I am fortunate to work for a global systems integrator that is leading the way in photonics and quantum computing. The organisation is deeply involved in the development and deployment of Coherent Ising machines and are a driving force behind the Innovative Optical and Wireless Network, known as IOWN. This

Quantum computing is often described as a dramatic departure from classical information processing, yet its foundations lie in the strange and elegant rules of quantum mechanics. The QCGuy article Quantum Mechanics The Basis of Quantum Computing introduces these principles with clarity, explaining how superposition, entanglement and the probabilistic nature of

Just recently, I was at a conference and had a candid chat with one of our banking customers who expressed a major concern: how exposed their financial data is to future quantum attacks. This critical worry instantly turned our conversation to Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and the

The revolution promised by quantum computing is not a solitary endeavour. As researchers and engineers worldwide grapple with the immense challenge of scalability, moving from a handful of functional quantum bits (qubits) to the millions required for genuine "quantum advantage", a powerful concept has emerged: the quantum computing

The cybersecurity landscape is undergoing a fundamental transformation as organisations grapple with an unprecedented threat: the advent of cryptographically relevant quantum computers (CRQCs). Whilst large-scale quantum computers remain years away from commercial viability, the danger they pose is immediate and profound, particularly through "Harvest Now, Decrypt Later" (HNDL)

As quantum computing transitions from laboratory curiosity to commercial reality, network architects face an unprecedented challenge, designing networks capable of handling quantum information. The answer requires reimagining foundational networking principles while confronting formidable implementation hurdles. The Foundation Under Pressure For over forty years, the seven-layer OSI model has provided the

I was recently in the fortunate position of being asked to provide insights for a global banking client regarding the business values of quantum computers but the most important dimension everyone seems to downplay is the threat to cybersecurity. The digital world has relied on cryptographic algorithms to protect our
