EXXOGEN Validates Continuous-Time Quantum Dynamics Model on 108-Qubit Rigetti QPU

BUDAPEST / — EXXOGEN today announced hardware validation results for its continuous-time geometric model, executed on Rigetti's 108-qubit Cepheus-1-108Q superconducting quantum processor. The benchmark examined how quantum entanglement and CHSH inequality violation manifest within the model's internal dynamics.

Key Benchmark Highlights (Rigetti) Entanglement Measurement on QPU: On the Rigetti Cepheus-1-108Q hardware, the mapped gate sequence achieved a measured S-value of 2.404, exceeding the classical limit (S ≤ 2.000).

(QISKIT + PennyLane) Tsirelson Convergence: EXXOGEN's deterministic dynamics yielded a theoretical CHSH parameter of 2.82842712474619, approaching the quantum bound of 2.8284271247461903.

Quantum Benchmarks: 0.9966 quantum teleportation fidelity, 1.0000 (100%) error correction success rate, and a Quantum Volume Heavy Output Probability of 0.8272 (above the 2/3 threshold).

Invariant Conservation Under Noise: Continuous dynamical evaluation confirmed that radius fluctuations (R_A, R_B) and decoherence parameters (|R_A - R_B|) preserve internal geometric invariants (I), driving the Bell correlation curve E(a,b) toward the quantum cosine distribution.

IP-Protected Hardware Execution: Local geometric invariants were mapped to standard single-qubit rotation gate parameters (θ, φ), allowing remote cloud execution on the QPU while EXXOGEN's closed-form equations remain fully protected.

Alongside heuristic or unverified simulation approaches, EXXOGEN connects continuous-time geometric modeling with standard quantum gate execution, protecting its proprietary logic while producing verifiable results on third-party quantum hardware.

The PennyLane simulation was performed as an independent benchmark, building on prior Qiskit validation to evaluate cross-platform behavior across multiple independent SDKs and providers.

The CHSH measurement on Rigetti hardware served as a physical validation of our core mathematical operator. Through this experiment on quantum hardware, we examined how EXXOGEN's continuous-time geometric equations describe physical systems.

Data & Architecture Overview Theoretical CHSH Bound: 2.82842712474619 (EXXOGEN model) vs. 2.8284271247461903 (quantum boundary)

QPU Execution Target: Rigetti Cepheus-1-108Q (108 superconducting qubits)

CHSH Violation Outcome: Measured S = 2.404

EXXOGEN Identifies Terahertz Resonance in Alzheimer's Tau Fibrils — New Avenues for Biophysical Research

First-principles simulations of Tau aggregates (7PX3) reveal distinct energy minima and dynamic THz-frequency vibrations, offering fresh physical insights into neurodegenerative protein structures.

BUDAPEST / — EXXOGEN, a deep-tech molecular simulation provider, today announced new findings from its physical analysis of the Tau amyloid fibril (7PX3), a structure strongly associated with Alzheimer's disease.

Utilizing EXXOGEN's proprietary mathematical model, the system evaluated the physical dynamics of the Tau backbone, identifying structural elasticity and collective vibrational behavior in the terahertz (1.2–1.3 THz) frequency range.

Key Physical Findings: Distinct Energy Minima: The structural backbone shows defined energy minima at 2.25 Å and 3.25 Å. Structural Elasticity: The bound backbone demonstrates a stable spring constant range of 0.3–0.8 N/m. Terahertz Vibrational Peak: Internal atomic vibrations display a sharp collective peak at 1.2–1.3 THz.

Implications for Future Research Understanding the physical and mechanical properties of Tau aggregates opens new avenues for Alzheimer's research. By mapping these specific vibrational frequencies, EXXOGEN's data may provide a foundation for researchers to explore frequency-based diagnostic and therapeutic approaches alongside traditional pharmacology.

"Mapping the physical and thermodynamic behavior of macromolecular structures gives researchers new perspectives to consider," said the Founder of EXXOGEN. "Identifying discrete vibrational frequencies in Tau fibrils provides a physical dataset that can support ongoing research in biophysics and neurodegeneration."
