Package: qualesim
StartThe QuaLeSim(Quantum Lego Simulator) is an adapted version of DQCSim. For quantum circuit simulation, you can simulate QUIET-s and QCIS instruction by it.
And what's more, now the QuaLeSim is integrated into the backend of Quingo, you can use it directly after installing quingoc and quingo-runtime. More inforemations is available in [[#Install]]InstallThe QuaLeSim now is only for Linux platform.环境准备：Linux platform withpython>=3.6Rust # if you don't have rust, make sure you have'curl'to install rust in the setup.py .安装说明：You can get the source code from giteegit clone git@gitee.com:quingo/qualesim.git
 cd qualesim
 git checkout task/fix-bugs
 git submodule update --init --recursive 
 # you must have the limits of authority of quiet-parser, dqcsim-qcis, 
 # dqcsim-quiets, dqcsim-tequila, dqcsim-quantumsim.
 pip install -r requirements.txt
 pip install .  # the step may be very slow, you can use command below.
 			   # python setup.py bdist_wheel
 			   # cd <path-to-qualesim>/target/python/build/bdist.linux-x86_64/wheel
 			   # pip install xxx.whl
 			   # 存在LLVM的情况下会很慢，暂时不清楚原因，正在修改中。externs:# The Simulator is for QCIS and QUIET-s, and now the quingo-0.2.3 can generate QCIS 
 and QUIET-s
 # so you can install quingoc and quingo-runtime to use it.
 # quingoc:

 1. add eigen 
 	mkdir <tmp>
 	cd <tmp>
 	cp /mnt/share/eigen-3.4.0.zip .
 	unzip eigen-3.4.0.zip
 	
 	# then copy Eigen and unsupported to quingo-compiler/extern and like
