      abstract = {Mechanical systems have emerged as a compelling platform  for applications in quantum information, leveraging  advances in the control of phonons, the quanta of  mechanical vibrations. Experiments have demonstrated the  control and measurement of phonon states in mechanical  resonators, and while dual-resonator entanglement has been  demonstrated, more complex entangled states remain a  challenge. Here, we demonstrate rapid multi-phonon  entanglement generation and subsequent tomographic  analysis, using a scalable platform comprising two surface  acoustic wave resonators on separate substrates, each  connected to a superconducting qubit. We synthesize a  mechanical Bell state with a fidelity of F = 0.872 ± 0.002  , and a multi-phonon entangled N = 2 N00N state with a  fidelity of F = 0.748 ± 0.008 . The compact, modular, and  scalable platform we demonstrate will enable further  advances in the quantum control of complex mechanical  systems. },
