We explore words, theories, the classical as our access to the quantum, and information as the key to the structure of space-time and the universe. “We speak not because speech is perfect, but because silence is impossible” (Augustine, paraphrased). Logos philosophy and information as creation.

Friday Mar 28, 2025

The scale of the challenge of factoring huge composite numbers, Shor’s algorithm, and why we are not going to crack RSA encryption any time soon using quantum computing.

Friday Mar 28, 2025

How we encode numbers, process the results, and decode the answers using inverse quantum Fourier transforms to obtain a usable answer.

Friday Mar 28, 2025

Some details about how quantum Fourier transforms work.

Friday Mar 28, 2025

Starting to understand quantum Fourier transforms - the basic idea.

Thursday Mar 20, 2025

Some of the practical challenges that make it so difficult to run code on real quantum computers even when the same code runs perfectly well on a simulator.

Thursday Mar 20, 2025

How does a Grover oracle test whether a solution is a solution without measuring the state vector it is assessing and so destroying it? Invisible operators and hidden manipulation. Uncomputing as a road from the depths of the enigma back to somewhere closer to where we can obtain the answer.

Thursday Mar 20, 2025

In what respects the quantum world and our access to it is a fitting metaphor for the human brain and consciousness as what we can directly know about it.

Thursday Mar 20, 2025

Quantum multiplication as a challenge. Why it can work and why it is difficult.

Thursday Mar 20, 2025

Quantum computing teaches and forces us to think differently because it is impossible to understand it in terms of classical physics. Superposition, entanglement, oracles, diffusers, invisible answers and impenetrable state vectors all combine to present us with an entirely new conceptual world that unmakes sense of the older one.
