Security Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution with Weak Randomness
Entropy, 2022 Sending-or-not sending twin-field quantum key distribution (SNS TF-QKD) has the advantage of tolerating large amounts of misalignment errors, and its key rate can exceed the linear bound of repeaterless quantum key distribution.

Analysis of a commercial QKD System with different Single Photon Detectors
, 2022 reservedQuantum Key Distribution (QKD) è un metodo sicuro utilizzato per lo scambio di chiavi crittografiche tra due dispositivi. Sfrutta i principi della meccanica quantistica come il principio di indeterminazione e il collasso della funzione d'onda ...

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks
Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Thinking and feeling about novelty: How cognition and emotion shape investment in novel ideas
Strategic Management Journal, Volume 47, Issue 8, Page 2208-2234, August 2026.Abstract While prior research on the strategic framing of innovation highlights the cognitive mechanisms underlying novelty evaluation, we know little about the corresponding emotional mechanisms. Drawing on appraisal theory, construal level theory, and the literature on emotions, we theorize two distinct appraisal‐emotion pathways through which the ...

High-speed integrated QKD system [PDF]
, 2022 Quantum key distribution (QKD) is nowadays a well established method for generating secret keys at a distance in an information-theoretic secure way, as the secrecy of QKD relies on the laws of quantum physics and not computational complexity.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
InfoMat, Volume 8, Issue 7, July 2026.A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

معرفی یک نسخه حالت فریب از پروتکل چند بعدی قطبش-فاز و تشریح نحوه پیادهسازی و اجرای آن [PDF]
پدافند الکترونیکی و سایبرییک مشکل همیشگی در پیادهسازی تجربی سامانههای توزیع کلید کوانتومی (QKD)، تولید تکفوتون است. روند متداولی که برای تولید تکفوتونها به کار میرود، استفاده از پالسهای لیزری تضعیف شده است. در این صورت، شمار فوتونها از یک توزیع پواسونی پیروی میکند.
