Coherent control in the ground and optically excited state of an ensemble of erbium dopants

Pablo Cova Fariña, Benjamin Merkel, Natalia Herrera Valencia +3

Ensembles of erbium dopants can realize quantum memories and frequency converters that operate in the minimal-loss wavelength band of fiber optical communication. Their operation r…

Entangled ripples and twists of light: Radial and azimuthal Laguerre-Gaussian mode entanglement

Natalia Herrera Valencia, Vatshal Srivastav, Saroch Leedumrongwatthanakun +2

It is well known that photons can carry a spatial structure akin to a "twisted" or "rippled" wavefront. Such structured light fields have sparked significant interest in both class…

High-Dimensional Pixel Entanglement: Efficient Generation and Certification

Natalia Herrera Valencia, Vatshal Srivastav, Matej Pivoluska +4

Photons offer the potential to carry large amounts of information in their spectral, spatial, and polarisation degrees of freedom. While state-of-the-art classical communication sy…

Semi-Device-Independent Random Number Generation with Flexible Assumptions

Matej Pivoluska, Martin Plesch, Máté Farkas +6

Our ability to trust that a random number is truly random is essential for fields as diverse as cryptography and fundamental tests of quantum mechanics. Existing solutions both com…

Measuring azimuthal and radial modes of photons

Frédéric Bouchard, Natalia Herrera Valencia, Florian Brandt +3

With the emergence of the field of quantum communications, the appropriate choice of photonic degrees of freedom used for encoding information is of paramount importance. Highly pr…
