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…
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…
