Abstract summary: We demonstrate a trapped-ion system with two competing dissipation channels, implemented independently on two ion species co-trapped in a Paul trap. By controlling coherent spin-oscillator couplings and optical pumping rates we explore the phase diagram of this system, which exhibits a regime analogous to that of a (phonon) laser but operates close to the quantum ground state with an average phonon number of $barn10$.

Abstract: We demonstrate a trapped-ion system with two competing dissipation channels, implemented independently on two ion species co-trapped in a Paul trap. By controlling coherent spin-oscillator couplings and optical pumping rates we explore the phase diagram of this system, which exhibits a regime analogous to that of a (phonon) laser but operates close to the quantum ground state with an average phonon number of $\bar{n}<10$. We demonstrate phase locking of the oscillator to an additional resonant drive, and also observe the phase diffusion of the resulting state under dissipation by reconstructing the quantum state from a measurement of the characteristic function.

Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation [49.1574468325115]
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Signatures of Dissipation Driven Quantum Phase Transition in Rabi Model [0.0]
We investigate the equilibrium properties and relaxation features of the dissipative quantum Rabi model. We show that, in the Ohmic regime, a Beretzinski-Kosterlitz-Thouless quantum phase transition occurs by varying the coupling strength.

Dynamical emission of phonon pairs in optomechanical systems [6.259066812918972]
Multiphonon state plays an important role in quantum information processing and quantum metrology. We propose a scheme to realize dynamical emission of phonon pairs based on the technique of stimulated Raman adiabatic passage in a single cavity optomechanical system. Our proposal can be extended to achieve an antibunched $n$-phonon emitter, which has potential applications for on-chip quantum communications.

Dissipative entanglement generation between two driven qubits in circuit quantum electrodynamics [0.0]
We explain the mechanism of entanglement generation in terms of an interplay between unitary Landau-Zener-Stuckelberg transitions. In this way, we found that the steady state of the system can be tuned to be arbitrarily close to a Bell state.

Quantum Zeno effect in self-sustaining systems: suppressing phase diffusion via repeated measurements [0.0]
We study the effect of frequent projective measurements on the dynamics of quantum self-sustaining systems. We show that by subjecting the system to repeated measurements of heterodyne type at an appropriate repetition frequency one can significantly suppress phase diffusion without spoiling the semiclassical dynamics.
