Ansatz-Free Hamiltonian Learning with Heisenberg-Limited Scaling

Journal Article Prx Quantum · October 22, 2025 Learning the unknown interactions that govern a quantum system is crucial for quantum information processing, device benchmarking, and quantum sensing. The problem, known as Hamiltonian learning, is well understood under the assumption that interactions ar ... Full text Cite

Fast Mixing of Weakly Interacting Fermionic Systems at Any Temperature

Journal Article Prx Quantum · July 1, 2025 We study the mixing time of a recently proposed efficiently implementable Lindbladian designed to prepare the Gibbs states in the setting of weakly interacting fermionic systems. We show that at any temperature, the Lindbladian spectral gap for even parity ... Full text Cite

Mixing Time of Open Quantum Systems via Hypocoercivity.

Journal Article Physical review letters · April 2025 Understanding the mixing of open quantum systems is a fundamental problem in physics and quantum information science. Existing approaches for estimating the mixing time often rely on the spectral gap estimation of the Lindbladian generator, which can be ch ... Full text Cite
