Qiskit [kiss-kit] is an open source SDK for working with quantum computers at the level of pulses, circuits and application modules.
What can Qiskit do
Qiskit accelerates the development of quantum applications by providing the complete set of tools needed for interacting with quantum systems and simulators.
Access to circuits:
Access a rich set of well-studied circuits, which can be used as benchmarks, building blocks in more complex circuits, or as a tool to explore quantum computational advantage.
Execute code on multiple quantum hardware architectures, from superconducting qubits to trapped-ions.
Research and prototype machine learning, optimization and chemistry applications by building upon a library of quantum algorithms.
Study and reduce the impact of noise using built-in modules for noise characterization and circuit optimization.
