Q
Open source

Qiskit

IBM’s Python SDK for building, transpiling and running quantum circuits.

The most common entry point, and the one most tutorials assume.

Quantum SDK
R
Open source

ROS 2

The middleware layer most robotics stacks are assembled on top of.

Not a framework so much as the ecosystem everything else assumes.

Robotics
M
Open source

MuJoCo

A physics engine for contact-rich robotics and biomechanics simulation.

Fast contact dynamics — which is exactly the part sim-to-real strains hardest.

Simulation
C
Open source

Cirq

Google’s Python framework for writing circuits against specific hardware topologies.

Closer to the device than most SDKs — useful when connectivity matters.

Quantum SDK
P
Open source

PennyLane

Differentiable quantum programming that plugs into standard ML autodiff frameworks.

The default choice for variational work — and for meeting barren plateaus in person.

Quantum SDK
S
Open source

Stim

A very fast stabiliser-circuit simulator built for error-correction research.

The reason large surface-code experiments are simulable at all.

Error Correction
L
Open source

LeRobot

Datasets, models and tooling aimed at real-world robot learning.

Notable for treating shared datasets as the bottleneck, which they are.

Robotics
D
Open source

Drake

Model-based design, simulation and verification tooling for robotics.

Heavier than MuJoCo and more rigorous about the model underneath.

Simulation
G
Open source

Gymnasium

The maintained standard API for reinforcement-learning environments.

The interface almost every RL codebase expects to find.

Robotics
l
Open source

liboqs

The Open Quantum Safe project’s library of post-quantum cryptographic algorithms.

Where to start when a fleet needs a migration plan rather than an opinion.

Security
A
Cloud service

Amazon Braket

Managed access to quantum hardware from several vendors behind one API.

Useful for comparing platforms without signing separate agreements.

Cloud
A
Cloud service

Azure Quantum

Microsoft’s cloud service for running jobs against partner quantum hardware.

The other front door to the same set of machines.

Cloud
Q
Open source

Qiskit Qec

Qiskit quantum error correction framework

The reference simulator for open quantum systems.

Error Correction
t
Open source

tsim

Fast universal quantum circuit sampler for QEC based on ZX stabilizer rank decomposition

Fast universal quantum circuit sampler for QEC based on ZX stabilizer rank decomposition — actively maintained.

Error Correction

Open source

ardupilot

ArduPlane, ArduCopter, ArduRover, ArduSub source

ArduPlane, ArduCopter, ArduRover, ArduSub source — very widely used, actively maintained.

Robotics
I
Open source

IsaacLab

Unified framework for robot learning built on NVIDIA Isaac Sim

Unified framework for robot learning built on NVIDIA Isaac Sim — well established, actively maintained.

Robotics
O
Open source

OpenCat-Quadruped-Robot

An open source quadruped robot pet framework for developing Boston Dynamics-style four-legged robots that are perfect for STEM, coding & robotics education, IoT robotics applications, AI-enhanced robotics application services, research, and DIY robotics kit development.

An open source quadruped robot pet framework for developing Boston Dynamics-style four-legged robots… — well established, actively maintained.
