QIQC Open Problem Zoo

Field notes

QIQC OP organizes 108 quantum information and quantum computation questions across six fields and 58 topics, with separate views for unsolved, solved, random, and recently edited entries. The homepage reports 99 unsolved questions and 9 solved ones. Its sample entry formalizes a Welded Tree path-finding problem: an algorithm receives coherent adjacency-list oracle access and must determine whether producing an entrance-to-exit path requires exponentially many queries. Contribution and GitHub links are visible alongside the catalog.
