Quantum proof strengthens PSI's commercial case

As reported by TechCrunch, PSI says David Turturean, a member of the startup's technical staff and a recent MIT graduate, used early access to Anthropic's unreleased Fable 5.2 model to solve the Aaronson-Ambainis conjecture, an 18-year-old open problem in quantum computing.

The conjecture addresses how quantum computers might solve some problems faster than classical machines. Scott Aaronson, one of the researchers behind the problem, says he does not fully understand the proof but believes it is correct because it was autoformalized in Lean and explained by top researchers with whom PSI shared the result.

Turturean says the outcome is a negative result that rules out one possible route for high-speed quantum problem-solving, while leaving other avenues open. The episode also highlights how AI systems are starting to affect research workflows in mathematics and theoretical computer science, where outputs can be checked in formal code.

From data center optimization to physics-based products

PSI's current revenue comes from applying its tools to data center optimization, modeling variables such as heat, power, water and sound. The company says that work ties site performance and community impact directly to physical constraints, while serving as a nearer-term business line than frontier scientific discovery.

Over the longer term, PSI is aiming to turn theoretical physics advances into usable technologies. Chief executive Pines says the company is building loops in which AI proposes ideas, researchers validate them efficiently, and successful findings become exploitable facts of nature that can underpin new devices or systems.

The company also acknowledges the limits of AI-led discovery outside highly formal domains. While mathematics and some areas of computer science allow machine-generated results to be verified in code, fields such as physics and life sciences still require experimental confirmation, a challenge that is shaping PSI's validation strategy.

Questions about scientific standards are emerging alongside the technology. Jim Halverson, a Northeastern University professor who advises PSI, says best practices are still taking shape as AI-generated breakthroughs move into mainstream research, and he is attending an MIT summit next week where physicists plan to discuss how the field should respond.
