Qiskit

What it is

Qiskit is an open-source framework that enables developers to build, simulate, and run quantum computing programs. It provides tools for creating quantum algorithms and executing them on both simulators and actual quantum computers.

Qiskit stands out as the leading open-source framework for quantum computing, offering comprehensive tools and direct access to IBM's quantum hardware.

When it fits — and when it doesn’t

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited hardware access outside IBM Quantum ecosystem

   Primary integration is with IBM Quantum, other providers require additional setup or are not fully supported

2. 02

   Performance limitations in large-scale quantum circuit simulation

   Simulating circuits with high qubit counts on classical hardware can be resource-intensive and slow

What it does well

• Integration with IBM Quantum hardware and simulators

• Support for quantum circuit design, simulation, and execution

• Optimization tools for compiling circuits to run on real devices
