These are software development kits (SDKs) that allow users to write quantum programs. While they can interface with hardware, they are primarily "services" in the sense that they provide the foundational codebase for quantum development.
When you add "free and open source" (FOSS) to the mix, you remove the black box. You can audit the code. You can run it offline. You can contribute bug fixes. And most importantly, you aren't locked into a single vendor's proprietary SDK. free open source quantum services
The quantum computing landscape has shifted from proprietary, closed-door research to an open ecosystem. Today, researchers, developers, and students can access real quantum hardware and sophisticated simulators for free. This report categorizes the available resources into two main segments: (the code used to build and simulate circuits) and Free Access Hardware Services (cloud platforms providing access to physical quantum processors). These are software development kits (SDKs) that allow
Here are the key services you can use today, completely free, with source code available on GitHub. You can audit the code
