Gouy Phase Radial Mode Sorter for Light: Concepts and Experiments
Xuemei Gu, Mario Krenn, Manuel Erhard +1
We present an in principle lossless sorter for radial modes of light, using accumulated Gouy phases. The experimental setups have been found by a computer algorithm, and can be int…
Twisted Photons: New Quantum Perspectives in High Dimensions
Manuel Erhard, Robert Fickler, Mario Krenn +1
Quantum information science and quantum information technology have seen a virtual explosion world-wide. It is all based on the observation that fundamental quantum phenomena on th…
Experimental GHZ Entanglement beyond Qubits
Manuel Erhard, Mehul Malik, Mario Krenn +1
The Greenberger-Horne-Zeilinger (GHZ) argument provides an all-or-nothing contradiction between quantum mechanics and local-realistic theories. In its original formulation, GHZ inv…
Quantum gate description for induced coherence without induced emission and related phenomena
Sahar Alipour, Mario Krenn, Anton Zeilinger
We introduce unitary quantum gates for photon pair creation in spontaneous parametric down-conversion nonlinear crystals (NLs) and for photon path alignment. These are the two key…
Generation of the Complete Four-dimensional Bell Basis
Feiran Wang, Manuel Erhard, Amin Babazadeh +3
The Bell basis is a distinctive set of maximally entangled two-particle quantum states that forms the foundation for many quantum protocols such as teleportation, dense coding and…
Active learning machine learns to create new quantum experiments
Alexey A. Melnikov, Hendrik Poulsen Nautrup, Mario Krenn +4
How useful can machine learning be in a quantum laboratory? Here we raise the question of the potential of intelligent machines in the context of scientific research. A major motiv…
