Our Daily Quantum Update breaks down recent news into categories to make it easier for you to find the industry developments in which you are most interested. These articles don’t always explain what the core technology is or how it works. Luckily for us, there are some great resources on the web that do.

In each installment of this type of post, we’ve listed some of the best explainer pieces by authors like Russ Fein and Martin Ivezic, as well as by companies developing the technologies. For the latter group, we’ve tried to pick content rich in understandable technical signals and low in marketing noise.

We have not included deep research articles in these collections, though there might be a good survey article that sneaks in. We’ve tried to include content for beginners, enthusiasts, marketers, investors, policy makers, and, really, anyone who wants to learn more about the topic. Scan the listing and start with something that appeals to you. Jump around until you find something that is at your level of understanding and interest. The newest articles are at the top, with older ones appearing lower as you go.

Below the article links are references to other modalities covered in this series.

Of the four quantum modalities we have covered so far in this series (neutral atoms, superconducting, trapped ions, and photonic), none are as varied in their submodalities as silicon spin qubits. While the maximum number of qubits is low, in the upper teens, it has not stopped some of the vendors from predicting millions or billions of qubits per chip. Well, fine, but perhaps get back to us when you hit 1,000 qubits with high-fidelity 2-qubit gate fidelities. In any case, this general modality is fascinating and may, eventually, surpass superconducting as the low-temperature chip-oriented modality of choice.
