Powerful tools and services for utility-scale workloads

The open-source Qiskit SDK provides tools for mapping problems to quantum circuits and preparing for execution. Qiskit also provides services to run, optimize, and orchestrate quantum workloads.

Circuit library

SDK

Build and visualize quantum circuits.

Transpiler

SDK

Use a powerful collection of optimized passes to tailor a pass manager. This supports circuit synthesis, optimization and scheduling for QPUs.

Primitives

SDK

Primitives are the fundamental interface for quantum computers. The Sampler and Estimator APIs define the inputs and outputs for QPUs.

Quantum info library

SDK

Construct operators and analyze outputs from primitive queries on QPUs.

Qiskit Transpiler Service

Service

Beta

Use this service powered by AI to enhance the transpilation from abstract quantum circuits to quantum ISA circuits .

Qiskit Runtime Service

Service

Execute Quantum ISA circuits using the primitives efficiently in a near-time environment with managed error mitigation and runtime compilation.

Qiskit Serverless

Tool

This tool runs quantum-centric supercomputing workloads across QPUs, CPUs and GPUs in the cloud.

Qiskit Code Assistant

Tool

Coming soon

Leverage generative AI to write quantum code using Qiskit.

Qiskit offers a simplified quantum workflow

Qiskit makes it easier to get started in quantum computing. It does so through Qiskit patterns: intuitive, repeatable sets of steps for quantum workflows. These patterns are modular, and can be combined in different ways to achieve different goals.
