Abstract: We investigate the use of high-dimensional quantum key distribution (HD-QKD) in wireless access to hybrid quantum classical networks. We study the distribution of d-dimensional time-phase encoded states between an indoor wireless user and the central office on the other end of the access network. We evaluate the performance in the case of transmitting quantum and classical signals over the same channel by accounting for the impact of background noise induced by the Raman-scattered light on the QKD receiver. We also take into account the loss and background noise that occur in indoor environments as well as finite key effects in our analysis. We show that an HD-QKD system with d = 4 can outperform its qubit-based counterpart.

Deep-Learning-Based Radio-Frequency Side-Channel Attack on Quantum Key Distribution [0.0]
Quantum key distribution (QKD) protocols are proven secure based on fundamental physical laws. Side channels, where the encoded quantum state is correlated with properties of other degrees of freedom of the quantum channel, allow an eavesdropper to obtain information unnoticeably. We here demonstrate a side-channel attack using a deep convolutional neural network to analyze the recorded classical, radio-frequency electromagnetic emissions.
