Programmable Heisenberg-limit sensor from a nonlinear quantum energy pump
Yang Peng
We introduce a programmable Heisenberg-limited bosonic quantum sensor based on a nonlinear quantum energy pump, implemented with a Kerr-nonlinear resonator coupled to multiple high…
Work Statistics of Autonomous Quantum Energy Pumps
Yang Peng
We develop a terminal-resolved theory of work statistics for autonomous quantum energy pumps. By modeling the systems that supply and receive energy as explicit quantum terminals,…
Universal Neural Propagator: Learning Time Evolution in Many-Body Quantum Systems
Zihao Qi, Christopher Earls, Yang Peng
Conventional approaches to simulating quantum many-body dynamics produce a single trajectory: if the Hamiltonian or the initial state is changed, the computation must be re-perform…
Neural Operator Quantum State: A Foundation Model for Quantum Dynamics
Zihao Qi, Christopher Earls, Yang Peng
Capturing the dynamics of quantum many-body systems under time-dependent driving protocols is a central challenge for numerical simulations. Existing methods such as tensor network…
