Quantum Computing Fundamentals
Qubits, superposition, entanglement, and quantum gates. The foundational principles that distinguish quantum computation from classical computing and where the performance differences arise.
Quantum Technologies
Quantum Computing
Expert lectures on quantum computing principles, hardware, algorithms, and real-world applications. From foundational concepts to deployment considerations for engineers, researchers, and business leaders.
What the Lectures Cover
Each lecture runs approximately 20 minutes. Delivered by researchers, engineers, and practitioners with hands-on experience building and deploying quantum computing systems. Recordings available in the member archive alongside all other quantum subject areas.
Quantum Algorithms
Shor's, Grover's, and other quantum algorithms with practical relevance. What they can do, what hardware they require, and their implications for cryptography and optimisation problems.
Hardware Architectures
Superconducting qubits, trapped ions, photonic systems, and neutral atom platforms. How the different physical implementations compare on qubit count, error rates, coherence time, and connectivity.
Error Correction
Quantum error correction: why it is necessary, how surface codes and other approaches work, and the overhead it imposes on logical qubit counts. The path from today's noisy devices to fault-tolerant quantum computers.
Quantum Cloud Services
Access to quantum hardware through cloud platforms. How to evaluate available systems, write and run quantum circuits, and what practical results are achievable in current NISQ-era devices.
Business Use Cases
Optimisation in logistics and supply chain, financial modelling, drug discovery, and energy reduction. How organisations are identifying where quantum computation adds genuine value today versus on a longer timeline.

Why Quantum Computing Matters for Security
Quantum computing is relevant to security professionals for two distinct reasons. The first is the threat it poses to current cryptographic infrastructure. Shor's algorithm, running on a sufficiently large fault-tolerant quantum computer, can factor large integers and solve discrete logarithm problems efficiently. RSA, ECC, and Diffie-Hellman are all vulnerable. The QSECDEF lecture series addresses the current state of quantum hardware, timelines, and what a cryptographically relevant quantum computer actually requires.
The second reason is the operational opportunity. Quantum computing offers genuine advantages in optimisation, simulation, and certain search problems. For organisations in logistics, finance, defence procurement, and energy management, understanding where quantum computation is applicable, and where it is not, is a strategic question.
QSECDEF does not advocate for any specific hardware vendor or quantum cloud provider. The lectures present a range of approaches and let members form their own assessment based on technical evidence and independent analysis.
