Penn researchers fuse photons and excitons to slash AI energy costs
A team at the University of Pennsylvania built hybrid light-matter quasiparticles called polaritons inside a specially engineered microcavity. These polaritons replace some electronic switching steps with optical interference, cutting both latency and power draw during matrix multiplications common in transformer training. Early tests showed inference speeds rising by a factor of ten while energy per operation fell below one femtojoule.

Sony AI's Ace robot beats pros at table tennis using sim-to-real RL
Sony AI trained Ace on a MuJoCo physics simulator with 50,000 randomized ball trajectories per day, then transferred the policy to a real robot via domain randomization and on-robot fine-tuning. The system uses six synchronized event cameras at 10 kHz plus a wrist-mounted force-torque sensor, feeding data into a Soft Actor-Critic agent running on an NVIDIA Jetson AGX Orin. In 50 matches against top-ranked human players, Ace won 45.
