Abstract: 
It is desirable to observe synchronization of quantum systems in the quantum regime, defined by the low
number of excitations and a highly nonclassical steady state of the self-sustained oscillator. Several existing
proposals of observing synchronization in the quantum regime suffer from the fact that the noise statistics
overwhelm synchronization in this regime. Here, we resolve this issue by driving a self-sustained oscillator
with a squeezing Hamiltonian instead of a harmonic drive and analyze this system in the classical and
quantum regime. We demonstrate that strong entrainment is possible for small values of squeezing, and in
this regime, the states are nonclassical. Furthermore, we show that the quality of synchronization measured
by the FWHM of the power spectrum is enhanced with squeezing.
