6/ Diverse computational schemes: PQC proves versatile in performing various QC techniques, ranging from universal schemes like MBQC to non-universal ones such as boson sampling. Moreover, PQC is adaptable to classical photonic (aka optical) computing.

7/ Proof of the quantum advantage: it's not just theoretical. PQC systems have manifested their potential in real experiments, showing a quantum computational advantage in several cases (Jiuzhang, Borealis).
