QCGPU-Rust

Features:

• Uses OpenCL kernels
• Runs cross platform
• Simulation of arbitrary quantum algorithms
• Optional simulation of decoherence
• Optimized for maximally entangled states
• Accelerated with GPUs
• Includes Example Implementations of Grover's algorithm, the Deutsch-Jozsa algorithm, the Bernstein-Vazirani algorithm and Shors algorithm
• Implements Hadamard, Pauli and phase gates, with support for arbitrary single qubit gate creation
• Support for controlled gates along with the toffoli and swap gate
• Support for measuring a state many times quickly

Prerequisites:

• OpenCL (Ensure that an OpenCL library is installed for your platform and that clinfo or some other diagnostic command will run).
• Rust (install here). Please use a nightly build.

If you wish to run the benchmarks, you must also install libquantum and qiskit.

• Libquantum can be installed from source, or from a package manager such as brew (brew install libquantum --devel) or apt (sudo apt-get install libquantum-dev). You should get the development version 1.1.1
• Qiskit can be installed through pip pip3 install qiskit.

Usage

First, add the crate to cargo.toml

[dependencies]
qcgpu = { git = "https://github.com/QCGPU/QCGPU-rust" }

Then just use the crate!

extern crate qcgpu;

fn main() {
    let mut state = qcgpu::State::new(2, 0);
    state.apply_gate(0, qcgpu::gates::x());

    println!("Measured: {}", state.measure());
    // 1
}
