settings.
5 CONCLUSIONS AND FUTURE
WORK
This paper presented a preliminary validation of a
quality model for assessing the analyzability of classi-
cal–quantum software. The model integrates classical
and quantum metrics within a unified framework. Al-
though hybrid in design, this first evaluation focused
solely on quantum circuits due to the lack of accessi-
ble, mature hybrid code bases.
An empirical study with 109 participants showed
statistically significant differences in comprehension
performance across analyzability levels assigned by
the model. These results support the model’s utility
in distinguishing circuit complexity and reinforce the
need for structured metrics in hybrid software quality
evaluation.
However, this study is an initial step. Its scope
was limited to a homogeneous participant sample and
quantum-only code. Future work will expand the
study to include diverse profiles, assess prior exper-
tise, and test the model on real hybrid systems. Fur-
ther iterations will refine the metrics and assess their
scalability across tools and contexts, moving toward
a generalizable hybrid software quality assessment
framework.
