Research
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.

The Vacuum in Ultrastrong Coupling Cavity Quantum Electrodynamics
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…
Engineering protected cavity-QED interactions through pulsed dynamical decoupling
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…
Dynamical cluster-based strategy for improving tensor network algorithms in quantum circuit simulations
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…
Unraveling Superradiance
Physical Review Letters
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…
Unified Interface Model for Dissipative Transport of Bosons and Fermions
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…
The bosonic skin effect
SciPost Physics
Abstract: We study the incoherent transport of bosonic particles through a one dimensional lattice with different left and right hopping rates, as modelled by the asymmetric simple inclusion process (ASIP).…
Toward high-fidelity quantum information processing and quantum simulation with spin qubits and phonons
Physical Review B
Abstract: We analyze the implementation of high-fidelity, phonon-mediated gate operations and quantum simulation schemes for spin qubits associated with silicon vacancy centers in diamond. Specifically, we show…
Can We Observe Nonperturbative Vacuum Shifts in Cavity QED
Physical Review Letters
Abstract: We address the fundamental question of whether or not it is possible to achieve conditions under which the coupling of a single dipole to a strongly confined electromagnetic vacuum can result in…
Entangling microwaves with light
Science
Abstract: Quantum entanglement is a key resource in currently developed quantum technologies. Sharing this fragile property between superconducting microwave circuits and optical or atomic systems would enable…
