DQCsim Intel QS backend

A DQCsim backend plugin for the Intel QS simulator.

Usage

You need a DQCsim host plugin executable installed. You may use the dqcsim host, which you can install running cargo install dqcsim --features cli for a system-wide installation.

If you prefer to work on Python virtualenvs, you may install it running pip install dqcsim.

NOTE: poetry crashes if you try to install dqcsim. This is a known bug.

You will also need a frontend that generates the gate stream. The OpenQASM frontend has been used but the cQASM frontend could also be used. You may install them by running cargo install dqcsim-openqasm and pip install dqcsim-cqasm.

Once everything is installed, you can simulate your algorithm by running:

dqcsim MY_ALGORITHM.qasm dqcsim-iqs

or

dqcsim MY_ALGORITHM.cq dqcsim-iqs

Building

Requirements:

• Rust (stable)
• GCC or Intel C/C++ Compiler
• MPI 3.1+ libraries (MPICH recommended)
• CMake 3.14+

In order to use the CMake modules to find the dqcsim package, you need to install dqcsim through CMake and not through cargo or pip. Because of that you have to clone the dqcsim repository, build it manually and install it. It will only install the libdqcsim shared library and the CMake files.

git clone https://github.com/QE-Lab/dqcsim
cd dqcsim
cmake -B build -DCMAKE_BUILD_RELEASE .
cmake --build build --config Release --target all
cmake --build build --config Release --target install

You can then proceed to build this package.

cmake -B build -DCMAKE_BUILD_TYPE=Release .
cmake --build build --config Release --target all

This will install the dqcsim-iqs executable and libiqs shared library into your system.

cmake --build build --config Release --target install
