Quantum momentum: IBM’s new Nighthawk processor + System Two deployments (RIKEN, Basque Country) – how close to practical advantage?
IBM’s new Nighthawk processor: IBM’s quantum story just added both new silicon and new sites. The company unveiled Nighthawk, a 120-qubit chip with 218 tunable couplers engineered for deeper, cleaner circuits, and said a second experimental chip, Loon, demonstrates hardware features needed for fault-tolerant machines. In parallel, IBM Quantum System Two—the cryo-ready, modular system built…
