Yonsei University upgrades IBM Quantum System One to Nighthawk R2 processor
Yonsei University and IBM said on the 4th that they held a launch ceremony at the Quantum Computing Center on Yonsei's Songdo International Campus in Incheon, South Korea, after fitting the IBM Quantum System One with the Nighthawk R2 processor. It replaces the 127-qubit (physical) Eagle processor the system was first built on in 2024. IBM says the Nighthawk R2 has 120 programmable qubits (458 physical qubits in total including auxiliary functions), runs more than 100,000 circuits per second (25 times the Eagle's throughput), and keeps median two-qubit gate error around 0.2%. Its qubits use a square-lattice layout, with most connecting to four neighbors, instead of the Eagle's honeycomb layout. Yonsei plans to use it for bio-AI research, including a study of Leigh Syndrome.
