Compressed sensing of twisted photons
F. Bouchard, D. Koutny, F. Hufnagel +8
The ability to completely characterize the state of a quantum system is an essential element for the emerging quantum technologies. Here, we present a compressed-sensing inspired m…
Adaptive compressive tomography with no a priori information
D. Ahn, Y. S. Teo, H. Jeong +8
Quantum state tomography is both a crucial component in the field of quantum information and computation, and a formidable task that requires an incogitably large number of measure…
Spin constrained orbital angular momentum control in high-harmonic generation
F. Kong, C. Zhang, H. Larocque +7
The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscop…
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…
Quantum process tomography of a high-dimensional quantum communication channel
Frédéric Bouchard, Felix Hufnagel, Dominik Koutný +5
The characterization of quantum processes, e.g. communication channels, is an essential ingredient for establishing quantum information systems. For quantum key distribution protoc…
Round-Robin Differential Phase-Shift Quantum Key Distribution with Twisted Photons
Frédéric Bouchard, Alicia Sit, Khabat Heshami +2
Quantum key distribution (QKD) offers the possibility for two individuals to communicate a securely encrypted message. From the time of its inception in 1984 by Bennett and Brassar…
