A Native Toffoli Gate

And Why It’s A Big Deal The Advanced Quantum Testbed (AQT) of the United States Department of Energy (DOE) has announced a native Toffoli gate. Okay, so what the heck does that mean? Let’s start from the beginning…. A Toffoli gate, aka CCNOT, aka controlled-controlled-NOT…

Choose Your Own Quantum Adventure

A Personalized Career Guide When I shared my first book, “Dungeons & Qubits: an Adventurer’s Tale Beyond the Quantum Computing Tutorials,” on June 6, 2021, I simply uploaded the PDF to Google Drive and posted the link everywhere I could. I didn’t anticipate any degree of popularity, so I gave zero thought to analytics…

What I Learned From Fire Opal…

…is that I gotta have more Fire Opal…. I recently wrote an article titled, “Q-CTRL’s Fire Opal is Awesome.” The TL;DR of it is that I gave the Fire Opal team deep circuits that produce sheer noise on NISQ devices and they returned to me practical results from NISQ devices. How’d they do it? They reveal a few…

QC Startup Turing: the Full Picture

One interview. Three unique articles. I recently interviewed Prof. Seth Lloyd and Dr. Michele Reilly about their quantum computing startup, Turing. The responses would have made for one really long article, so I divided the content into three articles and submitted them to three different publications. Each article, intentionally, has unique content and a unique…

Review: Black Opal’s “Programming” by Q-CTRL

A Gentle Transition From Dragging to Coding This 9th module of Black Opal’s quantum computing tutorials is where the rubber meets the road. This is where you put your nose to the grindstone. And, this is where you wonder why I’m writing every idiom in the English language. I don’t have an answer for that. …

Review: Black Opal’s “Control” by Q-CTRL

You’ve never read a tutorial like it. So many tutorials are redundant, repeated, and repurposed rehashings of earlier retellings of earlier rip-offs of earlier remakes of the earliest quantum computing tutorials. It’s almost as if Hollywood is producing these things. …

Review: Black Opal “Speedup” by Q-CTRL

The First of Black Opal’s Advanced Quantum Computing Tutorials Black Opal’s new “Speedup” module is not what I thought it would be; it’s more. I thought it would be about complexity theory, and it is, but that’s just the first topic of this module. …

“Goodbye, Quantum World!”

It was fun while it lasted. I hereby retire young from the field of “quantum.” I’ve accomplished everything I set out to do and more, and it’ll be years before quantum computers will be mature enough to do much more with them. …
