ETH Zurich is one of the leading international universities for technology and the natural sciences. It is well known for its excellent education, ground-breaking fundamental research and for implementing its results directly into practice. Founded in 1855, to researchers, it today offers an inspiring working environment, to students, a comprehensive education. ETH has 20600 students from over 120 countries, including 4100 doctoral students. About 530 professors currently teach and conduct research in engineering, architecture, mathematics, natural sciences, system-oriented sciences, and management and social sciences. ETHZ regularly appears at the top of international rankings as one of the best universities in the world. 21 Nobel Laureates have studied, taught or conducted research at ETHZ, underlining the excellent reputation of the university.
The Quantum Device Lab at ETH Zurich is one of the core experimental partners of the consortium. It has more than 12 years of experience in developing and operating superconducting circuits for quantum information processing, and more generally for quantum science and technology. It will develop and operate a fully functional copy of the envisaged quantum computer at their site. The Quantum Device Lab will leverage its expertise in designing, fabricating and operating superconducting multi-qubit devices (WP 2). Furthermore, they will take the lead in engineering a cryogenic control and readout environment (WP 3), and develop experimental software for general sample characterization, the control and readout of qubits, and for data analysis (WP 4).
Since January 2012 Andreas Wallraff is a Full Professor for Solid State Physics in the Department of Physics at ETH Zurich. He joined the department in January 2006 as a Tenure Track Assistant Professor and was promoted to Associate Professor in January 2010.
Previously, he has obtained degrees in physics from Imperial College of Science and Technology, London, U.K., Rheinisch Westfälische Technische Hochschule (RWTH) Aachen, Germany and did research towards his Master’s degree at the Research Center Jülich, Germany. During his doctoral research he investigated the quantum dynamics of vortices in superconductors and observed for the first time the tunneling and energy level quantization of an individual vortex for which he obtained a PhD degree in physics from the University of Erlangen-Nuremberg.
During the four years he spent as a research scientist at Yale University in New Haven, CT, USA he performed experiments in which the coherent interaction of a single photon with a single quantum electronic circuit was observed for the first time. His research is focused on the experimental investigation of quantum effects in superconducting electronic circuits for performing fundamental quantum optics experiments and for applications in quantum information processing.
His group at ETH Zurich engages in research on micro and nano-electronics, with a particular focus on hybrid quantum systems combining superconducting electronic circuits with semiconductor quantum dots and individual Rydberg atoms, making use of fast and sensitive microwave techniques at ultra-low temperatures.
Christopher Eichler is a Senior Scientist in the Quantum Device Lab at ETH Zurich. After obtaining Diploma degrees in physics and music from the Goethe University and the Hochschule für Musik und Darstellende Kunst in Frankfurt/Main, he completed a PhD thesis at ETH Zurich in 2013. From 2014 to 2016 Christopher Eichler was a Postdoctoral fellow at the Physics Department of Princeton University before rejoining ETH Zurich in 2016.
The research work of Christopher Eichler focuses on studying superconducting circuits to explore fundamental aspects of quantum physics and develop novel devices for information processing applications. Major results of his previous research include the sensitive detection and characterization of quantum microwave radiation using parametric amplifiers, the quantum limited detection of electron spin resonances in silicon, and the first experimental implementation of a quantum variational algorithm using superconducting circuits.
