NuQKD: A Modular Quantum Key Distribution Simulation Framework for Engineering Applications

open access: yesAdvanced Physics Research
An experimental Quantum Key Distribution (QKD) implementation requires advanced costly hardware, unavailable in most research environments, making protocol testing and performance evaluation complicated.

Asymmetric twin-field quantum key distribution

open access: yesNew Journal of Physics, 2019
Twin-Field (TF) quantum key distribution (QKD) is a major candidate to be the new benchmark for far-distance QKD implementations, since its secret key rate can overcome the repeaterless bound by means of a simple interferometric measurement.

Device-independent quantum key distribution with random key basis

open access: yesNature Communications, 2021
Device-independent quantum key distribution aims at the ultimate quantum-based unconditional security, but current protocols’ rates are quite far from anything practical.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Passive Decoy-State Quantum Key Distribution with Coherent Light

open access: yesEntropy, 2015
Signal state preparation in quantum key distribution schemes can be realized using either an active or a passive source. Passive sources might be valuable in some scenarios; for instance, in those experimental setups operating at high transmission rates,

Analysis of the gain distribution across the active region of InGaAs-InAlGaAs multiple quantum well lasers [PDF]

open access: yes, 2005
Spectral gain measurements for two InGaAs-InAlGaAs multiple width quantum well structures, with inverse-configured active regions, have been presented. One structure consisted of wide quantum wells near the p-side and narrow quantum wells near the n-side

Daylight entanglement-based quantum key distribution with a quantum dot source

open access: yes, 2023
Entanglement-based quantum key distribution can enable secure communication in trusted node-free networks and over long distances. Although implementations exist both in fiber and in free space, the latter approach is often considered challenging due to ...

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1

open access: yesFEBS Open Bio, EarlyView.
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Quantum key distribution using unknown quantum states

open access: yesAIP Advances
This paper proposes a version of quantum key distribution (QKD) by leveraging unknown quantum states. The measurement made on the unknown quantum states is independent of them.
