QHDALabs
Independent research laboratory

Quantum information, measured honestly.

QHDALabs investigates measurement-driven quantum dynamics, cryptography from quantum trajectories, and applied AI systems. Methods, code, and failure modes are published openly — negative results included.

QHDA-QM-01 qmnet — Measurement-Fueled Conditional Bridges Graph-state echo experiments in Qiskit. Conditional CZ bridges driven by mid-circuit measurement; quantifying which bridge topologies disrupt echo return. Home of the RQTE paper — encryption from quantum measurement trajectories. Active QHDA-AI-02 RTANA — Relational Temporal Awareness in Neural Architectures Can a neural system have an internal relational clock? Qiskit event generation coupled to recurrent networks: do distinct measurement histories produce meaningfully distinct hidden-state representations? Active QHDA-CO-03 XSIG — Cross-Cycle Structural Information Geometry Quantum-algorithmic search for non-random structural signatures in cosmological data, framed against Conformal Cyclic Cosmology. Pipeline under iteration; failure modes and open issues tracked publicly. In development QHDA-CO-04 Universe — Precision Cosmology & Emergent Systems Research initiative for precision cosmology and emergent systems; observational-data groundwork supporting the XSIG program. Exploratory QHDA-TH-05 Coherence Bridge Coherence-layer abstraction between relational quantum models and executable substrates — the connective tissue between theory repositories and runnable code. Exploratory QHDA-TH-06 Multiverse Theory Theoretical notes and TeX manuscripts on multiverse-adjacent frameworks; speculative groundwork, clearly separated from the experimental programs above. Exploratory QHDA-SN-07 Axon — the Science Nervous System Relational infrastructure over the scientific literature: the relation is the unit, and verification comes before discovery. Swanson-style ABC bridges with explicit nulls — including a pre-registered held-out test that failed, documented in the open. Built on qhda-core. Active QHDA-LIB-08 qhda-core — Shared Quantum-Relational Mechanisms Four mechanisms distilled from qmnet, RTANA and XSIG — conditional CZ bridges, the Page–Wootters clock, the relational-state accumulator and the emergent clock — packaged as a reusable two-layer library: quantum (Qiskit) and relational (pure numpy).
