Function swapGate

Source 
pub unsafe extern "C" fn swapGate(
    qureg: Qureg,
    qubit1: c_int,
    qubit2: c_int,
)
Expand description

Performs a SWAP gate between \p qubit1 and \p qubit2. This effects \f[ \begin{pmatrix} 1 \ & & 1 \
& 1 \ & & & 1 \end{pmatrix} \f] on the designated qubits, though is performed internally by three CNOT gates.
