretation. An example: the spectrum of a 2-level atom in a structured bath. (work with Pellegrini) 3) From non-Markov stochastic Schrodinger equations to the theory of measurements in continuous time. Possible introduction of coloured noises, measurement based feedback,... (works with Di Tella, Pellegrini, Petruccione, Holevo).
