EQPU – 0DSTL Architecture: Deterministic Quantum-Analog Computing Framework (v7)

Update Notice – Version 7 last LTspice Analog Core full update In this V7 update, the neo field (active bit width) is introduced and fully implemented. neo defines the number of digitally interpretable output channels (1…64 in the examples), while the analog core itself remains continuous and unbounded. The Bbit-layer uses neo to restrict interpretation strictly to the active word size and to prevent cross-bit leakage, enabling variable-width operation without restructuring the circuit. In V7, explicit operator definitions such as XOR-like, ADD-like, LSHIFT, RSHIFT, and others are added. These operator modes are selected through the modulation voltage V(mod). The analog computation remains identical for all operators; only the digital interpretation mapping changes. Thus, classical multi-stage digital cascades (e.g., ALU → register → ALU) are replaced by a single analog emergent computation, followed by a lightweight digital interpretation step that applies the operator transformation to the projected bits. For those who need it even faster or with less energy, the interpretation can also be performed analogously, and only the final state digitized. Quantum-compatible interpretation With these additions, the 0DSTL architecture remains fully compatible with a qubit-like or qudit-like implementation. The analog core, which classically performs computation through continuous voltage interference, corresponds directly to the continuous amplitude and phase state space of a qubit or qudit. The control variable V(mod) functions as a unitary transformation selector on this state space. The field neo defines the dimensionality of the active Hilbert subspace used for interpretation (e.g., 2, 4, 8, … active basis states). The digital interpretation stage (Bbit layer) corresponds to the quantum measurement process, converting the continuous state into discrete outputs according to the selected operator mapping. This makes the analog 0DSTL core replaceable 1:1 by a qubit-like core without altering: the system logic, the operational workflow, the mapping mechanisms, or the operator definitions. Only the physical implementation of the continuous state changes; the architecture does not. Bit width and physical limits The range 1 to 64 bits in the examples is not an architectural limitation. The true maximum bit width depends solely on the physical information resolution of the analog emergent state. The maximum representable digital width is therefore determined by the information-theoretic limit: max_bits = log2( signal_span / noise_floor ) This applies equally to: the analog classical implementation, and any qubit/qudit implementation (where “signal span” corresponds to the amplitude-space separability). Thus, the practical bit width is limited only by physical resolution, not by the architecture itself. 0DSTL implements a real physical superposition — not as multiple discrete states existing simultaneously, but as a single continuous state that can be digitally interpreted in different ways. The analog core therefore realizes the mathematical structure of superposition without the limitations of quantum-mechanical qubits. E.g 1 Input = Multiple Outputs. The analog core behaves like a universal continuous state element. It mirrors the mathematical properties of qubit-like state spaces (continuous amplitudes, reversible operators) while simultaneously functioning as a neuromorphic neuron (weighted summation, modulatory control, thresholded projections). A single physical mechanism unifies both models.
