"""The myQLM library allows the user to instantiate a myQLM ``Circuit`` from an
OpenQASM 2.0 code. MyQLM is able to parse most of the standard gates, and allows
us to complete the missing gates by linking them to already defined ones. We
call the function :func:`qasm2_to_myqlm_Circuit` to generate the circuit from
the qasm code."""
