Chinese Humanoid Startup LimX Dynamics Raises $200M at $2.2B Valuation

PsiQuantum, a UK-founded quantum computing startup, is building a photonic quantum computer designed to solve problems current machines would take millions of years to address. The company has raised $1 billion, is constructing facilities in Chicago and Australia, and is one of only two firms (alongside Microsoft) to reach the third stage of a government quantum evaluation program. Its claims are bold, from reducing drug development timelines to four minutes, but the company now faces a critical prove-it moment as it approaches commercialization.

Google is expanding its tensor processing unit business beyond internal use and Google Cloud, now actively marketing TPUs to emerging cloud providers that have previously focused exclusively on renting Nvidia GPUs. The company has approached neocloud operators like Nscale as part of a competitive push against Nvidia's dominant market position in AI chips. This marks a strategic shift from Google's historical practice of keeping TPUs confined to its own infrastructure.

X Square Robot, a Chinese embodied-AI company, proposes an integrated software stack as the foundational recipe for general-purpose robots, combining data collection, world models, and action models rather than assembling separate perception and control systems. The company emphasizes data quality over scale, using a wearable rig for human demonstrations with physical validation on real robots, achieving performance comparable to all-robot datasets at roughly 20-fold lower collection cost. This approach challenges the field's lack of consensus on how to build robots with transferable intelligence across tasks and machines.

Samsung Electronics is accelerating the opening of its first chipmaking plant in Yongin, south of Seoul, to 2029, moving the timeline forward by up to two years. The acceleration responds to surging demand for memory chips driven by the AI infrastructure boom. The plant represents a significant capacity expansion for the company amid intensifying competition in chip manufacturing.
