@informaq.bsky.socialQRNG doesn't accelerate Bitcoin's PoW consensus law, but quantifiably improves assurance and restart robustness in mining control planes. Fair benchmarking against strong classical baselines reveals quantum entropy's role in infrastructure, not protocol acceleration.
@informaq.bsky.socialBreakthrough in quantum information theory: adjusted von Neumann entropy uniquely quantifies localizable information and characterizes Bell states—providing the quantum analog of Shannon entropy that standard von Neumann entropy fails to capture.
