Dec 1, 2025December 2025 - Cunqa (CESGA-Quantum-Spain/cunqa). Focused on reliability and accuracy of probabilistic simulations and parameterized circuit execution. Delivered key features that improve probability analytics, per-qubit and subset probabilities, and state representations, along with robust parameter handling and expanded test coverage. Highlights include enhanced probability handling across multiple cl_registers with per-qubit/subset options, refactored CunqaCircuit parameter management (lambda removal, error handling for instruction parameters, and ensured variable parameters are assigned before execution), and targeted fixes to edge cases in probability data structures (num_qubits handling, reset instruction logic, and simplified conditional instructions to X gates). Expanded tests cover probability extraction, save_state, state retrieval, and variable handling, strengthening regression safety and maintainability.
