Quantum Computing
PsiQuantum's blueprint for a warehouse-scale photonic quantum computer
MIT Technology Review takes the deepest public look yet at PsiQuantum's plan to build a massive quantum computer out of light: a data-center-scale hall holding some 100 six-foot stainless-steel cabinets, each fed by liquid helium that holds the photonic hardware a few degrees above absolute zero. The feature lays out how the company intends to leap directly to a utility-scale, fault-tolerant machine rather than iterating through small prototypes — the industry's most aggressive photonic bet, reported here by an independent outlet rather than the company itself.

X Square Robot opens its embodied-AI stack — benchmarked, so far, only by itself
Chinese embodied-AI firm X Square Robot laid out its full-stack recipe for general-purpose robots in a sponsored IEEE Spectrum feature: a wearable dual-gripper data rig whose trajectories are validated by physical playback on a real robot (~85% data-validity rate, claimed ~20x cheaper than teleoperation), the event-based WALL-WM world model, and the Wall-OSS-0.5 vision-language-action model, with code being released openly. The concrete releases and its reported >20-billion-yuan (~US$2.9B) valuation are noteworthy, but every performance claim rests on the company's own robots and benchmarks — and the article itself is paid vendor content, so treat the results as unverified until independent replication.
