ABSTRACT: This paper presents STOC-QComp, a device-level engineering framework for a bounded-capacity quantum processor incorporating thermodynamic control, a mechanically tunable Casimir structure, and deployment-specific environmental engineering. The work extends the STOC-QC control framework [1] [2] by introducing the Casimir plate separation d as an experimentally accessible mechanical degree of freedom. Rather than assuming direct coupling between the static Casimir spectrum and the qubit transition, the revised device model treats the Casimir structure as a mechanically tunable boundary condition whose displacement may modify the electromagnetic cavity frequency, qubit-cavity coupling, and associated dissipation rates. The proposed 40 - 400 nm operating range is therefore treated as a design hypothesis requiring finite-conductivity Casimir modelling, electromagnetic simulation, mechanical stability analysis, and experimental validation. The paper specifies a reference superconducting-transmon architecture for the millikelvin deployment tiers, a separate 4 K control and characterisation configuration for the personal tier, manufacturing and yield assumptions with explicit evidence-class labels, environmental-noise budgets with quantitative transfer functions, and four falsifiable device-level tests with a full statistical analysis plan. Manufacturing costs and yields are explicitly classified as vendor quotations, engineering estimates, or experimental targets. The proposed 200 - 1000 qubit bounded-capacity regime is treated as a testable hypothesis motivated by Palmer’s bounded-Hilbert-space proposal [3] rather than an established physical limit. The result is a falsifiable device framework and experimental roadmap rather than a claim of completed commercial deployment.
