2025 in Review

The strongest way you, as a reader, give us an indication of what you’re interested in is click-through behavior — what links in the newsletter do you click on in order to learn more?

Which is why we pay a lot of attention to what you’re paying attention to. And it’s working. Quantum Campus spent several weeks of 2025 in the top 5 percent most-opened emails on our newsletter platform, and it consistently had a click-through rate of 10 percent. (There are about 65,000 newsletters being sent through the Beehiiv platform these days, and they have an average click-through rate of about 2.1 percent.)

Here are the quantum-related stories you were most interested in 2025, from #10 to #1.

• An item in Nature Physics on the fractional quantum Hall effect and how it “may be ideally placed to implement quantum computers.”

• A Department of Commerce announcement that $210 million in funding would be rescinded for six tech hubs, based in Alabama, Maine, Missouri, Oregon, Vermont, and Washington, as well as an archived version of the previous announcement of the funding by the Biden administration that was scrubbed from federal websites by the Trump administration.

• An overview by Quantum Campus of a report on the “global quantum R&D landscape” by MIT’s Initiative on the Digital Economy, in collaboration with Accenture. (Read the full report.)

• A Nature article from Caltech on a 6,100 neutral-atom qubit array using “optical tweezers.”

• A Nature article from Princeton on transmon-based qubits with millisecond coherence times.

• Reporting from The Register and Science about data manipulation accusations and counterclaims by competing current and former members of Microsoft’s Majorana team and the chip they released in 2025.

• The announcement of the $625 million renewal of the Department of Energy’s five National Quantum Information Science Research Centers.

• NVIDIA’s announcement of its forthcoming NVQLink classical GPU-quantum interconnect.

• IBM’s announcement of its Nighthawk chip, which is based on superconducting qubits. (IBM expected to ship its first Nighthawk chips to early users by the end of 2025 but has not subsequently touted any deliveries.)

• And here it is, you’re most-clicked story of 2025…Google’s claims in Nature of quantum advantage on second-order out-of-time-order correlators experiments, along with other researchers’ skepticism about the findings.
