In Loving Memory of the 2nd IBMQ Tutorials Thanks to Jack Krupansky for suggesting this review. I have historically published reviews only if I’ve been able to identify more “The Good” than “The Bad” and “The Ugly.” That won’t be the case here, but an in-progress LinkedIn poll is showing that honest assessments are in demand, even if…

But, standalone quantum restaurants exist. I recently described IBM Quantum as a food court. With the hardware, the simulators, the portal, and the Qiskit framework, there is nowhere else you can go and find that much variety. A good rule of thumb is that if you have a craving for something, you can probably find…

We put an awful lot of faith in them. At the time I’m writing this, I’ve evaluated 99 quantum computing frameworks, platforms, and utilities. They’re all written with classical computer code. …

It’s the optimal way to go. At the time I’m writing this, I’ve evaluated 99 quantum computing frameworks, platforms, and utilities. One of the most recent additions required a little troubleshooting from the creator(s). Fortunately, it eventually worked. Unfortunately, that’s not always the case. The problem isn’t unique to that particular product. In fact, this problem…

Quantum vs. Classical-Quantum I’ve been reading a June 29, 2023, paper titled, “MNISQ: A Large-Scale Quantum Circuit Dataset for Machine Learning on/for Quantum Computers in the NISQ era,” and it sure does look familiar. I’m thinking that’s probably because I published “784-Dimensional Quantum MNIST” on December 9, 2021. …

Qiskit Circuits on a Photonic Quantum Computer Here’s a nifty library for you legion of happy Qiskiteers out there: Perceval. You’ve run your circuits on IBM backends. Since many of them have contributed to Qiskit’s open source code, you may have even run your circuits on IBM’s competitors’ backends. Now you can convert your Qiskit circuits to…

How can we know for sure via the cloud? My recent article titled, “How Do You Verify Entanglement?,” left a question unanswered: “How can we cloud users know for sure that we’re actually accessing real quantum computers?” I had no answer for it, so at the time of publication I reached out to some connections at some major providers…

The Tutorial Answer No Longer Suffices I was asked an interesting question the other day: how do we know if we’re really entangling qubits? I thought back to the first experiment I ever ran, and I almost gave the tutorial answer. But, three things stopped me: The questioner wasn’t a novice and couldn’t have thought I…

It was more insightful than I expected it to be. The IBM Quantum Spring Challenge was insightful, unfortunately not due to anything about dynamic circuits, which I’ve written eight articles about and given a talk or two or (unrecorded) three about, but nonetheless due to the opportunity to play with the 127-qubit ibm_sherbooke.
