Characterization of high-dimensional entangled systems via mutually unbiased measurements
D. Giovannini, J. Romero, J. Leach +3
Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems…
Increasing the dimension in high-dimensional two-photon orbital angular momentum entanglement
J. Romero, D. Giovannini, S. Franke-Anold +2
Any practical experiment utilising the innate D-dimensional entanglement of the orbital angular momentum (OAM) state space of photons is subject to the modal capacity of the detect…
Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks
D. Giovannini, F. M. Miatto, J. Romero +3
The Shannon dimensionality of orbital angular momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers. We…
