I studied Mathematics and Physics concurrently at RWTH Aachen University. My PhD was supervised by Prof. Barbara Terhal. My first research project leading to a publication involved studying the computational power of certain quantum mechanical systems. In order to prove a complexity theoretic result my supervisor and I developed a way to map any quantum computation onto a model where each qubit has its own proper time, called the “Space-time circuit-to-Hamiltonian construction”. The paper was included in “IOP Journal of Physics A: Highlights of 2014 Selection”.
The focus of my PhD was on constructions that make a quantum computer robust against noise. These constructions make use of the beautiful geometry of curved and higher-dimensional spaces, as well as techniques ranging from cellular automata to deep learning. In particular, I showed how hyperbolic surfaces can be used to reduce the overhead cost for making quantum computers fault-tolerant.
Upon completion my PhD in 2017, I was awarded the UCLQ Postdoctoral Fellowship in Quantum Technologies. I deferred the Fellowship for a year to work full-time for PsiQ, a Silicon Valley based start-up building a general-purpose silicon photonic quantum computer.
During my fellowship I showed how to construct hyperbolic 4-manifolds in order to obtain high-performing fault-tolerance schemes for quantum computers.
Together with Jens Eberhardt I introduced “Balanced Product Quantum Codes” which are conjectured to have optimal scaling parameters.
Besides quantum error correction I analyzed properties of lattice models in curved spaces.
