Language Diversity of Measured Quantum Processes
Karoline Wiesner, James P. Crutchfield
The behavior of a quantum system depends on how it is measured. How much of what is observed comes from the structure of the quantum system itself and how much from the observer's…
Infinite Correlation in Measured Quantum Processes
Karoline Wiesner, James P. Crutchfield
We show that quantum dynamical systems can exhibit infinite correlations in their behavior when repeatedly measured. We model quantum processes using quantum finite-state generator…
Intrinsic Quantum Computation
James P. Crutchfield, Karoline Wiesner
We introduce ways to measure information storage in quantum systems, using a recently introduced computation-theoretic model that accounts for measurement effects. The first, the q…
Computation in Finitary Stochastic and Quantum Processes
Karoline Wiesner, James P. Crutchfield
We introduce stochastic and quantum finite-state transducers as computation-theoretic models of classical stochastic and quantum finitary processes. Formal process languages, repre…
