As I am about to complete five years of immersion in quantum computing, this stage of my quantum journey is coming to an end and I need to start preparing for the next stage of my quantum journey. I have no fixed idea what this next stage will be like…

What do you say when someone asks what a quantum computer or quantum computing is? In 30 seconds or a minute or so. These are my two suggested brief answers — elevator pitches — to the twin questions: What is a quantum computer? What is quantum computing? Also included are…

In order to put quantum computing in context, we need to be able to discuss who is trying to do what and how they are going to do it. Personas are the who, use cases are the what, and access patterns are the how. Personas, use cases, and access patterns…

IBM posted an update to its quantum roadmap for achieving large-scale, practical quantum computing back in May (2022). This informal paper gives my thoughts on this update to their previous roadmap. Since IBM issued their roadmap update in May, I’ve had three months to study and digest it in enough…

This informal paper is designed to provide a brief but meaningful introduction to quantum computing — the process and significance of using quantum computers to address compute-intensive application problems, but without getting bogged down in any of the detailed technical jargon. …

Premature commercialization of quantum computing will be counterproductive and lead to unnecessary disenchantment with the long-term potential for quantum computing. At the extreme, this disenchantment could lead to a Quantum Winter in two to three years due to failure to meet excessive expectations. Despite the dramatic progress of quantum computing…

Quantum computing desperately needs to show some realistic results addressing more than toy-like problems within the next two to three years if a Quantum Winter is to be averted. This informal paper proposes a quantum computer with 48 fully-connected near-perfect qubits as an ideal goal for the next two to…

I phrase it as a question, but it does seem unavoidable — that quantum computing requires quantum Fourier transform (QFT) or comparable techniques which rely on fine granularity of phase angles that does not currently exist in near-term quantum computers and is unlikely to ever exist in any real quantum…
