Continuous-variable measurement-device-independent quantum key distribution with photon subtraction

HX Ma, P Huang, DY Bai, SY Wang, WS Bao, GH Zeng - Physical Review A, 2018 - APS
It has been found that non-Gaussian operations can be applied to increase and distill
entanglement between Gaussian entangled states. We show the successful use of the non …

Finite-size analysis of measurement-device-independent quantum cryptography with continuous variables

P Papanastasiou, C Ottaviani, S Pirandola - Physical Review A, 2017 - APS
We study the impact of finite-size effects on the key rate of continuous-variable (CV)
measurement-device-independent (MDI) quantum key distribution (QKD), considering two …

Modular network for high-rate quantum conferencing

C Ottaviani, C Lupo, R Laurenza… - Communications …, 2019 - nature.com
One of the main open problems in quantum communication is the design of efficient
quantum-secured networks. This is a challenging goal, because it requires protocols that …

Gaussian two-mode attacks in one-way quantum cryptography

C Ottaviani, S Mancini, S Pirandola - Physical Review A, 2017 - APS
We investigate the asymptotic security of one-way continuous variable quantum key
distribution against Gaussian two-mode coherent attacks. The one-way protocol is …

Interactive numerals

H Thimbleby, P Cairns - Royal Society Open Science, 2017 - royalsocietypublishing.org
Although Arabic numerals (like '2016'and '3.14') are ubiquitous, we show that in interactive
computer applications they are often misleading and surprisingly unreliable. We introduce …
