"complex laser array at room temperature holds single atom in Paul trap... vibrations controlled/ utilized producing complex Gottesman-Kitaev-Preskill code, translating smooth, continuous quantum oscillations into clean, digital-like discrete states, making errors easier to spot/ fix... entangling 2 of these quantum states as qubits creates logic gate, enabling large-scale, highly hardware-efficient quantum-information processing... quantum logic gates with a reduced physical number of qubits, increasing their efficiency"
