Quingo Runtime System

Along with quingo compilers, the Quingo runtime system which provides users the capability to program and simulate Quingo programs.

Installation

The Quingo installation comprises of two main steps:

Install the Runtime system and simulator

Install Quingo runtime system with required simulators using the following command:

pip install -e .

# for simulators used:
# The Tequila backend is not yet open source and needs to be installed separately.
git clone https://gitee.com/hpcl_quanta/tequila.git
pip install -e .

Upon success, it will automatically install the Quingo runtime system (this package), the SymQC simulator, the PyQCISim simulator and the QuaLeSim simulator.

Install the Quingo compiler

We can install mlir-based quingo compiler in two ways:

• Install the mlir-based Quingo compiler using the following command:

  python -m quingo.install_quingoc
  

• Download mlir-based Quingo compiler

  • Windows: unzip .zip file, add directory which contains the quingoc executable file to system environment PATH.
  • Linux: as the following sample usage, Quingoc will be installed to user defined directory, then add directory which contains the quingoc executable file to system environment PATH.

   quingo-compiler-0.1.4.sh -prefix=/home/user/.local
  

  • Macos: uncompress .dmg file, copy quingoc executable file to user defined directory, then add directory which contains the quingoc executable file to system environment PATH.

Usage

A simple example can be found in the directory src/examples. You can simply run the bell_state example by running:

cd src/examples/bell_state
python host.py

If everything runs correctly, you should see the following output:

sim res:  (['Q1', 'Q2'], [[0, 0], [0, 0], [1, 1], [1, 1], [0, 0], [0, 0], [0, 0], [1, 1], [0, 0], [1, 1]])

For different simulation backend, please refer to src/examples/sim_backend, which shows the use of SymQC, QuantumSim, and Tequila backend that are currently running stably.

For different simulation modes, please refer to src/examples/sim_exemode, which displays the output of two different simulation results currently available.

APIs of the Quingo runtime system

1. class Quingo_task:
   • 输入：
     • called_qu_fn: Path，qu文件路径。
     • called_func: str，调用 quingo 函数名。
     • debug_mode(optional): True or False。
     • qisa(optional): 前端指令集类型。
     • backend(optional): 后端模拟器类型。
2. function compile():
   • 输入：
     • Quingo_task: 待编译 qu 任务
     • params: Quingo_task 中调用函数 called_func 所需参数
   • 输出：qasm_fn：输出对应指令集文件(.qcis / .qi)
3. function execute():
   • 输入：
     • qasm_fn: Path，对应指令集文件(.qcis / .qi)
     • be_type: BackendType，模拟器后端类型
     • exe_config: 执行模式，ExeMode.SimShots、ExeMode.SimFinalResult、ExeMode.SimStateVector
   • 输出：sim_result：具体输出格式详见src/quingo/backend/quingo_result_format_spec.md
