IBM Says 'Loon' Chip Shows Path to Useful Quantum Computers by 2029

IBM announced it has developed a new experimental quantum computing chip, which the company said constituted a milestone toward its goal of building practical quantum computers by 2029. The “Loon” chip integrates advanced quantum connections between qubits, making it more complex but potentially more powerful. IBM also unveiled a second chip, “Nighthawk,” which the company said could outperform classical computers on select tasks by 2026.
