Abstract
Section titled āAbstractāWe report the design of a diamond-based honeycomb phononic network, in which\na mechanical resonator couples to three distinct phononic crystal waveguides.\nThis two-dimensional (2D) phononic network extends an earlier study on\none-dimensional (1D) phononic networks with closed mechanical subsystems. With\na special design for the phononic band structures of the waveguides, any two\nneighboring resonators in the 2D network and the waveguide between them can\nform a closed mechanical subsystem, which enables nearest neighbor coupling and\nat the same time circumvents the scaling problems inherent in typical large\nmechanical systems. In addition, the 2D network can be attached to a square\nphononic crystal lattice and be protected by the large band gap of the phononic\ncrystal shield. Honeycomb phononic networks of spin qubits with nearest\nneighbor coupling can serve as an experimental platform for quantum computing\nand especially topological quantum error corrections.\n
