Qubits, or quantum bits, are the fundamental units of information in quantum computing, capable of existing in multiple states simultaneously due to superposition. This unique property allows qubits to perform complex calculations much faster than classical bits, which are limited to binary states of 0 or 1.

Today’s Brief Commentary: Today’s photo above is from the Quantum.Tech USA 2024 event in Washington, DC, in April. Thanks to the organizers for the image. Honestly, I thought I was smiling the whole time. It’s been a busy quantum spring…
Today’s Brief Commentary: I’m going to start today’s commentary with a quick thought I posted on LinkedIn: We don’t have a quantum computing workforce shortage. We have too many expert and talented people spread out over too many companies. I’ve…
Today’s Brief Commentary: This is a special issue of the newsletter in that instead of news articles and research papers, I’ve included several links that give the current state of quantum computing for finance. If you do a web search…
Today’s Brief Commentary: At the beginning of my talk at Quantum.Tech DC last week, I showed the above image as the bridge that quantum computing providers are trying to build and cross to give us Practical Quantum Advantage. I define…
Today’s Brief Commentary: Inspired by a discussion with a representative from Toshiba at the Quantum.Tech DC event this week, my links and comments today are related to annealing and optimization. In the quantum space, D-Wave is perhaps the best known…
Today’s Brief Commentary: Today’s first link in the post-quantum cryptography section is about OpenSSH adopting one of the NIST PQC standards. OpenSSH is a widely adopted open-source implementation of the Secure Shell (SSH) protocol, offering secure solutions for remote access,…
Today’s Brief Commentary: Prompted by a LinkedIn post by David Ryan and then my comment (and his response), today, I address the topic of a media or press kit for your website. Such a kit is a one-stop page that…
Today’s Brief Commentary: Today, we have two links to recent videocasts with me, three regarding post-quantum cryptography, and two for quantum computing. Each of the latter two categories includes variations of quantum hype. The first, from WIRED, is of the…
Today’s Brief Commentary: With the APS Global Physics Summit, NVIDIA GTC, and the Synopsys Executive Forum all in California last week, my attention turns to New York this week. I will do a short follow-up newsletter with my upcoming events…
Welcome to Wine Down Friday! Today, we explore the fascinating world of quantum technology with Bob Sutor, a leading expert in the field. From theoretical mathematics to leadership in AI, blockchain, and quantum computing, Bob shares insights into qubits, superposition,…
Today’s Brief Commentary: I’m pushing this newsletter out on a Sunday because two big industry events are coming up this week. The first is the NVIDIA GTC AI conference in San Jose, California. It runs from Monday the 17st through…
