In our group, we develop analytic and numerical methods for modeling the quantum dynamics of coherent solid-state and hybrid systems, such as superconducting quantum circuits, opto- and nanomechanical devices, or individual electronic spins. A central goal of this research is to identify improved control schemes and protocols for quantum communication and quantum information processing applications. In addition, we also explore novel quantum many-body phenomena that arise in such artificial quantum devices with specifically engineered properties and interactions.

Abstract: We propose a scheme for high-fidelity quantum state transfer between distant cascaded three-level cavity-QED nodes by designing the external driving pulses. The scheme achieves near-unity transfer…
Nature Physics
Abstract: In a phononic quantum network, quantum information is stored and processed within stationary nodes defined by solid-state spins, and phonons carry the information between nodes. Phonons have a number…

Abstract: The distribution of entanglement across distant qubits is a central challenge for the operation of scalable quantum computers and large-scale quantum networks. Existing approaches rely on…

Abstract: Single microwave photons can be transferred through a hot quantum channel.

Abstract: We describe a novel scheme for the generation of stationary entanglement between two separated qubits that are driven by a purely thermal photon source. While in this scenario the qubits remain in a…

Abstract: We study the collective decay of an initially inverted ensemble of two-level emitters in two distinct scenarios: when coupled to a squeezed photonic reservoir and when interacting with a…
Physical Review Letters
Abstract: We study the directed transport of bosons along a one dimensional lattice in a dissipative setting, where the hopping is only facilitated by coupling to a Markovian reservoir. By combining numerical…
Physical Review Research
Abstract: We optimize matrix-product state-based algorithms for simulating quantum circuits with finite fidelity, specifically the time-evolving block decimation (TEBD) and the density-matrix renormalization…
npj Quantum Information
Abstract: We study a generic cavity QED setup under conditions where the coupling between the two-level systems and a single bosonic mode is significantly degraded by low-frequency noise. To overcome this…
Polariton Chemistry
Abstract: This chapter presents a basic introduction to the ground‐state phases of ultrastrongly coupled light–matter systems, starting with a brief historical review of the Dicke model and the associated…
