PPPL's Mark Martirez screens diamond qubit defects by simulating them as small molecules

Mark Martirez, a staff research scientist at the Princeton Plasma Physics Laboratory, simulates diamond qubit defects as isolated clusters of 16 to 30 atoms. Simulation turned up boron- and oxygen-based defects that could make useful qubits. They are candidates until someone grows and measures them.

Princeton physicists map a lower-energy path to fusion ignition that heats plasma before compressing it

Princeton Plasma Physics Laboratory calculations suggest heating plasma before raising its density could reach fusion ignition with far less energy. The Physical Review Letters paper keeps the Lawson criterion's endpoint and ranks the routes toward it by energy cost.

Windows in a NIF ignition cylinder released the brightest X-rays yet made in a lab

Ryan Lester and colleagues put windows in the gold cylinder that confines a National Ignition Facility shot. The escaping pulse reached tens of trillions of watts, on a par with the brightness of some red dwarf stars.

Princeton's PACMAN saw a plasma instability coming 200 milliseconds ahead

PPPL's framework closes a full control loop in about 20 milliseconds, which gives it roughly ten passes of warning before the instability it predicted would have arrived, on a real tokamak in five experiments.

PPPL's PACMAN framework closed a 20-millisecond AI control loop inside a real tokamak

Five experiments on the DIII-D tokamak let learned models predict plasma behaviour and command the heating, while error checking, conflict resolution and hardware limits stayed in stages where nothing was learned.

Lanyon AI raises $10.6M to make proofs, not plausibility, the acceptance test for AI code

A plasma-physics team is betting that aerospace and nuclear buyers will pay for machine-checkable proofs. The proof still stops where the specification stops.
