Abstract:

Quantum Computation & Artificial Intelligence have been
progressing from mere theoretical promises to experimental realities, and the
cryptographic primitives, more than anything else, must thereby adapt to the
noisy and limited-scaled capabilities of current quantum processors and over
that mitigate the increasing gap between the expansion and scaling of AI
Infrastructure, and the mostly underdeveloped security aspects of the said
autonomous ecosystem. In this work, or odyssey of sorts, is introduced
MARK-B.L.U. (Base Layer Unification); a novel quantum hash function
architecture constructed using parameterized quantum circuits explicitly
designed for Secure Agent Identity and Verifiable Autonomous AI outputs.
MARK B.L.U. serves as both a research framework and a defense model,
providing not only an understanding, but also a practical and interpretable
blueprint for investigating entropy generation, randomness extraction, and
quantum-based hash properties. Unlike classical hash functions or existing
quantum proposals that assume fault-tolerant architectures, the MARK-B.L.U.
operates within the practical limitations of current hardware, balancing circuit
depth, gate fidelity, and entropy spread. Presented here is also a comprehensive
evaluation of the proposed architecture's behavior under multiple
classical-to-quantum input encodings, simulated randomness profile through
entropy distribution, and sensitivity analysis through collision resistance,
avalanche effect, and bit independence tests. Furthermore, the research
positions this architectural framework within the broader landscape of quantum
cryptography by contrasting it against classical and quantum hash proposals
identifying the niche it fills — that of a modular, scalable, and pedagogically
rich hash function for autonomous infrastructure, which is operable "today".
Moreover, by providing reproducible code, empirical validation, and
educational scaffolding, this research work aims to catalyze both further inquiry
and implementation of quantum hashing on real quantum hardware, while
offering a stepping stone towards future fault-tolerant cryptographic primitives.
