Biphoton Hofstadter’s butterfly and entanglement engineering in a synthetic photonic lattice

Based on a coupled resonator array, we theoretically construct and numerically simulate a nonlinear quantum optics platform to dynamically control the Bloch wavevector. By scanning the modulation parameters ( α,ky), we reproduce the Hofstadter’s butterfly structure in the biphoton energy spectrum and reveal clear corre...
