Director: Prof. Dr. ir. Rami Barends

Rami Barends has a PhD in physics (cum laude) from Delft University of Technology in 2009, working on the physical limitations of superconducting resonators for use as far-infrared detectors in astronomical telescopes. After his PhD he joined the University of California in Santa Barbara as a postdoctoral researcher, focusing on developing superconducting quantum bits for scalable quantum computing and achieving the surface-code fidelity thresholds for quantum gates. In 2014 he became a research scientist when the team merged with Google, performing the first scalable error correction experiments, the first digital quantum simulations, beyond-classical computing, and focusing on the fundamental limitations from correlated errors in quantum error correction. In 2021 he moved to the Jülich Research Center and leads the Institute for Functional Quantum Systems (PGI-13).

Pavel Bushev

Head of the experimental quantum computing group

Pavel Bushev obtained a Master’s degree cum laude in quantum radio-physics in Moscow Physical Technical Institute (Moskau, Russische Föderation) in 1997. During his doctoral research in Innsbruck University he worked on experiments with single trapped barium ion and a single photon. Pavel performed first experiments on quantum-limited motion detection and feedback for which he obtained a PhD degree cum laude. After a two-years postdoc in ETH Zürich and 2 years in Ulm, he worked as senior research assistant in Karlsruhe Institute of Technology for 4 years during 2009-2013 on investigations of superconducting qubits and hybrid quantum systems. In 2013 he joined the department of experimental physics in Universität des Saarlandes as assistant professor. The research topic of his group was mainly focused on quantum microwave photonics and metrology.

Asier Galicia

Asier Galicia is a physicist and electronic engineer graduated from the University of the Basque Country, Spain. After successfully defending his final project on Digital-Analog Quantum Computation under the supervision of Dr. Mikel Sanz, he decided to pursue a Master’s degree in Applied Physics at TU Delft. As part of his Master’s thesis he joined Taminiau’s Lab, supervised by Dr. C. E. Bradley and Dr. T. H. Taminiau. He worked with a Nitrogen-Vacancy centre, extending previously developed techniques to address 21 nuclear 13C spins surrounding it. He then used this new control to study dynamical nuclear polarisation, dephasing and spin diffusion in this complex coupled spin system. After completing his Master’s thesis, he contributed to the QuTiP python package and he is currently part of the admin team. Aiming to make meaningful contributions to the quantum computing field, he now decided to join the Institute for Functional Quantum Systems (PGI-13) as a PhD student under the supervision of Prof. Dr. Ir. Rami Barends and Dr. Pavel Bushev.

Senior Scientist

Markus Jerger

Manager of the Qubit Lab

After a two-semester peek at computer science while still in high school, Markus decided that physics was the more exciting subject to study. A few years later, he received his Diplom in physics from the University of Karlsruhe for theoretical work on geometric phases in charge and spin pumping. Seeking a more hands-on experience, he went to pursue a PhD in experimental quantum physics at the Karlsruhe Institute of Technology, working on multiplexed readout of superconducting artificial atoms.
