Quantum Computing Simulator

## Feature

- Simple quantum calculation using command line tool is possible.
- Quantum state operation or quantum circuit execution is possible with Python package.
- Support four types of quantum states: 1) quantum state vector, 2) density operator, 3) stabilizer state, 4) matrix product state.
- Other quantum computing services or simulators can be used as backend (The followings are supported).
    - [qulacs](https://github.com/qulacs/qulacs)
    - [IBM Quantum(IBMQ)](https://quantum-computing.ibm.com/)
    - [Amazon Braket(LocalSimulator,AWS,IonQ,Rigetti,OQC)](https://aws.amazon.com/braket/?nc1=h_ls)
- High-speed quantum circuit execution using GPU is possible (build from source code).

## Requirements
