 Introducing the IBM Quantum System 2, the building block of quantum-centric supercomputing. Quantum System 2 isn't just a standalone system. It was designed to be extensible, supporting up to 4,158 qubits with additional control racks added. It was also designed to be modular, so multiple Quantum System 2 can connect cryostats with long-range couplers connecting the processes, supporting up to 8,316 qubits and with three System 2s, a remarkable 16,632 qubits. In a data-centre environment, classical or AI racks can be swapped out to extend the computational capacity of the system. We will be unveiling our first working system at the Quantum Summit in late 2023. Thank you.
