CSE Professor Qian Zhang's research on differential testing of quantum software stacks was awarded an ACM SIGSOFT Research Highlight. SIGSOFT Research Highlights are selected from leading software engineering conferences to show recent, significant, and exciting results that are also of general interest to the computer science research community.
This highlight paper, called QDiff, was originally published in ASE 2021. It is for testing quantum language constructs, compilers, and backend simulators. Quantum hardware is in its imperfection; understanding different outcomes across a quantum software stack can help construct a robust quantum ecosystem in the future.
