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{…
Experimental verification of the steering ellipsoid zoo via two-qubit states
Kai Xu, Lijun Liu, Ning-Ning Wang +6
Quantum steering ellipsoid visualizes the set of all qubit states that can be steered by measuring on another correlated qubit in the Bloch picture. Together with local reduced sta…
Tripartite entanglement measure under local operations and classical communication
Xiaozhen Ge, Lijun Liu, Shuming Cheng
Multipartite entanglement is an indispensable resource in quantum communication and computation, however, it is a challenging task to faithfully quantify this global property of mu…
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…
Recycling qubits for the generation of Bell nonlocality between independent sequential observers
Shuming Cheng, Lijun Liu, Travis J. Baker +1
There is currently much interest in the recycling of entangled systems, for use in quantum information protocols by sequential observers. In this work, we study the sequential gene…
Limitations on sharing Bell nonlocality between sequential pairs of observers
Shuming Cheng, Lijun Liu, Travis J. Baker +1
We give strong analytic and numerical evidence that, under mild measurement assumptions, two qubits cannot both be recycled to generate Bell nonlocality between multiple independen…
Monogamy relations for nonclassical correlations of multi-qubit states
Shuming Cheng, Lijun Liu
Nonclassical correlations have been found useful in many quantum information processing tasks, and various measures have been proposed to quantify these correlations. In this work,…
Real-time Information, Uncertainty and Quantum Feedback Control
Bo Qi, Daoyi Dong, Chunlin Chen +2
Feedback is the core concept in cybernetics and its effective use has made great success in but not limited to the fields of engineering, biology, and computer science. When feedba…
High Precision Inertial Rotation Rate and Magnetic Field Estimate via Extended Kalman Filter
Lijun Liu, Bo Qi, Shuming Cheng +1
Recent developments of technology have enabled atomic spins as the most sensitive inertial and magnetic sensors. Atomic spin gyroscope (magnetometer) essentially outputs the estima…
