Fractional OAM charge ℓ=1.5 induces an optimal 67.5° GKP lattice rotation that reduces error rate 23.9× with <0.2% loss in Fisher information and yields 41% higher metrological capacity.
Spinmons are introduced as qubits from transmon-Andreev spin entanglement, with coherent control via Zeeman splitting, gates, and flux drive, showing robustness to flux and charge noise.
Lattice QED is established as a quantum error-correcting code beyond stabilizers, with explicit recovery operations constructed via quantum reference frames for gauge and fermionic sectors.
Hybrid pulsed-CW architecture for optical quantum computation with experimental proof-of-principle of ultrafast homodyne detection on pulsed single-photon states yielding W(0,0) = -0.153.
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.
A literature review synthesizing developments in quantum Wasserstein distances, their applications, and unresolved questions.
