Quantum Searching in Your Browser

If you’ve made it through the last two posts on quantum computing (QC), then you’ve seen the Quirk simulator, a little of IBM’s web-based offering, and how entanglement and superposition can do strange and possibly wonderful things. However, the superdense encoding I showed you didn’t really feel like a real computer algorithm. This time we will look at Grover’s algorithm which is often incorrectly billed as an “unstructured database search.” In reality, it is an algorithm for making a state — that is a set of qubits — match some desired state without simply setting the state.

By analogy, consider …read more http://pje.fyi/QFS8cp

Key to Soldering: Pace Yourself

When writing my last article, I came upon something I thought had been lost to the seven seas of YouTube: the old-school “Basic Soldering Lesson” series from Pace Worldwide.

This nine-episode-long series is what retaught me to solder, and is a masterpiece, both in content and execution. With an episode titled “Integrated Circuits: T0-5 Type Packages & Other Multi-leaded Components” and a 20-minute video that only focuses on solder and flux, it’s clear from the get-go that these videos mean business. Add that to the fact that the videos are narrated by [Paul Anthony], the local weatherman in the Washington …read more http://pje.fyi/PRM4Vq
