Finding Gaussian Structure in Bosonic States
Alvan Arulandu, Sitan Chen, Ziyun Chen +2
We study agnostic tomography of pure bosonic Gaussian states: given copies of an arbitrary -mode bosonic state , the goal is to output a pure Gaussian state whose infidelity…

Out-of-control Hamiltonian Learning
Weiyuan Gong, Muzhou Ma, Sitan Chen +2
Learning the Hamiltonian of a many-body system from its dynamics is a central task in quantum science, yet the algorithms with the strongest provable guarantees assume some level o…

Online Shadow Tomography Matching the Classical Bounds
Sitan Chen, Ryan O'Donnell, Angelos Pelecanos +1
In Online Shadow Tomography, we are given copies of an unknown -dimensional quantum state , an adversary (adaptively) proposes a sequence of bounded observables $A^{(1)},\ldo…
