QMapping: A tool for architectural mapping of quantum circuits

Installation:

Download (clone) the source to a local directory and run the following commands
for source build:

1. Create a python virtual environment
    python3 -m venv <env name> 

2. Activate the environment
    source <env name>/bin/activate

3. Install the following packages 
    pip install cmake ninja setuptools setuptools_scm 

4. Install the QMapping tool
    python3 setup.py build 

Example

1. Using Python Interface:

    import PyQMapping
    
    #Layout as undirected graph
    layout = '''
    #L Q5
    Qubit: Q0 Q1 Q2 Q3 Q4 Q5 
    Coupling:
    Q0 Q1
    Q1 Q4
    Q1 Q2
    Q2 Q3
    Q3 Q5
    end
    '''

    input = '''
    OPENQASM 2.0;
    include "qelib1.inc";
    qreg q[27];
    creg meas[27];
    z q[0];
    x q[1];
    u3(pi/2,0,pi) q[2];
    cx q[0],q[2];
    h q[2];
    cx q[0],q[2];
    cx q[1],q[2];
    '''
    print(PyQMapping.qx_mapper(layout, input, 1))

2. Using Direct Executable

    ./build/qx_mapper <path to layout file> <path to qasm file> <path to output file>
