ticit

Ticit is a pure-Rust implementation of SymFT with CPU and an experimental CUDA backend utilizing cutile-rs, plus a stim-like procedural TableauSimulator for Clifford + T circuits.

Installation

Build from source

# rust
git clone https://github.com/inmzhang/ticit.git
cd ticit
cargo build --release

# python
uv sync --project ticit_py

CLI binary

cargo install ticit

Rust crate

cargo add ticit

Python package

uv add ticit

Rust API

See the Rust API documentation.

use ticit::{Circuit, SamplerOptions};

let circuit = Circuit::from_text("M 0\nOBSERVABLE_INCLUDE(0) rec[-1]")?;
let mut compiled_sampler = circuit.compile(SamplerOptions::default())?;
let result = compiled_sampler.sample(1_000, false)?;

Use sample_with_seed(shots, seed, bit_packed) when reproducible records are required. Setting bit_packed packs eight record bits into each output byte.

Python API

See the Python API reference.

import ticit

compiled_sampler = ticit.Circuit("M 0").compile(backend="cpu")
result = compiled_sampler.sample(shots=1_000, seed=42)

Benchmarks

See ticit vs SymFT vs Clifft for CPU and GPU results, methodology, and caveats.

AI acknowledgement

Extensive use of generative AI is an explicit initial goal of this project: to port SymFT's C++ implementation to Rust and experiment with Rust portable SIMD and cuTile-rs. AI tools assist with implementation, review, analysis, benchmarking, and documentation; human contributors make and verify the substantive design, validation, and release decisions.
