  journal={Physical Review A},
An ever broader range of physical platforms provides the possibility to study and engineer quantum dynamics under continuous measurements. In many experimental arrangements the system of interest is monitored by means of an ancillary device, whose sole purpose is to transduce the signal from the system to the measurement apparatus. Here, we present a method of adiabatic elimination when the transducer consists of an arbitrary number of bosonic modes with Gaussian dynamics while the measured… Expand

Measurement-Induced Long-Distance Entanglement of Superconducting Qubits using Optomechanical Transducers
Although superconducting systems provide a promising platform for quantum computing, their networking poses a challenge because they cannot be interfaced to light, the medium used to send quantumExpand
Adiabatic Elimination for Multi-Partite Open Quantum Systems with Non-Trivial Zero-Order Dynamics
The main contributions of this paper are to show how the decomposition of the environment into $K$ components enables its efficient treatment, avoiding the quantum curse of dimension and to extend the results to the case where the target component is subject to Hamiltonian evolution at the fast time-scale.

Quantum-mechanics-free subspaces in composite systems with incompatible energy spectra
It is well established that quantum back action (QBA) can be reduced (or even completely canceled) in composite systems by engineering so-called quantum-mechanics-free subspaces (QMFSs) of commutingExpand
Unconditional Steady-State Entanglement in Macroscopic Hybrid Systems by Coherent Noise Cancellation.
This work proposes and analyze a generic approach to steady-state entanglement generation between two oscillators with different temperatures and decoherence properties coupled in cascade to a common unidirectional light field and finds its unconditional scheme to deliver a virtually identical performance when operated optimally.

Towards generic adiabatic elimination for bipartite open quantum systems
We consider a composite open quantum system consisting of a fast subsystem coupled to a slow one. Using the time scale separation, we develop an adiabatic elimination technique to derive at any orderExpand
Theory of a Quantum Scanning Microscope for Cold Atoms.
A scanning microscope is proposed and analyzed to monitor "live" the quantum dynamics of cold atoms in a cavity QED setup, such that the spatial distribution of motional eigenstates can be measured backaction free in single scans, as an emergent quantum nondemolition measurement. Expand
