Main Research Directions and Funded Projects
A prominent view among the quantum computing and quantum information community, e.g., as expressed by John Preskill [pp. 1 in Quantum 2, 79 (2018)], is that
“...we are now in the early stages of exploring a new frontier of the physical sciences, what we might call (...) the entanglement frontier. (...) Now, for the first time in human history, we are acquiring and perfecting the tools to build and precisely control very complex, highly entangled quantum states of many particles, states so complex that we can’t simulate them with our best digital computers or characterize them well using existing theoretical tools."
My current research is an effort to develop the necessary theoretical tools—and approaches for their practical implementation in experiments —to address crucial challenges and foundational questions encountered at this entanglement frontier. Specifically, I am currently actively pursuing three main directions of research:

My current research is an effort to develop the necessary theoretical tools—and approaches for their practical implementation in experiments —to address crucial challenges and foundational questions encountered at this entanglement frontier. Specifically, I am currently actively pursuing three main directions of research:
(i) on the side of quantum information theory, by rethinking the theory of high-dimensional and complex many-body entanglement beyond the idealized paradigm of unrestricted local operations and classical communication (LOCC) on asymptotically many copies, but rather tailoring it to the requirements of real-world quantum-optical devices and quantum networks, an endeavour recently funded by the Austrian Science Fund (FWF) via the Stand-Alone Project “Entanglement-based certification of quantum technologies (EBCQT)".
(ii) and on the side of quantum computing theory, by developing theoretical frameworks for exploring, benchmarking, and utilizing soon available hybrid classical-quantum high-performance computing hardware as part of the recently funded Flagship Project “High-Performance integrated Quantum-Computing (HPQC)" by the Austrian Research Promotion Agency (FFG). (iii) At the same time I seek to pursue foundational-physics questions at the boundary of statistical mechanics, thermodynamics, and quantum optics to study fundamental limitations on the control, preparation, and measurement of quantum systems and the required resources (funded by the JTF Large Grant “Emergence of Objective Reality: From Qubit to Oscilloscope"). |
