▪️ We construct a process that remains causal even when the parties share arbitrary entangled auxiliary systems, yet has no purification in any finite auxiliary dimension. The obstruction persists on an open set of nearby processes. (OQP 43)
We built PSI as the AI native laboratory fueling the physics takeoff, leveraging superintelligence to vastly expand the pace and scale of fundamental and applied research physicists can pursue. Come build with us.
