Photonic realization of a subgraph extraction in a quantum random network
Lijun Xia, Xuemei Gu, Kai Wang +5
Understanding how complex connectivity emerges in networks is a fundamental challenge in classical and quantum science. In classical random networks, complex subgraphs typically re…
Automated discovery of high-probability heralded schemes for path-entangled states
Marcello Armezzani, Colin P. Lualdi, Xuemei Gu +2
Entangled states of light lie at the heart of photonic quantum technologies, from distributed quantum communication to quantum-enhanced measurement and information processing. Thei…
Analytical Fock Representation of Two-Mode Squeezing for Quantum Interference
Xuemei Gu, Carlos Ruiz-Gonzalez, Mario Krenn
Two-mode squeezing is central to entangled-photon generation and nonlinear interferometry, yet standard perturbative low-gain treatments and Gaussian formalisms can obscure the int…
Automated discovery of high-dimensional multipartite entanglement with photons that never interacted
Sören Arlt, Mario Krenn, Xuemei Gu
Quantum entanglement across spatially separated network nodes is conventionally established through the distribution of photons from a common source or via entanglement swapping th…
Towards autonomous quantum physics research using LLM agents with access to intelligent tools
Sören Arlt, Xuemei Gu, Mario Krenn
Artificial intelligence (AI) is used in numerous fields of science, yet the initial research questions and targets are still almost always provided by human researchers. AI-generat…
Automated Discovery of Non-local Photonic Gates
Sören Arlt, Mario Krenn, Xuemei Gu
Interactions between quantum systems enable quantum gates, the building blocks of quantum information processing. In photonics, direct photon-photon interactions are too weak to be…
