Quantum Experiments and Graphs III: High-Dimensional and Multi-Particle Entanglement
Xuemei Gu, Lijun Chen, Anton Zeilinger +1
Quantum entanglement plays an important role in quantum information processes, such as quantum computation and quantum communication. Experiments in laboratories are unquestionably…
Arbitrary d-dimensional Pauli X-Gates of a flying Qudit
Xiaoqin Gao, Mario Krenn, Jaroslav Kysela +1
High-dimensional degrees of freedom of photons can encode more quantum information than their two-dimensional counterparts. While the increased information capacity has advantages…
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…
On Small Beams with Large Topological Charge II: Photons, Electrons and Gravitational Waves
Mario Krenn, Anton Zeilinger
Beams of light with a large topological charge significantly change their spatial structure when they are focused strongly. Physically, it can be explained by an emerging electroma…
