IBM to offer access to a dual-processor quantum system in 2027
Summary
IBM revised its quantum-computing roadmap as it aims to build error-corrected quantum computers before 2030. In 2027, it plans to offer access to a Nighthawk system that links two processors and includes a version with more than 500 programmable qubits.Key Facts
- IBM plans to pursue error-corrected quantum computers while continuing to offer general-purpose processors for users testing algorithms.
- IBM reduced its plan for linked Nighthawk processors from nine systems to two.
- The company says the total number of qubits planned for 2027 will remain unchanged despite the roadmap revision.
- IBM had previously planned to link three Nighthawk processors in 2026 to make a 360-qubit machine; its September Nighthawk r2 release is a single chip.
- Nighthawk r2 has 458 physical qubits, of which 120 are programmable.
- IBM says hardware-based qubit resets can speed up some operations by as much as 19 times.
