Square matrices with integer eigenvalues under entry permutations
Shuming Cheng, Siran Zhang
We investigate the problem of which multisets of integer entries yield integer eigenvalues in every square matrix arrangement? Combining module reduction with a dyadic criterion fo…

Resource-efficient quantum approximate optimization algorithm via Bayesian optimization and maximum-probability evaluation
Siran Zhang, Shuming Cheng
The quantum approximate optimization algorithm (QAOA) is a leading variational approach to combinatorial optimization, but its practical performance depends strongly on objective d…
