Hybrid Quantum-Classical Architecture Concept

Status: Proof of Concept

This specification outlines a conceptual architecture for hybrid quantum-classical computing. It contains no proprietary source code, operational infrastructure, or production binaries.

Architectural Objectives

1. Continuous Feature Projection: Map continuous classical data \(x \in \mathbb{R}^d\) into the periodic parameter space of an \(n\)-qubit Hilbert space \(\mathcal{H} = \mathbb{C}^{2^n}\).
2. Heterogeneous Device Bridging: Coordinate asynchronous memory transfers between classical linear algebra accelerators and quantum statevector evolution engines.
3. Analytic Differentiation: Propagate loss gradients across quantum-classical boundaries using exact analytic formulation.
