Codex Found Six MIT Qubit Resonators and Completed Most Fixed-Qubit Targets Without Intervention

A first-party MIT and OpenAI case study reports researcher intervention to improve four of 40 target measurements on four fixed-frequency qubits. Noisy tunable-qubit scans still required expert judgment.

A Two-Path Coupler Could Quiet Superconducting Qubits Between Gates

A proposed single-junction circuit uses interference between two resonator modes to suppress idle crosstalk and activate fast entangling gates. Every reported performance result comes from modeling, not fabricated hardware.
