Heralded non-destructive quantum entangling gate with single-photon sources
Jin-Peng Li, Xuemei Gu, Jian Qin +10
Heralded entangling quantum gates are an essential element for the implementation of large-scale optical quantum computation. Yet, the experimental demonstration of genuine heralde…

Quantum Experiments and Graphs II: Quantum Interference, Computation and State Generation
Xuemei Gu, Manuel Erhard, Anton Zeilinger +1
We present a conceptually new approach to describe state-of-the-art photonic quantum experiments using Graph Theory. There, the quantum states are given by the coherent superpositi…

Quantum Experiments and Graphs: Multiparty States as coherent superpositions of Perfect Matchings
Mario Krenn, Xuemei Gu, Anton Zeilinger
We show a surprising link between experimental setups to realize high-dimensional multipartite quantum states and Graph Theory. In these setups, the paths of photons are identified…
