This thesis introduces the SN-112A framework—a deterministic quantum-native methodology for planar linkage synthesis that concurrently optimizes topology, geometry, and trajectory.
By converting binary link-presence variables into QUBO and Ising Hamiltonians, the approach harnesses quantum annealing and gate-based algorithms (QAOA/VQE) to discover globally optimal mechanisms, surpassing classical heuristics.
Validated through polycentric prosthetic knee design, the framework yields 30% lighter, 2× faster-to-design linkages. Future prospects include quantum-generated mechanical patents, a Design-as-a-Service API, and ventures in defense, space, and biomedical sectors.

QUBO: E(x) = Σᵢ aᵢxᵢ + Σᵢ<ⱼ bᵢⱼ xᵢxⱼ xᵢ ∈ {0,1}
Ising: H = Σᵢ hᵢσᵢᶻ + Σᵢ<ⱼ Jᵢⱼσᵢᶻσⱼᶻ sᵢ ∈ {-1,+1}
Transform: xᵢ = (1 + sᵢ)/2
hᵢ = aᵢ/2 + Σⱼ bᵢⱼ/4
Jᵢⱼ = bᵢⱼ/4Multi-backend quantum orchestration spanning annealing, QAOA, and VQE across 600+ qubit systems.
The Ising Hamiltonian is directly embedded on D-Wave Advantage (5,000+ qubits). The system evolves from a transverse-field ground state to the problem Hamiltonian's ground state, reading out the optimal topology configuration.
Access via D-Wave Leap cloud platform with Ocean SDK. Ideal for large-scale QUBO problems (>5,000 binary variables).
H(s) = (1-s)·H_init + s·H_problem
H_init = -Γ Σᵢ σᵢˣ (transverse field)
H_problem = Σᵢ hᵢσᵢᶻ + Σᵢ<ⱼ Jᵢⱼσᵢᶻσⱼᶻ
s: 0→1 over anneal time τ (typically 20–2000μs)QAOA applies alternating problem and mixer unitaries for p layers, optimizing variational parameters to minimize ⟨H⟩. Implemented via Qiskit on IBM Quantum (600+ qubits). VQE uses a parameterized ansatz circuit to estimate ⟨H⟩ with classical optimization. Best for fine-tuning topology on IonQ Forte or Quantinuum H-Series.
|ψ₀⟩ = H⊗ⁿ|0⟩ (uniform superposition)
For k = 1 to p:
U(γₖ) = exp(-iγₖH) ← problem unitary
U(βₖ) = exp(-iβₖΣσˣ) ← mixer unitary
⟨ψ(γ,β)|H|ψ(γ,β)⟩ → minimized classicallyClassical Gurobi branch-and-bound provides a warm start, solving the convex relaxation of the MICP. The quantum solver then refines over binary feasibility. This hybrid approach reduces quantum circuit depth by ~60% while maintaining global optimality guarantees. Orchestrated via AWS Braket hybrid jobs or Azure Quantum workspace.
