Almost-idempotent quantum channels and approximate -algebras
Alexei Kitaev
Let be a unital completely positive (UCP) map on the space of operators on some Hilbert space. We assume that is -idempotent, namely, $\|Φ^2-Φ\|_{\mathrm{cb}} \leη…

Thermalization and Criticality on an Analog-Digital Quantum Simulator
Trond I. Andersen, Nikita Astrakhantsev, Amir H. Karamlou +224
Understanding how interacting particles approach thermal equilibrium is a major challenge of quantum simulators. Unlocking the full potential of such systems toward this goal requi…
