Device-independent quantum key distribution with random key basis

Nature 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.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Quantum Key Distribution [PDF]

, 2010
In this chapter a complete QKD protocol is presented, starting from the transmission via the quantum channel up to the communication over the public channel. The protocol described here is the BB84 protocol, named after Bennett and Brassard [5]. There are other protocols like the B92 protocol [3], the six-state protocol [8], the SARG protocol [19] and ...

Quantum key distribution using unknown quantum states

AIP 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.

Numerical finite-key analysis of quantum key distribution

npj Quantum Information, 2020
Quantum key distribution (QKD) allows for secure communications safe against attacks by quantum computers. QKD protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments,

Quantum Key Distribution Over Double-Layer Quantum Satellite Networks

IEEE Access, 2020
Quantum key distribution (QKD) has attracted much attention on secure communications across global networks. QKD over satellite networks can overcome the limitations of terrestrial optical networks, such as large attenuation over long distance fiber ...

Progress in satellite quantum key distribution

, 2017
Quantum key distribution (QKD) is a family of protocols for growing a private encryption key between two parties. Despite much progress, all ground-based QKD approaches have a distance limit due to atmospheric losses or in-fibre attenuation.
