Physics-Informed Neural Networks with Adaptive Constraints for Multi-Qubit Quantum Tomography
Changchun Feng, Laifa Tao, Lin Chen
Quantum state tomography (QST) faces exponential measurement requirements and noise sensitivity in multi-qubit systems, bottlenecking practical quantum technologies. We present a p…
Machine Learning Framework for Efficient Prediction of Quantum Wasserstein Distance
Changchun Feng, Xinyu Qiu, Laifa Tao +1
The quantum Wasserstein distance (W-distance) is a fundamental metric for quantifying the distinguishability of quantum operations, with critical applications in quantum error corr…
Coherence and entanglement in Grover and Harrow-Hassidim-Lloyd algorithm
Changchun Feng, Lin Chen, Lijun Zhao
Coherence, discord and geometric measure of entanglement are important tools for measuring physical resources. We compute them at every steps of the Grover's algorithm. We summariz…
Inertia of two-qutrit entanglement witnesses
Changchun Feng, Lin Chen, Chang Xu +1
Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We investigate the inertias of bipartite EWs constructed by the partial transpose of NPT stat…
