This is a preview edition of Quantum Campus, which shares the latest in quantum science and technology. Read by more than 1,900 researchers, we are always looking for news from across the country. See something interesting? Be sure to share it.

IBM and the Japanese supercomputing center RIKEN completed what the team said was the largest and most accurate chemistry experiment ever performed on a quantum computer. The largest, these days, being a simulation of the electronic structure of a pair of iron-sulfur molecules, one with 50 electrons in 36 orbitals and another with 54 electrons in 36 orbitals.

The calculation ran across all 158,976 processors on RIKEN’s Fugaku supercomputer and a single IBM Heron quantum processor, all on-site at RIKEN.

To run the simulation, the researchers developed a new task assignment system. As Fugaku and Heron performed iterative calculations, passing information back and forth in a closed loop, this system assigned tasks to make sure both computers were working as much as possible, minimizing the time-to-solution, according to the team.

“Efficient orchestration matters because quantum and classical resources are precious,” said Hiroshi Horii, head of IBM Quantum Japan. “If your workflow is inefficient, and either resource, classical or quantum, is left idle at any point during the computation, you are wasting precious runtime that other researchers could use to tackle other important computations. Fugaku is a billion-dollar machine, and every second of its uptime is valuable. It’s crucial that those seconds aren’t wasted sitting around waiting for Heron to finish up a step in the calculation.”

CNBC surveyed industry analysts on the future of quantum data centers, in light of current interest in their impact on local economies and energy costs. Several of those interviewed argued that quantum computing may have a positive influence on energy demands, as the systems are likely to run some types of calculations more quickly and may use less power.

Read the CNBC article, with commentary for Microsoft, Moor Insights & Strategy, the European Centre for International Political Economy, S&P Global Market Intelligence, the Institute of International Finance, and UBS. The network also recently spoke to UBS about quantum computing companies more generally.

Stop typing reproductions and start vibing code. Wispr Flow captures your spoken debugging flow and turns it into structured bug reports, acceptance tests, and PR descriptions. Say a file name or variable out loud and Flow preserves it exactly, tags the correct file, and keeps inline code readable. Use voice to create Cursor and Warp prompts, call out a variable like user_id, and get copy you can paste straight into an issue or PR. The result is faster triage and fewer context gaps between engineers and QA. Learn how developers use voice-first workflows in our Vibe Coding article at wisprflow.ai. Try Wispr Flow for engineers.
