Jess Riedel

Scientist

Jess Riedel studies decoherence and the quantum-classical transition. He is especially interested in defining and efficiently identifying wavefunction “branches” in out-of-equilibrium many-body systems. These quasi-classical components can be characterized by the presence of spatially disjointed redundant information, and classically sampling from them may speed up real-time tensor-network simulations. In the past, he studied the sensitivity of massive superpositions to very small momentum transfers, especially as a way to use matter interferometers to detect MeV-scale dark matter.
