Installation

PRISM-Q is a Rust library. Add it to a project with Cargo:

cargo add prism-q                          # Rayon parallelism + faer SVD (default)
cargo add prism-q --no-default-features    # single-threaded, minimal dependencies

Or add it to Cargo.toml directly:

[dependencies]
prism-q = "0.16"

Feature flags

FeatureDefaultEnables
parallelyesRayon parallel kernels (≥14 qubits) and the faer SVD path for MPS
serializationnoserde derives for circuits and results
gpunoOptional CUDA backend (see the GPU guide)

Keep parallel on for performance

The published benchmarks were taken with parallel enabled. Without it, 16+ qubit runs fall back to single-threaded kernels and are not comparable to the baselines. Disable it only when you need a minimal-dependency, single-threaded build.

Building from source

git clone https://github.com/AbeCoull/prism-q
cd prism-q
cargo build --release

Running the test suite

cargo nextest run --all-features                          # unit + integration tests
cargo test --doc --all-features                           # doctests
cargo clippy --all-targets --all-features -- -D warnings  # lint

Use cargo test --all-features if cargo-nextest is unavailable.

Next: build Your First Circuit.
