Quantum Initiatives in Finance: Landscape of Methods and Domains (2021–2025)

Open on YouTube

The video maps publicly documented quantum initiatives in finance from 2021 to the end of 2025 in a structured, non-ranking overview. Each initiative is placed in a grid by business domain and by the quantum method or topic used, showing where activity clusters and how it evolves over time. Coverage spans portfolio allocation, credit risk, derivatives pricing, trading, fraud and AML, and cybersecurity. The method and topic columns include quantum annealing, QAOA, quantum Monte Carlo and quantum machine learning, as well as security efforts such as quantum key distribution and post-quantum cryptography migration programs. A legend section provides partner context and references for each entry. This video was created for a finance audience.

Quantum Readiness for Banking Executives: A Practical Playbook

Quantum Readiness for Banking Executives: A Practical Playbook

Open on YouTube

The video presents quantum readiness for banks as a practical capability build, independent of betting on a specific hardware timeline. It starts by separating what a bank can control today from what it cannot, then lays out a staged playbook from initial enablement and use case triage to baseline-first benchmarking, vendor assessment, and controlled pilots. Along the way, it highlights the minimum evidence artifacts a leadership team should expect, including a simple executive dashboard and reusable templates to keep efforts measurable and avoid hype. It concludes with a pragmatic 12 to 24 month roadmap that banks can start this quarter. This video was created for a banking audience.

QAOA Masterclass for Finance: From QUBO to Circuits, Mixers, Constraints, and Credible Reporting

QAOA Masterclass for Finance: From QUBO to Circuits, Mixers, Constraints, and Credible Reporting

Open on YouTube

This QAOA masterclass is a practical, end to end deep dive into constrained optimization with quantum circuits. A quick word of warning: we go all the way down to the low level, including unitaries, gate mappings, and mixer design details. The session starts from problem formulation and shows how to translate real objectives and constraints into QUBO and Ising models, then builds the corresponding cost unitary and maps it to gates. It then focuses on mixer choices, including why the standard X mixer can fail for constrained problems and how constraint-aware mixers can improve feasibility and sampling quality. We close with parameter optimization patterns, common pitfalls, and what to report so results are credible, such as best feasible samples, feasibility rates, and robustness across seeds. This session was created for finance-style optimization use cases.

Quantum Algorithms in Finance: The “Inner Life” of a Qubit, QAOA + QML/VQC, Objectives 2026
FINANCE#13
Released 24 Jan 2026

Quantum Algorithms in Finance: The “Inner Life” of a Qubit, QAOA + QML/VQC, Objectives 2026

Open on YouTube

The talk opens with a simulator-based view of a qubit’s dual life before and after measurement, building intuition for quantum behavior. It then introduces key quantum algorithms, including QAOA and Quantum Machine Learning via Variational Quantum Circuits (VQC), and explains how these approaches are used in practice. The presentation concludes with an outlook on a phased approach to onboarding quantum computing in a financial institution, including concrete objectives for 2026. This session was delivered for a bank.

QML reality check: classical vs quantum

QML reality check: classical vs quantum

Open on YouTube

Discover how Quantum Machine Learning performs in a real finance scenario - we test a hybrid quantum-classical model on S&P 500 market regime prediction and benchmark it against a strong classical baseline. You will see the full experiment end-to-end: engineered features, 4-class regime labels, reproducible runs over many seeds, and a proper statistical test using confidence intervals. This is the same rigorous approach used in industry pilots today. A clear look at whether QML delivers real value beyond decoration.

Q-Day and Post-Quantum Cryptography (PQC)

Q-Day and Post-Quantum Cryptography (PQC)

Open on YouTube

Have a look and see why the UK and EU issued regulatory guidance on the PQC in summer 2025. This video is not really about quantum computing and quantum algorithms in finance, but about the impact of quantum computing on current and future cryptography. A lot of half-baked information is going around, so I decided to make a video that explains modern cryptography from scratch - as simple as possible, but not simpler, as usual in my videos.
