Unconventional Phonon Blockade in a Nanomechanical Resonator Coupled to Double Qubit System
摘要
Our theoretical and numerical study explores the phonon statistics of a nanomechanical resonator-qubit system which consists of one nanomechanical and two qubit modes in which the mechanical genre is coupled with both the qubit modes and the mechanical mode exhibits Kerr nonlinearity. We analytically apprehend the optimal conditions of anomalistic phonon blockade created by destructive interference between different transition pathways. Our numerically assessment values the second-order phonon correlation function and studies its dependence on different system parameters. It is observed that the analytically obtained optimal conditions are supported by the numerical results.
