State Diagnostics of Complexity in Open Quantum Systems
Komal Sah, Fabio Anza, Alexandra M. Jurgens +1
We study the emergence of complexity in finite-size quantum systems as their dynamics transition from closed and coherent evolution to interacting and effectively open behavior. Us…
Learning Orthogonal Random Unitary Channels with Contracted Quantum Approaches and Simplex Optimization
Scott E. Smart, Alexander Jürgens, Joseph Peetz +1
Random (mixed) unitary channels describe an important subset of quantum channels, which are commonly used in quantum information, noise modeling, and quantum error mitigation. Desp…
Measurement-Induced Randomness and Structure in Controlled Qubit Processes
Ariadna E. Venegas-Li, Alexandra M. Jurgens, James P. Crutchfield
When an experimentalist measures a time series of qubits, the outcomes generate a classical stochastic process. We show that measurement induces high complexity in these processes…
