Pulse-level control of quantum systems is critical for enabling gate
implementations, calibration procedures, and Hamiltonian evolution which
fundamentally are not supported by the traditional circuit model. This level of
control necessitates both efficient generation and representation. In this
work, we propose pulselib - a graph-based pulse-level representation. A graph
structure, with nodes consisting of parametrized fundamental waveforms, stores
all the high-level pulse information while staying flexible for translation
into hardware-specific inputs. We motivate pulselib by comparing its feature
set and information flow through the pulse layer of the software stack with
currently available pulse representations. We describe the architecture of this
proposed representation that mimics the abstract syntax tree (AST) model from
classical compilation pipelines. Finally, we outline applications like
trapped-ion-specific gate and shelving pulse schemes whose constraints and
implementation can be written and represented due to pulselib's graph-based
architecture.
