TL;DR

IBM just laid out plans to build “Starling,” the world’s first large-scale, error-corrected quantum computer, by 2028 (with cloud access in 2029). Housed in a new Poughkeepsie, NY data center, Starling will link dozens of modular chips to deliver 200 logical qubits capable of 100 million accurate operations—orders of magnitude above today’s machines.

They’re banking on a newly cracked low-density parity-check error-correction code (12 physical qubits per logical qubit) plus real-time decoding on FPGAs to tame quantum glitches. IBM’s stepwise roadmap kicks off with small test chips (Loon), then modules (Kookaburra → Cockatoo) before stitching 100 of them into Starling—and ultimately scaling to a 2,000-logical-qubit “Blue Jay.” Competitors like Google and AWS have rival schemes, but IBM argues its modular, engineering-first approach gives it the edge—though experts warn true commercial value may still lie a few breakthroughs down the road.
