Topology Bench: Systematic Graph Based Benchmarking for Core Optical Networks
Robin Matzner, Akanksha Ahuja, Rasoul Sadeghi +4
Topology Bench is a comprehensive topology dataset designed to accelerate benchmarking studies in optical networks. The dataset, focusing on core optical networks, comprises public…
Gaussian Process-Driven History Matching for Physical Layer Parameter Estimation in Optical Fiber Communication Networks
Josh W. Nevin, Sam Nallaperuma, Seb J. Savory
We present a methodology for the estimation of optical network physical layer parameters from signal to noise ratio via history matching. An expensive network link simulator is emu…
Perturbation-based Frequency Domain Linear and Nonlinear Noise Estimation
F. J. Vaquero-Caballero, D. J. Ives, S. J. Savory
In this paper, a new method for the separation of noise categories based on Four-Wave Mixing is presented. The theoretical analysis is grounded in the Gaussian Noise model and veri…
Transceiver Noise Characterization based on Perturbations
F. J. Vaquero-Caballero, D. J. Ives, S. J. Savory
In this paper, we discuss a new technique for measuring transceiver noise, skew, and for the detection of uncompensated transceiver impairments. The method consists on the introduc…
In-band Perturbation based OSNR Estimation
F. J. Vaquero-Caballero, D. Charlton, M. E. Mousa-Pasandi +6
Perturbed spectra are modelled to estimate OSNR for a single channel amplified link. Perturbation-dependent nonlinear noise is separated from constant ASE noise using a set of prop…
A direct GHz-clocked phase and intensity modulated transmitter applied to quantum key distribution
G. L. Roberts, M. Lucamarini, J. F. Dynes +3
Quantum key distribution (QKD), a technology that enables perfectly secure communication, has evolved to the stage where many different protocols are being used in real-world imple…
Manipulating photon coherence to enhance the security of practical quantum key distribution
George L. Roberts, Marco Lucamarini, James F. Dynes +3
Quantum key distribution (QKD) allows two users to communicate with theoretically provable secrecy by encoding information on photonic qubits. Current encoders are complex, however…
Modulator-free coherent-one-way quantum key distribution
George L. Roberts, Marco Lucamarini, James F. Dynes +3
Time-bin encoding is an attractive method for transmitting photonic qubits over long distances with minimal decoherence. It allows a simple receiver for quantum key distribution (Q…
Why compensating fibre nonlinearity will never meet capacity demands
Domanic Lavery, Robert Maher, David Millar +3
Current research efforts are focussed on overcoming the apparent limits of communication in single mode optical fibre resulting from distortion due to fibre nonlinearity. It has be…
The Benefit of Split Nonlinearity Compensation for Optical Fiber Communications
Domanic Lavery, David Ives, Gabriele Liga +3
In this Letter we analyze the benefit of digital compensation of fiber nonlinearity, where the digital signal processing is divided between the transmitter and receiver. The applic…
On the Impact of Optimal Modulation and FEC Overhead on Future Optical Networks
Alex Alvarado, David J. Ives, Seb Savory +1
The potential of optimum selection of modulation and forward error correction (FEC) overhead (OH) in future transparent nonlinear optical mesh networks is studied from an informati…
Quantum Communication
Nicolas Gisin
Quantum Communication is the art of transferring an unknown quantum state from one location, Alice, to a distant one, Bob. This is a non-trivial task because of the quantum no-clon…
Design and optimisation of quantum logic circuits for a three-qubit Deutsch-Jozsa algorithm implemented with optically-controlled, solid-state quantum logic gates
A. Del Duce, S. Savory, P. Bayvel
We analyse the design and optimisation of quantum logic circuits suitable for the experimental demonstration of a three-qubit quantum computation prototype based on optically-contr…
