Random Party Distillation on a Superconducting Processor
Alexander C. B. Greenwood, Jackson Russett, Hoi-Kwong Lo +1
Random party distillation refers to the process by which Einstein-Podolsky-Rosen pairs are probabilistically extracted from a single copy of a multipartite entangled state after mu…
Mitigating Phase Correlations in Quantum Key Distribution Using Path-Selection Modulation
Amita Gnanapandithan, Li Qian, Hoi-Kwong Lo
Phase correlations are an under-explored vulnerability in QKD. Here, we present an experimental and simulated characterization of correlations arising from electro-optic phase enco…
Long-fiber Sagnac interferometers for twin field quantum key distribution networks
Reem Mandil, Li Qian, Hoi-Kwong Lo
A Sagnac loop structure can help overcome the major difficulty in the practical implementation of a twin field quantum key distribution (TFQKD) network, namely, the need to stabili…
Hidden multi-dimensional modulation side channels in quantum protocols
Amita Gnanapandithan, Li Qian, Hoi-Kwong Lo
Quantum protocols including quantum key distribution and blind quantum computing often require the preparation of quantum states of known dimensions. Here, we show that, rather sur…
