Cybersecurity Driven Quantum Digital Twin for Proactive Threat Reversal in Open RAN

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.
This paper presents a novel cybersecurity‐driven quantum digital twin (CQDT) architecture for proactive defence in 6G Open RAN. By integrating quantum observables and reinforcement learning, the framework maintains high fidelity and suppresses entropy under adversarial CPTP noise. CQDT achieves real‐time adaptation with sub‐20 ms latency, meeting URLLC

Liquidity and Price Informativeness of Options: Evidence From Extended Trading Hours

Journal of Futures Markets, Volume 45, Issue 11, Page 2013-2033, November 2025.
ABSTRACT This paper explores the trading dynamics of the options market during extended trading hours (ETHs). During ETH, the options market is characterized by low liquidity and decreased trading activities, yet there is an increased likelihood of informed trading. The introduction of ETH improves overall market liquidity on the following trading day,
