Qiskit

What Qiskit does

Qiskit is IBM's open-source software development kit for quantum computing, originally launched in 2017 and maintained by IBM Quantum Computing (a division of IBM Corporation, NYSE: IBM). The platform provides tools for building quantum circuits from quantum gates, transpiling workloads, running experiments via primitives (Sampler, Estimator, Execute), and visualizing and analyzing results. Qiskit is positioned as a backend-agnostic quantum execution layer with hardware plugins for IBM Quantum, IonQ, Amazon Braket, Azure Quantum, IQM, Rigetti, Quantinuum, Superstaq, AQT, and Alice & Bob, and it integrates with HPC environments via the Slurm plugin, QRMI, and Qiskit Serverless for quantum-classical orchestration. The product surface has expanded beyond the core SDK into addons (Map/Optimize/Execute/Post-process building blocks), Qiskit Function templates, the Benchpress benchmarking toolkit, and a community Qiskit ecosystem.

The primary users are quantum information science researchers, quantum algorithm developers, HPC organizations integrating quantum resources, and enterprise users applying quantum methods to optimization, simulation, quantum machine learning, and partial differential equation problems. The platform has accumulated 13M+ downloads, 7,000+ dependent projects, 1,200+ advocates across 70+ countries, and was named the preferred primary SDK by 69% of developers in the Unitary Foundation 2025 survey. Qiskit v2.4 was released in April 2026 and v2.5 in July 2026, indicating a roughly quarterly major-release cadence.

Qiskit operates as an open-source project under a freemium model with no direct licensing revenue; pricing is not publicly disclosed and the project is funded through IBM's overall R&D and strategic investments in quantum computing. Distribution is self-serve via pip install and GitHub, with additional enterprise-facing entry points through IBM Quantum Platform and the Amazon Braket and Azure Quantum marketplaces. Revenue, where it exists, is generated indirectly through IBM Quantum Platform subscriptions and hardware sales rather than through Qiskit licensing, and Qiskit-specific financials are not separately disclosed by IBM.

Revenue model

1. Open Source / No Direct Revenue: Qiskit is an open-source software stack distributed freely. As part of IBM's quantum computing initiative, it serves to grow the quantum computing ecosystem, drive adoption of IBM Quantum hardware and cloud platform, and establish IBM's position as the leading quantum computing provider. Revenue is generated indirectly through IBM Quantum Platform subscriptions and hardware sales rather than directly from Qiskit licensing.

Core offering

Qiskit is an open-source quantum computing software development kit (SDK) that provides researchers, developers, and HPC organizations with tools to build quantum circuits from quantum gates, transpile and compile circuits for execution, use primitives (Sampler, Estimator) to run experiments, and visualize and analyze results. It is backend-agnostic, supporting execution across IBM Quantum, IonQ, Amazon Braket, Azure Quantum, IQM, Rigetti, Quantinuum, Superstaq, AQT, and Alice & Bob hardware, and includes modular extensions such as Qiskit Addons, Function Templates, Qiskit Serverless, and the Benchpress benchmarking toolkit.

Product overview

Qiskit is IBM's open-source quantum computing software platform consisting of a core SDK (Qiskit) and ecosystem of extensions. The platform provides tools for quantum circuit building, transpilation (83x faster than competitors), and execution across multiple quantum hardware providers. Qiskit addons and Function templates provide modular algorithmic building blocks, while Benchpress enables performance benchmarking and Qiskit Serverless enables quantum-classical orchestration. The Qiskit ecosystem hosts community-contributed projects extending the platform's capabilities.
