I love neutral atoms.

And they love me, too. This is a companion article to Russ Fein’s article “Quantum Computing with Neutral Atoms.” This article is the second in a series of articles reviewing the hands-on usage of publicly-available neutral atom products. The featured image above is from QuEra’s 256-qubit “Aquila” neutral atom quantum computer, which I accessed via…

Technical Interview: QuEra

Cloud-Based Neutral Atom Quantum Computing This is a companion article to Russ Fein’s article “Quantum Computing with Neutral Atoms,” which, in all honesty, is much better than this one. This article will be the first, however, in a series of articles reviewing the hands-on usage of publicly-available neutral atom products. Thanks to Dr. Nate Gemelke…

Fun with Beam Splitters

It’s past time to deep dive photonics. It turns out that photonics is no harder than working with any other type of qubit. If you play with the operations enough, you can eventually get a good feel for what they do and how photonics compares to, for example, superconducting quantum computing. …

Dynamic Quantum Circuits, Lesson 8

Is Dynamic OpenQASM 2 possible? Whether you use a Jupyter notebook, the OpenQASM editor, or the drag-and-drop circuit builder, your circuits all end up the same at execution time. So, that got me wondering: since some devices now support dynamic instructions from OpenQASM 3, do they support the equivalent instructions from…

Precision Quantum Phase Estimation

Precisely how precise can we get? In my recent article titled “Quantum Phase Estimation!” I showed how Fire Opal can illuminate useful results from within the noise of a 6-qubit QPE circuit. In response, Jack Krupansky asked how precise we can get. That’s a great question, so let’s find out, shall we? But, first, a brief…

IBM Quantum vs AWS Braket

An Oversimplified Cost Comparison I’ve written many times, including in my book “Dungeons & Qubits: an Adventurer’s Tale Beyond the Quantum Computing Tutorials,” that IBM Quantum has charged me a whopping $0.00 over the years. But, I just started using AWS Braket for a specific project, and it got me wondering what the cost…

Q: What Are the Hardest Algorithms?

A: They’re all easy. Just kidding. Not all quantum algorithms are easy. But, I‘ve been asked what I think are the hardest ones. Additional criteria are that the algorithms should be practical, scalable, and not textbook like Shor’s Factoring Algorithm and Grover’s Algorithm. …

Fire Opal Stands Alone

For best performance, use raw circuits. I was honored to pre-beta Fire Opal, but the downside afterward was that Fire Opal was not yet available outside this pre-beta testing. While waiting for its release, therefore, I put together an ensemble of libraries to try to achieve comparable results. And now that Fire Opal is out and…

Quantum Phase Estimation!

Now witness the true power of Q-CTRL’s Fire Opal. In a recent article titled “Grover’s Algorithm with Fire Opal,” I showed how Fire Opal can take a uniform distribution — sheer noise — and illuminate the correct result. But, that was just a Grover’s circuit, which doesn’t have a reputation for being impractical. So, my thoughts turned to Quantum…
