Framework

Hardware selection and infrastructure requirements?

Qubit requirement and provider selection?

1000-5000 logical qubits needed for meaningful problem class

NISQ era current hardware: 100-1000 physical qubits, 99% fidelity

Quantum error correction overhead: 1000:1 ratio (1M physical → 1K logical)

Classical-quantum hybrid architecture and access model?

Cloud-based access (IBM Quantum, Google Quantum, Azure Quantum) vs on-premise

Hybrid architecture cost: $100-500K/year cloud + $2-5M development

Integration: classical preprocessing + quantum circuit + post-processing

Algorithm design and quantum advantage validation?

Quantum algorithm selection and feasibility?

QAOA (Quantum Approximate Optimization) best for portfolio problems

Quantum advantage threshold: 1000x-10000x speedup possible for this problem

Proof-of-concept timeline: 6-12 months with simulators + real hardware

Quantum advantage validation and benchmarking?

Benchmark against classical heuristics: simulated annealing, genetic algorithms

Error rate tolerance: 0.1% logical error per operation acceptable for portfolio

Production readiness: 24-36 month path from PoC to deployment

Team capability and enterprise economics?

Team skill development and hiring?

Skills needed: quantum physics, algorithms, finance domain expertise

Team size: 8-15 engineers (PhDs in physics/CS preferable)

Learning curve: 12-18 months to build proficiency on quantum hardware

ROI and business case?

Annual quantum computing cost: $2.5-5M (infrastructure + team)

Expected benefit: 8-hour → 1-hour optimization (87.5% time savings)

Break-even ROI: 4-6 years (critical gate for capital allocation)
