qVAULT Opens Early Access for Post-Quantum Self-Custody on Hyperliquid

qVAULT launches early access for post-quantum cryptography self-custody on Hyperliquid, using NIST-approved Falcon lattice-based signatures to protect assets against harvest-now-decrypt-later attacks that threaten current ECDSA public keys. The platform enables users to migrate HYPE tokens from traditional elliptic curve cryptography to quantum-resistant security in three steps without requiring advanced technical expertise.

Can Quantum Federated Learning Withstand Circuit-Level Backdoors?

Researchers identify critical vulnerabilities in Quantum Federated Learning (QFL) systems through a novel Circuit-Level Backdoor Threat (CULT) model that demonstrates how malicious clients can exploit quantum mechanisms to degrade model accuracy. Existing defense mechanisms fail to fully prevent attacks, with accuracy dropping up to 50% even against popular mitigation strategies like Krum and FLGuardian.
