Johannes Borregaard

Assistent Professor
J.Borregaard@[tudelft.nl]
Management Assistant: Helena Nwosu-Pronk

Johannes Borregaard obtained his PhD in theoretical quantum optics from the Niels Bohr Institute, Copenhagen in 2015 under the supervision of Prof. Anders Sørensen. This was followed by a two-year postdoc position (2015-2017) in the group of Prof. Mikhail Lukin at Harvard University, Boston and a three-year postdoc position (2017-2020) at the Centre for the Mathematics of Quantum Theory (QMATH), Copenhagen before joining QuTech in 2020 as an Assistant Professor.

Johannes’ focus early on has been to consider quantum technology in realistic settings subject to experimental imperfections. In his research, he tries to bridge the gap between quantum software and hardware working in the intersection of mathematics and physics. As a result, Johannes is working closely together with both experimental teams and quantum information theorists across Europe and the US. This allows to tailor protocols to the best suited hardware, which may consist of atoms, diamond defect centers, quantum dots, superconducting qubits, or squeezed light.

A substantial part of Johannes’ research evolves around quantum networks in a broad sense. This includes protocols for long-distance quantum communication and quantum sensor networks for enhanced metrology. An integral part of this is to exploit novel applications of quantum networks whilst outlining protocols for the implementation with specific hardware. In addition, Johannes is also very interested in investigating potential applications of the noisy quantum computing devices that exist today and in the near future.
