IBM announces Nighthawk and Loon quantum chips

SMRTR summary

IBM unveiled two quantum chips, Nighthawk and Loon, designed to achieve "quantum advantage" by 2026, where quantum computers outperform classical computers. Nighthawk features 120 qubits with advanced couplers enabling 30 percent more computational complexity, while experimental Loon connects qubits both horizontally and vertically. Both chips reduce errors and support more demanding calculations, potentially unlocking new real-world quantum computing applications.
