IBM Quantum systems

The first and foremost cloud-based quantum computing systems.

Overview

Since 2016, when it made the world’s first quantum computer available through the IBM Cloud, IBM Quantum Experience has remained the premier place for researchers, industry professionals, developers, and students to access cutting edge quantum hardware.

IBM Quantum currently hosts a fleet of 18 quantum systems, offering access through our open and premium systems. All quantum systems deployed by IBM Quantum are based on superconducting qubit technology, as the control and scalability of this technology pave a clear path to achieving quantum advantage with these systems.
