  The quantum assembly language (QASM) is a popular intermediate representation
used in many quantum compilation and simulation tools to describe quantum
circuits. Currently, multiple different dialects of QASM are used in different
quantum computing tools. This makes the interaction between those tools tedious
and time-consuming due to the need for translators between theses different
syntaxes. Beside requiring a multitude of translators, the translation process
exposes the constant risk of loosing information due to the potential
incompatibilities between the different dialects. Moreover, several tools
introduce details of specific target hardware or qubit technologies within the
QASM syntax and prevent porting the code to other hardwares. In this paper, we
propose a common QASM syntax definition, named cQASM, which aims to abstract
away qubit technology details and guarantee the interoperability between all
the quantum compilation and simulation tools supporting this standard. Our
vision is to enable an extensive quantum computing toolbox shared by all the
quantum computing community.
