Qics - Quantum Idealistic Computer Simulator

Qics is an Idealistic, Quantum Computer Simulation Library. It works by holding a Quantum Register as a Matrix, and then multiplying that against various Gate Matrices. For more information about the working, see the src directory for the source code, or see examples/node.js or the Usage Section for information on the usage of the module.

Features

• A 'Universally Complete', Quantum Circuit Based Simulator
• Gate Expansion Function (To make a single qubit gate work on a register with multiple qubits)
• Relatively Simple To Use

---

Usage

Currently the library is available using Node.js and NPM. To install the module, use the command:

npm install qics

Then you are able to use the module. When it's installed, Qics exposes two classes, qics.Register and qics.gates.

qics.Register is the main class, and is the basis of the simulator. It is used like any other class using the new keyword. Once initiated, there is a number of methods, see below or the Documentation (To be written).

qics.gates exposes all of the single qubit gates as 2D arrays. It also has some static methods, such as generateGate(). Again, see the documentation.

Example simulation:

// Import the module
const qics = require('qics');

// Create a new Quantum Register with 3 Qubits
const reg = new qicks.Register(3);

// Apply some gates.
// Hadamard Gate
reg.applyGate('H', 1);
// CNOT Gate, with control as qubit 1, and the
// target as qubit 3
reg.applyGate('CNOT', 1, 3) ;

// Now measure the register. Should return either "000" or "101"
console.log(reg.measure());

Build

First you need to clone the repo from github:

git clone git://github.com/adamisntdead/qics.git
cd qics

Then install the dependencies:

npm install

Then you can run the build script:

npm run build

This will build the module, and output to the dist folder. If you want to build for clint side (i.e. in the browser), run npm run build:all and then it will output qics.js and qics.min.js to the dist folder.

Tests

To run the test for this module, after cloning and installing, run:

npm run test

And it will run all of the tests.
