ABOUT ME
I am a researcher with interests in various subfields of quantum computing.
This encompasses classical simulation methods, stabiliser formalism and magic state model, characterisation and benchmarking protocols, and compilation of quantum circuits.
I am interested in the theory and construction of (approximate) unitary t-designs and random quantum circuits.
Among others, unitary designs play an important role in many benchmarking and characterisation protocols.
From a practical point of view, exact unitary designs however have several disadvantages and hence the focus has shifted towards approximating them with random circuits.
Here, a thorough analysis of their convergence properties is key to guarantee the proper functioning of the protocol and, for instance, also plays an important role in quantum supremacy experiments.
I am currently working on adapting characterisation and benchmarking protocols to random circuits, thereby combining rigorous performance guarantees with minimal practical assumptions, making them more easily accessible to experimentalists.
Currently, I am working on a federally funded project on trapped-ion quantum computers which involves close collaboration with experimental and industrial partners.
Through this, I have become increasingly interested in the practical challenges of building quantum computers.
Moreover, I have started to work on gate set design and on compilation methods using multi-qubit gates native to ion trap architectures.
During my PhD, I worked on advanced methods based on the stabiliser formalism and the Clifford group.
In particular, I have become interested in stabiliser-based simulation methods such as Wigner functions on discrete phase space and decompositions in stabiliser frames (e.g. robustness of magic, stabiliser extent, dyadic negativity).
I worked on the closely related resource theory of magic and I am interested in resource-theoretic questions in quantum computing.
