About Polystacks
The open source discovery platform and registry for heterogeneous, accelerated, and quantum computing.
Our Purpose
Modern computing is shifting beyond homogeneous general-purpose architectures. Cutting-edge computational breakthroughs now depend on specialized, heterogeneous architectures — from quantum processors and neuromorphic chips to custom domain accelerators, GPUs, and hybrid quantum-classical workflows.
Polystacks provides a centralized, community-maintained index of the open source software powering this shift. We help researchers, systems engineers, and computational scientists discover libraries, find links to algorithm implementations, and navigate an evolving ecosystem of specialized toolchains.
What We Index
Frameworks & SDKs
Full-stack development environments, instruction set architectures, and quantum/classical runtime libraries (e.g., Qiskit, Cirq, PennyLane).
Simulators & Emulators
State-vector, tensor network, stabilizer, and noise model simulators enabling classical verification of quantum circuits.
Compilers & Optimization
Intermediate representations, circuit synthesis, routing, and transpiler passes targeted for NISQ and fault-tolerant architectures.
Error Correction & Cryptography
Fault-tolerant codes (surface codes, LDPC), syndrome decoders, and post-quantum cryptographic primitives.
Curation & Quality Standards
Polystacks combines imported repository metadata with community submissions and editorial review. Coverage and review status vary by project:
- Open Licensing: Check the upstream license before using a project. Missing license metadata does not establish permission to use its code.
- Active Maintenance: Repository metadata is a snapshot. Check upstream releases, issues, and commits to assess current maintenance.
- Reproducibility: Project pages may include papers and notebooks. A link or listing does not certify that an implementation has been independently reproduced.
