A Variational Approach to Unique Determinedness in Pure-state Tomography
Chao Zhang, Xuanran Zhu, Bei Zeng
In pure-state tomography, the concept of unique determinedness (UD) -- the ability to uniquely determine pure states from measurement results -- is crucial. This study presents a n…
Unified Quantum State Tomography and Hamiltonian Learning Using Transformer Models: A Language-Translation-Like Approach for Quantum Systems
Zheng An, Jiahui Wu, Muchun Yang +2
Schrödinger's equation serves as a fundamental component in characterizing quantum systems, wherein both quantum state tomography and Hamiltonian learning are instrumental in compr…
A ZX-Calculus Approach for the Construction of Graph Codes
Zipeng Wu, Song Cheng, Bei Zeng
Quantum Error-Correcting Codes (QECCs) play a crucial role in enhancing the robustness of quantum computing and communication systems against errors. Within the realm of QECCs, sta…
Detecting Entanglement by Pure Bosonic Extension
Xuanran Zhu, Chao Zhang, Chenfeng Cao +3
In the realm of quantum information theory, the detection and quantification of quantum entanglement stand as paramount tasks. The relative entropy of entanglement (REE) serves as…
Maximum entropy methods for quantum state compatibility problems
Shi-Yao Hou, Zipeng Wu, Jinfeng Zeng +4
Inferring a quantum system from incomplete information is a common problem in many aspects of quantum information science and applications, where the principle of maximum entropy (…
