Translating electrical information into sound so that quantum states from superconducting qubits survive in storage for up to 30X longer

"phonons/ superconducting qubits both operate at GHz frequencies, perform well at low temperatures needed to preserve quantum states, long lifetimes... superconducting qubit on chip connected to tiny mechanical oscillator (serving as memory) interacting with electrical signals carrying quantum information... acoustic waves travel much slower than electromagnetic waves, enabling much more compact devices... mechanical vibrations do not leak energy, lengthening storage times... future: 3 to 10X faster interaction rate"
