Twin-field quantum key distribution with passive-decoy state
Twin-Field quantum key distribution (TF-QKD) and its variants, e.g. phase-maching QKD, sending-or-not-sending QKD, and no phase post-selection TFQKD promise high key rates at long distance to beat the rate distance limit without a repeater.

A Survey of Machine Learning Assisted Continuous-Variable Quantum Key Distribution
Continuous-variable quantum key distribution (CV-QKD) shows potential for the rapid development of an information-theoretic secure global communication network; however, the complexities of CV-QKD implementation remain a restrictive factor.

معرفی یک نسخه حالت فریب از پروتکل چند بعدی قطبش-فاز و تشریح نحوه پیادهسازی و اجرای آن [PDF]
یک 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.

Numerical method for finite-size security analysis of quantum key distribution
Quantum key distribution (QKD) enables secure information exchange with untrusted quantum links between remote communication parties. A central task in the studies of QKD protocols is security analysis, which aims at deriving the length of the final key ...

Security Analysis of Sending or Not-Sending Twin-Field Quantum Key Distribution with Weak Randomness
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.

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...
