The DiVincenzo Criteria: Blueprint for Building a Quantum Computer
Quantum computing promises to revolutionize fields from cybersecurity to drug discovery, but building a functional quantum computer is an immense technical challenge. In the late 1990s, physicist David DiVincenzo outlined a set of conditions - now known as DiVincenzo’s criteria - that any viable quantum computing architecture must satisfy. These seven criteria serve as a checklist and roadmap for engineers and investors alike, defining what…

The Skill Stack a CISO Needs for Crypto‑Agility and Quantum Readiness
The path to quantum readiness is navigable with the right combination of skills, planning, and proactive execution. By leveraging existing strengths - the people and processes you already have - an enterprise can evolve its cryptographic foundations without needing a phD in quantum physics on staff. In fact, quantum-proofing your organization is less about radical new technology and more about disciplined security management: inventory your…

Quantum Technology Use Cases in Energy & Utilities
Quantum technologies matter for energy because many challenges in this sector involve combinatorial optimization and molecular simulation at scales classical computers cannot handle. For example, routing power through a grid with thousands of control decisions or modeling the chemistry inside a battery are tasks that overwhelm today’s fastest supercomputers. Quantum computers leverage phenomena like superposition and entanglement to examine a vast number of configurations simultaneously,…

Quantum Baloney Detection Toolkit
Quantum physics is famously weird and fascinating. Its principles (like superposition and entanglement) defy everyday intuition, which gives quantum technology an almost magical aura. Unfortunately, that same mystique attracts a lot of baloney. From overhyped press releases to outright scams and pseudoscience, “quantum flapdoodle” - as Nobel laureate Murray Gell-Mann dubbed it - is rampant. In recent years, a perfect storm of factors (AI hype,…

Fidelity in Quantum Computing
Fidelity in quantum computing measures the accuracy of quantum operations, including how effectively a quantum computer can perform calculations without errors. In quantum systems, noise and decoherence can degrade the coherence of quantum states, leading to errors and reduced computational accuracy. Errors are not just common; they're expected. Quantum states are delicate, easily disturbed by external factors like temperature fluctuations, electromagnetic fields, and even stray…
