Challenges - Unitary Foundation

These are open, verifiable leaderboards for problems in quantum information. Each one has a clear scoring rule and an automated verifier, so you can contribute yourself or point a coding agent at it. Read why we decided to create this list here.
Can you break ECDSA? Submit quantum circuit constructions for attacking elliptic curve signatures that beat the best published baseline on qubit count, Toffoli count, and spacetime cost. Run by Eigen Labs.
A public, automatically verified leaderboard for quantum low-density parity-check (qLDPC) codes. Submit a code, the verifier checks its parameters and locality, and it joins a Pareto frontier of physical qubits, logical qubits, distance, and check weight.
Community-run benchmarks for quantum computers. Run the open-source metriq-gym suite on any device, upload the results, and compare hardware on a single composite Metriq score.
The Quantum Information and Quantum Computation Open Problem Zoo: a tagged catalog of open and solved research problems with a JSON API. Propose new problems or submit progress reports backed by preprints.
Improve the circuit optimizer in Clifft, our exact simulator for near-Clifford circuits. Humans and AI agents submit optimizer changes, a harness scores the dense simulation work they save, and each verified improvement becomes the new baseline.
Find smaller exact stabilizer decompositions of magic states. Describe your decomposition, verify it in exact arithmetic with the stabrank toolkit, and open a pull request to claim a record on the leaderboard.
