We prove that the quantum trajectory of repeated perfect measurement on a finite quantum system either asymptotically purifies, or hits upon a family of `dark' subspaces, where the…

Noncommutative continuous Bernoulli shifts
Jürgen Hellmich, Claus Köstler, Burkhard Kümmerer
We introduce a non-commutative extension of Tsirelson-Vershik's noises, called (non-commutative) continuous Bernoulli shifts. These shifts encode stochastic independence in terms o…
