"simultaneously retrieve data from multiple locations leveraging coherent superposition... stores large amounts/ different data types more effectively, boosting quantum computer speed/ effectiveness... transmon superconducting qubits robust against some noise types, direct surface acoustic wave phonons in desired locations... integrating transmon-controlled phonon phase gate into interferometer enables single phonon routing based on transmon's quantum state... QRAM realized connecting many routers in tree-like design"
