Realization of strong coupling between two different quantum systems is important for fast transferring quantum information between them, but its implementation is difficult in some hybrid quantum systems.Here we propose a scheme to enhance the coupling strength between a single nitrogen-vacancy center superdry baseball top and a superconducting circuit via squeezing.The main recipe of our scheme is to construct a unitary squeezing transformation by directly tuning the specifically-designed superconducting circuit.Using the experimentally accessible parameters of the circuit, we find that the coupling strength can be largely amplified by applying the squeezing transformations to the system.This provides a new path mpu63zm/a to enhance the coupling strengths in hybrid quantum systems.
