Adjacency Sampling reproduces all known Bell inequality classes in solved cases and generates over 129 million classes for the L_{3,3,3,3} scenario plus millions more for larger ones.
First metropolitan-scale quantum repeater achieving Bell nonlocality certification over 14.5 km using a new time-measurement multiplexed protocol with 78.6% fidelity.
New combinatorial proofs and circuit designs for quantum error correction reduce physical qubit overhead by up to 10x and time overhead by 2-6x for codes including Steane, Golay, and surface codes.
Higher-dimensional two-way QKD protocols using mutually unbiased bases and Heisenberg-Weyl operators yield secret keys for stronger individual attacks and improved robustness to collective eavesdropping via entropic uncertainty relations.
