Quantum foundations

A thorough discussion of the similarities and differences between quantum and classical probability, as well as my personal take on the conceptual basis of quantum theory, can be found in

Statistical reconstruction of quantum states

Various techniques for estimating a quantum state based on incomplete or noisy measurement data are discussed in

Random matrices

Probabilistic considerations may pertain not only to the quantum states themselves but also to their time evolution. When the latter is not known with certainty, it may be modeled with random matrices. One example is considered in
