IBM Quantum

IBM Quantum is the division of International Business Machines Corporation dedicated to advancing the field of quantum computing. Launched publicly in 2016, it provides cloud-accessible quantum processors and a comprehensive software stack for researchers, developers, and enterprises. The initiative is central to IBM's strategy in next-generation computing, aiming to build practical quantum systems capable of solving problems intractable for classical supercomputers. Its work spans hardware development, algorithm creation, and the cultivation of a global quantum ecosystem.

History

The roots of the division trace back to long-term research within IBM Research, particularly at locations like the Thomas J. Watson Research Center. A pivotal moment came in 2016 with the launch of the IBM Quantum Experience, which allowed public cloud access to a quantum processor via the internet. This was followed by the introduction of the IBM Q Network in 2017 to foster collaborations with academic institutions, national laboratories, and industry partners. Key milestones include demonstrating quantum volume increases, deploying the IBM Quantum System One in 2019, and launching the IBM Quantum System Two in 2023 as a modular platform for future quantum-centric supercomputers. Leadership under Dario Gil and Jay Gambetta has been instrumental in steering its roadmap.

Quantum hardware

The division develops superconducting qubit processors, known as IBM Quantum processors, which are housed in advanced dilution refrigerators at facilities like the IBM Quantum Computation Center in Yorktown Heights, New York. Processors are named sequentially (e.g., IBM Eagle, IBM Osprey, IBM Condor) with increasing qubit counts and performance, as measured by quantum volume. The IBM Quantum System One integrates these processors into a unified, commercial-grade system, with installations globally, including at the Cleveland Clinic and the University of Tokyo. The IBM Quantum System Two architecture, unveiled in 2023, is designed for scalability and interoperability with classical high-performance computing resources.

Quantum software and services

Central to its software ecosystem is Qiskit, an open-source software development kit for quantum programming in Python (programming language). The IBM Quantum Platform provides cloud-based access to quantum systems and simulators, along with runtime services for executing quantum circuits and algorithms. Managed services offered through the IBM Quantum Network help enterprises explore applications in fields like chemistry, optimization (mathematics), and machine learning. The software stack is designed to abstract hardware complexity and integrate with classical computing workflows from partners like Red Hat.

Research and development

Its research and development efforts are conducted globally across IBM Research labs, including the Almaden Research Center and Zurich Research Laboratory. Core R&D focuses on improving qubit coherence times, error correction via codes like the surface code, and developing quantum algorithms for practical use cases. The team publishes extensively in journals like Nature (journal) and Science (journal), and collaborates on projects with entities such as the University of Chicago, MIT, and CERN. A major focus is the roadmap toward achieving quantum advantage in specific industrial applications.

Partnerships and ecosystem

The IBM Quantum Network forms the core of its partnership strategy, comprising members like JPMorgan Chase, Boeing, Samsung, and ExxonMobil, as well as institutions like Fraunhofer Society and Oak Ridge National Laboratory. These collaborations explore quantum computing for financial modeling, materials science, and logistics. The division also engages with government agencies, including the United States Department of Energy and the European Union, on large-scale quantum initiatives. Educational outreach through Qiskit and partnerships with universities worldwide aims to grow the quantum workforce and developer community.
