IBM's New Quantum Computing Chip, Loon, Could Lead to Useful Quantum Computers by 2029

IBM has developed an experimental quantum computing chip called Loon that demonstrates progress toward making useful quantum computers by 2029. The chip addresses error correction, a key challenge in quantum computing. IBM believes it can beat classical computers on some tasks by the end of next year. The company is working with startups and researchers to share its code openly for testing.
