Perfect squeezing by damping modulation in circuit quantum electrodynamics

Understand

Dissipation-driven quantum state engineering uses the environment to steer the state of quantum systems and preserve quantum coherence in the steady state.

• We show that modulating the damping rate of a microwave resonator generates a vacuum squeezed state of arbitrary squeezing strength, thereby constituting a mechanism allowing perfect squeezing.
• Given the recent experimental realizations in circuit QED of a microwave resonator with a tunable damping rate [Yin et al., Phys.
