Quantum information processing relies on the precise control of non-classical states in the
presence of many uncontrolled environmental degrees of freedom. The interactions …

In driven-dissipative systems, the presence of a strong symmetry guarantees the existence
of several steady states belonging to different symmetry sectors. Here we show that when a …

In dissipative quantum systems, strong symmetries can lead to the existence of conservation
laws and multiple steady states. In this Letter we investigate a strong symmetry for bosonic …

Reservoir engineering is a powerful tool for the robust generation of quantum states or
transport properties. Using both a weak-coupling quantum master equation and the exact …

We demonstrate the extension of coherence between all four two-electron spin ground
states of an InAs quantum dot molecule (QDM) via nonlocal suppression of nuclear spin …

We study an “observable-based” notion of equilibration and its application to realistic
systems like spin qubits in quantum dots. On the basis of the so-called distinguishability, we …

We develop and implement a model for decoherence in time-dependent transport. Inspired
in a dynamical formulation of the Landauer-Büttiker equations, it boils down into a form of …

We study the influence of narrowed distributions of the nuclear Overhauser field on the
decoherence of a central electron spin in quantum dots. We describe the spin dynamics in …

Spin collective phenomena including superradiance are even today being intensively
investigated with experimental tests performed based on state-of-the-art quantum …

We develop a method for entangling operations on nuclear spins surrounding a negatively
charged boron vacancy (VB-center) point defect in hexagonal boron nitride (hBN). To this …
