Security of high-dimensional quantum key distribution protocols using Franson interferometers
Thomas Brougham,Stephen M. Barnett,Kevin McCusker,Kevin McCusker,Paul G. Kwiat,Daniel J. Gauthier +5 more
TL;DR: In this paper, the authors show that a single pair of Franson interferometers is not a practical approach to secure high-dimensional energy-time entanglement-based QKD.
Journal ArticleDOI

Jasminder S. Sidhu,Siddarth Koduru Joshi,Mustafa Gündoğan,Thomas Brougham,David Lowndes,Luca Mazzarella,Markus Krutzik,Sonali Mohapatra,Daniele Dequal,Giuseppe Vallone,Paolo Villoresi,Alexander Ling,Thomas Jennewein,Makan Mohageg,John Rarity,Ivette Fuentes,Stefano Pirandola,Daniel K. L. Oi +17 more
TL;DR: In this paper, the authors provide a roadmap of key milestones towards a complete, global quantum networked landscape and summarise important challenges in space quantum technologies that must be overcome and recent efforts to mitigate their effects.
Journal ArticleDOI
Decision and function problems based on boson sampling
TL;DR: The purpose of this work is to investigate whether boson sampling can be used as a resource of decision and function problems that are computationally hard, and may thus have cryptographic applications.
Journal ArticleDOI
Information communicated by entangled photon pairs
TL;DR: A key finding for entanglement-based QKD protocols is that, by using realistic experimental parameters, one can obtain over 10 bits per photon, and it is shown how the results can be applied to characterize the capacity of a fiber array and to quantifyEntanglement using mutual information.
Journal ArticleDOI
Cartesian and polar Schmidt bases for down-converted photons How high dimensional entanglement protects the shared information from non-ideal measurements
TL;DR: In this article, an analytical form of the Schmidt modes of spontaneous parametric down-conversion biphotons in both Cartesian and polar coordinates was derived, which correspond to Hermite-Gauss (HG) or Laguerre Gauss (LG) modes only for a specific value of their width, and how such value depends on the experimental parameters.
