Estimation of a sparse multi-qubit Hamiltonian via compressed sensing
Juntao Tu, Yuanlong Wang, Shuming Cheng +2
Hamiltonian estimation is an effective approach in studying the structure and dynamical evolution of quantum systems. The difficulty in estimating the Hamiltonian is that an -qu…
Intensity-guided pose-free multiview fusion for single photon sensing
Jinyi Liu, Lijun Liu, Shuming Cheng +3
Single-photon light detection and ranging (LiDAR) extends active three-dimensional sensing at the fundamental level and has found applications in extreme environments involving lon…
Point upsampling networks for single-photon sensing
Jinyi Liu, Guoyang Zhao, Lijun Liu +3
Single-photon sensing has generated great interest as a prominent technique of long-distance and ultra-sensitive imaging, however, it tends to yield sparse and spatially biased poi…
The boundary of Kirkwood-Dirac quasiprobability
Lijun Liu, Shuming Cheng
The Kirkwood-Dirac (KD) quasiprobability describes measurement statistics of joint quantum observables, and has generated great interest as prominent indicators of non-classical fe…
