QPC Coherent Architecture

Quantum Polycontextural Computing runs as a coherent architectural circuit family on the QPU: multi-contexture desks, structured bridges, and architecture metrics measured from quantum counts — a different class of quantum computation from hybrid multi-circuit optimization sampling stacks.

Architecture-level contrast

This is a comparison at the quantum computation architecture level — how the machine is used — illustrated with a concrete industry example and a concrete QPC desk.

  • Metric: Marrakesh C2 raw gap 0.185 · retention 0.749 · separable 0.184.

Fourier LCU / QAOA-style multi-circuit sampling

  • Paper: Carrera Vazquez, Egger, Woerner — Efficient Fourier-Based Linear Combination of Unitaries and Applications in Quantum Optimization.
  • arXiv: arxiv.org/abs/2605.18985 (PDF: 2605.18985).
  • Method: Fourier-based LCU decomposes hard unitaries into simpler circuits; classical recombination / scoring; QAOA-class optimization sampling.
  • Hardware figure: 106-node problem graph on IBM heavy-hex (5×3 + SWAP layers); green = best found sampled solution.
  • Class: hybrid multi-circuit optimization stack — different architecture product from QPC desks.

Citation names a published IBM Research path as the hybrid-sampling archetype. QPC does not claim a higher densest-k / graph cost on that instance; the contrast is architecture class and metric.

Why this sells on the QPC side

Positioning line: QPC delivers coherent polycontextural architecture on real quantum processors — structured desks, architecture metrics, IBM-ready resilience — the architecture-level counterpart to hybrid sampling stacks.
