Workshop Description
For C-suite and portfolio management leads. Covers the limits of classical Markowitz and mean-variance models, quantum algorithms for large-scale optimisation, benchmark-specific performance comparisons, adoption frameworks, and independent guidance on quantum optimisation vendors.
Classical mean-variance optimisation hits a computational wall as asset universes grow beyond a few hundred instruments with real-world constraints (cardinality limits, sector caps, turnover bounds, transaction costs). The problem is NP-hard in its general form. Quantum optimisation algorithms, specifically QAOA and variational methods, offer a different approach: encoding portfolio constraints as QUBO (Quadratic Unconstrained Binary Optimisation) problems and solving them on quantum hardware or quantum-inspired classical solvers. Published benchmarks from JPMorgan, Goldman Sachs, and academic groups show that for portfolios of 20 to 80 assets with realistic constraints, current NISQ hardware can find solutions competitive with classical solvers. The practical question is not whether quantum advantage exists in theory, but at what asset universe size and constraint complexity the crossover occurs for your specific portfolio construction workflow. This workshop maps that boundary, works through the formulation process, and evaluates the vendor landscape with independence.
What participants cover
- Classical Markowitz limitations: why mean-variance optimisation becomes intractable with real-world cardinality and turnover constraints
- QAOA and VQE for portfolio construction: how quantum algorithms encode and solve constrained asset allocation problems
- QUBO formulations: translating financial constraints (sector limits, position bounds, tracking error) into quantum-native problem representations
- Benchmark evidence: published results from JPMorgan, Goldman Sachs, and academic groups comparing quantum versus classical solvers at different asset universe sizes
- Hardware limits: the NISQ performance ceiling (20-80 assets with noise mitigation) and the fault-tolerant frontier for institutional-scale portfolios
- Vendor assessment: independent comparison of IBM, IonQ, D-Wave, Quantinuum, Multiverse Computing, and quantum-inspired classical alternatives
