Abstract

We introduce a general scheme for increasing secure key rates in entanglement-based cryptography exploiting multiple degrees of freedom. We experimentally exemplify this scheme through spatial and wavelength multiplexing. Scalability of our approach is demonstrated.

Experimental wavelength-multiplexed entanglement-based quantum cryptography

Abstract In state-of-the-art quantum key distribution systems, the main limiting factor in increasing the key generation rate is the timing resolution in detecting photons. Here, we present and experimentally demonstrate a strategy to overcome this limitation, also for high-loss and long-distance implementations. We exploit the intrinsic wavelength correlations of entangled photons using wavelength multiplexing to generate a quantum secure key from polarization entanglement. The presented approach can be integrated into both fiber- and satellite-based quantum-communication schemes, without any changes to most types of entanglement sources. This technique features a huge scaling potential allowing to increase the secure key rate by several orders of magnitude as compared to non-multiplexed schemes.

Implementation of multiplexing in a subcarrier-wave quantum cryptography system

Quantum cryptography allows distributing secure keys in a way that any eavesdropping in the channel is inevitably detected. This work is dedicated to introducing wavelength division multiplexing in a subcarrier-wave quantum cryptography system. Compared to other existing schemes, the resulting device is able to achieve higher bitrates (up to 2.26 Mbit/s at 20 km), is robust against external conditions and compatible with standard telecommunication fibres in multi-user environment.

The security of quantum key distribution using the orbital angular momentum states of light

Eliot Bolduc, Jonathan Leach, Daniel J. Gauthier +1 more

High-dimensional entanglement is a key resource for quantum cryptography. We experimentally realise the criterion for secure quantum key distribution when using photons entangled in the orbital angular momentum and angle degrees of freedom.
