"beamsplitter induce quantum superposition state for 1 phonon, interference between 2 phonons... transmitting half and reflecting other half back to its source... lithium niobate... quantum superposition, phonon both reflected and transmitted... quantum state collapse into 1 of 2 outputs... new kinds of calculations...phonons equivalent to photons... linear mechanical quantum computer.... directly integrates phonons with qubits... hybrid quantum computer combines linear with qubit-based quantum computers
