AI Data Centers Demand More Than Copper Can Deliver

SummaryIn data-center terms, scaling out involves linking computers, while scaling up packs more GPUs into a computer, challenging copper’s physical limits.Copper cables face a phenomenon at high data rates at high data rates that necessitate wider wires and more power, complicating a data center’s dense connections.Point2 and AttoTude propose radio-based cables, offering longer reach, lower power consumption, and narrower cables than copper, without the cost and complexity of optics.Startups aim to directly integrate radio cables with GPUs, easing cooling needs and enhancing data-center efficiency.How fast you can train gigantic new AI models boils down to two words: up and out.In data-..

This tiny chip could change the future of quantum computing

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems. Crucially, it’s made with standard chip manufacturing, meaning it can be mass-produced instead of custom-built. This opens the door to quantum machines far larger and more powerful than anything possible today.

This strange magnetism could power tomorrow’s AI

Scientists in Japan have confirmed that ultra-thin films of ruthenium dioxide belong to a newly recognized and powerful class of magnetic materials called altermagnets. These materials combine the best of two magnetic worlds: they’re stable against interference yet still allow fast, electrical readout—an ideal mix for future memory technology.
