Benchmarking
Sandia National Labs released a direct, cross-platform measurement of quantum computational capability, highlighting the “distinct and difficult-to-compare routes to [quantum utility], using different qubit technologies and logical architectures.” Their quantum universal operation performance system (QUOPS) benchmarks the size of the largest computationally relevant quantum circuits that a machine can execute successfully and the speed at which it can execute them.
The Sandia team ran their QUOPS benchmark on systems from Quantinuum, Google, and IBM. Qantinuum’s Helios-1 delivered the highest performance. But, as an article from phys.org pointed out, current technologies will have to improve by about 100,000 times in order to crack standard encryption or deliver very large-scale, scientifically relevant results.

Terbium
Chemists from the University of Iowa, Los Alamos, Lawrence Berkeley, and the Colorado School of Mines separated terbium from other rare-earth metals under non-lab conditions. Their process did not require special controls of temperature, humidity, or pressure — opening ways to produce the material more easily and cheaply for imaging, electronics, and quantum technologies.
This work was published in Nature Communications.

AI-for-quantum
Q-CTRL released what it is calling the “industry’s first push-button solution for fully autonomous quantum computer bring-up, operation, and maintenance.” The “AI-for-quantum” company’s Boulder Opal software focuses on automated calibration and debugging.
