The QPU sits in a 3-meter glass cube inside a purpose-built Quantum Computing Center about 35 km west of Seoul, with an 8,500 sqm quantum research complex under construction next door to anchor an industry-academia cluster developed with Incheon Metropolitan City. In November 2026 Yonsei is scheduled to swap the Eagle for IBM's 120-qubit Nighthawk QPU (square lattice, 218 tunable couplers, roughly 40 percent more computation at equivalent fidelity), which will be the first Nighthawk deployment outside an IBM-controlled site after IBM Miami.
