Jeroen Elzerman is a Senior Lecturer in Quantum Photonics at the Department of Electronic & Electrical Engineering and the London Centre for Nanotechnology at University College London. He holds a Royal Society Wolfson Research Merit Award (2012 – 2017).
After his undergraduate studies in Applied Physics at Delft University of Technology (the Netherlands), Jeroen started his PhD in Leo Kouwenhoven’s Quantum Transport group at the Kavli Institute for Nanoscience Delft. There he focused on building an electron spin qubit and demonstrated how to electrically isolate and read out single electron spins in semiconductor quantum dots. After his PhD, Jeroen wanted to learn about optical techniques for controlling semiconductor spins. He therefore moved to Switzerland to work with Atac Imamoglu in the Institute for Quantum Electronics at ETH Zurich. After initial efforts with semiconductor nanowires, he turned his attention to coupled self-assembled quantum dots (“artificial molecules”) when he became a senior scientist.
Jeroen moved to UCL in 2012 to start his own experimental group, which is focused on quantum photonics with electronic and nuclear spins in semiconductor nanostructures. He has published over thirty papers with almost 4000 citations and has an h-index of 18.
Awards and honours
Jeroen’s current research centres around solid-state quantum photonics. His group uses laser light to manipulate the quantum state of electronic and nuclear spins in semiconductor nanostructures. The goal is to controllably couple multiple spins confined in real or artificial atoms, and build a small quantum network that can store and process quantum information. This could lead to a new class of devices, which exploit the underlying quantum mechanical nature of matter to perform tasks that are beyond the capabilities of current classical technology.
The experimental techniques that his group specializes in are confocal microscopy at low temperatures (down to 4 K) and high magnetic fields (up to 10 T), as well as high-resolution resonant spectroscopy and time-resolved resonance fluorescence from single quantum emitters. A variety of systems and devices are studied, including self-assembled single and coupled quantum dots (“artificial atoms and molecules”), semiconductor nanowires, and naturally occurring spins in bulk semiconductors.
Recent results include the demonstration that two coupled electron spins can be used to form a highly coherent singlet-triplet spin qubit, which is robust against both electric and magnetic noise coming from the semiconductor environment.
