Qiskit 0.42.0 documentation¶
Qiskit is open-source software for working with quantum computers at the level of circuits, pulses, and algorithms. Additionally, several domain specific application API’s exist on top of this core module.
The central goal of Qiskit is to build a software stack that makes it easy for anyone to use quantum computers, regardless of their skill level or area of interest; Qiskit allows one to easily design experiments and applications and run them on real quantum computers and/or classical simulators. Qiskit is already in use around the world by beginners, hobbyists, educators, researchers, and commercial companies.
