Beyond Signatures: Zero-Knowledge Access Control for the Quantum Blockchain
A new framework, ZK-ACE, leverages zero-knowledge proofs to dramatically reduce on-chain data and enhance the scalability of blockchain systems preparing for the post-quantum era.

![Driven by a shared underlying process [latex]Q_{t}[/latex], an ensemble of response functions gracefully converges toward a random attractor-a pair of antipodal points that subtly shift with the passage of time, demonstrating an inherent, dynamic equilibrium.](https://arxiv.org/html/2603.06187v1/Unknown-10.png)
![The driven spin chain exhibits a phase diagram - detailed in the [latex] Q_0 - \omega_D [/latex] plane - where scar-induced oscillations and Floquet ETH-predicted thermalization compete, transitioning via a modulation of [latex] \omega_D [/latex], and further delineated by lines representing weak and strong Hilbert space fragmentation dependent on sector-specific spin configurations.](https://arxiv.org/html/2603.06111v1/x21.png)

![The comparison of Monte Carlo (MC@NLO) predictions with next-to-leading order (NLO) fixed-order calculations and leading-order approximations-both with and without parton shower effects-demonstrates the process [latex]e^{+}e^{-}\to Z \to e^{+}e^{-} [/latex] at a center-of-mass energy of 365 GeV, highlighting the importance of higher-order corrections and parton shower modeling for accurate theoretical predictions.](https://arxiv.org/html/2603.05585v1/x45.png)
