- Timothy Proctor at Sandia National Laboratories and colleagues developed the QUOPS (quantum universal operation performance system) score, which measures a quantum computer's qubits and computational operations to gauge whether it can run a given algorithm.
- Google, IBM, and Quantinuum quantum computers all scored below 2000 on the benchmark — none came close to the scores required for practical applications.
- FeMoco molecule analysis (relevant to nitrogen fixing) and breaking modern cryptography would both require QUOPS scores more than 100,000 times higher than what today's machines achieve.
- Quantinuum's Helios-1 earned a score of about 40 when configured as a fault-tolerant machine, the error-correcting architecture researchers consider the only viable path to useful quantum computing.
- Sam Stanwyck at Nvidia, which collaborated on the project, called the benchmark a 'reality check' that lets researchers see how QUOPS scores shift with small design tweaks.
- Wolfgang Mauerer at the Technical University of Applied Sciences Regensburg said the benchmark is useful but added that 'what quantum compute power really is, that is not yet fully understood, and that cannot be captured in the benchmark.'
Why it matters: For the first time, researchers have a concrete yardstick showing that today's best quantum machines from Google, IBM, and Quantinuum are more than 100,000-fold short of what's needed for cryptography-breaking or FeMoco simulation — giving the field a baseline to measure real progress toward fault-tolerant quantum computing rather than chasing raw qubit counts.
