qSim-cpp

Quantum computer simulator library

I'm building this to learn C++ and Quantum Information Theory simultaneously, so don't be surprised if they're both wrong. Instead, feel free to create a new issue or a new pull request so you can rub in exactly what I did wrong in a concise, well commented manner.

Thanks x

Installation

Requirements

• C++14

Instructions

Download or clone qSim-cpp into some/directory/qSim

Usage example

// A confused qubit
// confused.cpp

#include "qSim.h"

using namespace qsim;

int main() {
    // initialize a |0> qubit
    math::Ket qubit = states::z0;

    std::cout << "qubit:\n";
    qubit.print();

    // apply a Hadamard gate to qubit
    qubit *= gates::H;

    std::cout << "confused qubit:\n";
    qubit.print();
}

From this directory, compile confused.cpp using your compiler of choice:

$ g++ -std=c++14 -I some/directory/qSim/include confused.cpp -o confused

Then run your compiled file:

$ ./confused

Should output something like:

qubit:

| 1 |
| 0 |

confused qubit:

| 0.707 |
| 0.707 |

For more examples and usage, please refer to the examples.
