Square matrices with integer eigenvalues under entry permutations
Shuming Cheng, Siran Zhang
We investigate the problem of which multisets of integer entries yield integer eigenvalues in every square matrix arrangement? Combining module reduction with a dyadic criterion fo…
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 pairwise registration for single-photon view fusion
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…
The polygon relation and subadditivity of entropic measures for discrete and continuous multipartite entanglement
Lijun Liu, Xiaozhen Ge, Shuming Cheng
In a recent work [Ge {\it et al.}, arXiv: 2312. 17496 (2023)], we have derived the polygon relation of bipartite entanglement measures that is useful to reveal the entanglement pro…
Faithful geometric measures for genuine tripartite entanglement
Xiaozhen Ge, Lijun Liu, Yong Wang +4
We present a faithful geometric picture for genuine tripartite entanglement of discrete, continuous, and hybrid quantum systems. We first find that the triangle relation $\mathcal{…
Efficient factored gradient descent algorithm for quantum state tomography
Yong Wang, Lijun Liu, Shuming Cheng +2
Reconstructing the state of quantum many-body systems is of fundamental importance in quantum information tasks, but extremely challenging due to the curse of dimensionality. In th…
