IBM has upgraded its supercomputing capabilities with the introduction of Quantum System Two, the company’s first modular quantum computer. It serves as the foundation for IBM’s quantum-centric supercomputing architecture. The initial system in Yorktown Heights, New York, is powered by three IBM Heron processors and accompanying control electronics. Dario Gil, IBM’s Senior Vice President and Director of Research, emphasized the increasing role of quantum computers in advancing scientific exploration and spoke of plans to enhance the scalability and value of quantum systems through modular architectures. In line with their quantum computing roadmap, IBM also revealed Condor, a 1,121 superconducting qubit quantum processor utilizing cross-resonance gate technology. This design solves scalability issues and will inform future hardware designs. IBM’s Quantum Development Roadmap has been extended to 2033, with a focus on improving the quality of gate operations and increasing the size of quantum circuits that can be processed. Jay Gambetta, Vice President of IBM Quantum, highlighted the potential of quantum computers beyond quantum computing itself, and the need for a heterogeneous computing architecture that combines quantum technology with concurrent classical computing. This architecture forms IBM’s vision for future high-performance systems, referred to as “quantum-centric supercomputing”.
