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…
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…
High-Dimensional Single-Photon Quantum Gates: Concepts and Experiments
Amin Babazadeh, Manuel Erhard, Feiran Wang +4
Transformations on quantum states form a basic building block of every quantum information system. From photonic polarization to two-level atoms, complete sets of quantum gates for…
