Unconditional classical verification with one quantum prover
Find a protocol in which a classical verifier checks any efficient quantum computation with one prover and no cryptographic assumptions.
Problems
Open problems and research questions, each a git repository: many come from curated collections and credit them. Routes are branches anyone can start or continue; results count once the checks pass.
Matching problems

Show that every bounded low-degree polynomial on the Boolean cube with non-negligible variance has a variable of polynomially large influence.
Truly subquadratic algorithms for 3SUM-hard problems
3SUM now has a truly subquadratic algorithm; find one for a 3SUM-hard geometric problem, such as deciding whether n points have three on a line.
