QCirS

Overview

QCirS is a quantum circuit simulator.

Requirements

To build QCirS, followings are required:

• C++ compiler with C++14 capabilities
  • g++ 6.4 is recomended.
• Boost C++ Libraries version 1.66 or greater
  • to construct parser using boost::spirit::qi
• CMake 2.8 or greater

Building and Installing

$ git clone https://github.com/sndtkrh/qcirs.git
$ cd qcirs
$ mkdir build
$ cd ./build
$ cmake ..
$ make && make install

Example

To use quantum circuit library, you include qc/qcore.hpp in your .cpp files. For example, see example/dj.cpp. To compile this file, execute following commands:

$ cd ./example
$ g++ -std=c++14 dj.cpp -lqc -odj

This command generate executable file dj, and you can run it by:

$ ./dj

and you will get the result:

Result of applying D-J algorithm to a constant function:
The probability of results of measurement is [ 1 0 0 0 ].
(-0.707107,0)
(0,0)
(0,0)
(0,0)
(0.707107,0)
(0,0)

(0,0)
This function is constant.

Result of applying D-J algorithm to a balanced function:
The probability of results of measurement is [ 0 0 1 0 ].
