All Videos

This section brings together the complete Qubit-Lab video series - from strategy and business implications to finance use cases, technical deep dives, and introductory lessons. The goal is to build both awareness and understanding: how quantum computing works, where it can be applied, and why it matters today.

Each video combines clear explanation with practical demonstrations, often supported by interactive notebooks. You can follow the code, see algorithms in action, and compare quantum approaches with classical methods. Whether you are seeking a high-level perspective or hands-on experience, this collection allows you to explore at your own pace.

QAOA vs. Classical Search: How Quantum Optimization Redirects the Search

QAOA vs. Classical Search: How Quantum Optimization Redirects the Search

Open on YouTube

This video visually compares a classical sequential search with quantum optimization using QAOA. While the classical approach evaluates candidates one by one, QAOA reshapes probabilities across the full solution space to guide the search toward better outcomes. The side-by-side visualization shows how both approaches behave and why quantum optimization differs fundamentally from classical candidate-by-candidate evaluation. The QAOA search shown here is based on a real QAOA run, not a mockup.

QCBM for Quantum Finance: Credit Spread Copulas and Tail Risk

QCBM for Quantum Finance: Credit Spread Copulas and Tail Risk

Open on YouTube

This video presents a structured quantum-finance use case built around copula-based dependence modeling and quantum scenario generation for credit spread tail risk. It explains how empirical credit spread data can be transformed into a joint dependence distribution, why tail regions are difficult to model with sparse classical observations alone, and how a Quantum Circuit Born Machine can be used to learn and sample from that distribution. The discussion covers the intuition behind empirical, Gaussian, and t-copulas, the role of tail dependence in credit risk, and the practical logic of discretizing the joint space before training a quantum generative model. It also positions the workflow in the broader context of Quantum GenAI, highlighting how quantum models may eventually support scenario generation for rare but relevant financial stress events. The goal is to provide a technically grounded but accessible walkthrough of a realistic quantum-finance modeling pipeline.

Open on YouTube

The video builds on the first chemistry introduction and compares the main quantum algorithm choices for estimating molecular ground-state energies in a structured, step-by-step overview. It explains which approaches are relevant on current NISQ hardware, which belong to the fault-tolerant era, and why that distinction matters when assessing realistic timelines for quantum advantage in chemistry. Coverage includes VQE and ADAPT-VQE as near-term hybrid methods, as well as Quantum Phase Estimation with trotterization and with qubitization, including the key tradeoffs in circuit depth, precision, measurement effort, and asymptotic scaling.

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

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.

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.

Quantum is no longer just a research topic - it is becoming a strategic challenge for industries like finance, pharma, and energy. The real question is: how should companies prepare today for a technology that will mature over the next 10-15 years? The key message: it is not about counting qubits. It is about aligning technology evolution with corporate strategy, managing risks early, and building the capability to capture future opportunities.

QAOA Today: How Far Can NISQ Hardware Really Go? (as of April 2026)

Open on YouTube

QAOA is often presented as a promising approach for tackling complex optimization problems. But its real value depends on what today’s hardware can actually support. Current NISQ devices come with strict limitations: noise, limited connectivity, and shallow circuit depths. These are not minor details, they fundamentally shape what QAOA can and cannot achieve in practice. This video takes a grounded look at these constraints and translates them into realistic expectations. Not as a final verdict, but as a clearer picture of where we stand today and what remains out of reach.

What is a Qubit?

Open on YouTube

A qubit is much more than an “extended classical bit. It is the core carrier of quantum behavior - superposition, phase, interference. And in QML, a single qubit can encode a full parameter, making it a powerful resource. Some say you don’t need to understand qubits, just like coders don’t care about voltages in classical chips. I disagree. To truly grasp quantum code, you need at least the general picture of what a qubit really is. This video aims to give you that - not comprehensive, but enough to spark real understanding and curiosity.
