Forschungszentrum Jülich
Forschungszentrum Jülich (FZJ) is a member if the Helmholtz Association of German Research Centers and is one of the largest interdisciplinary research centers in Europe. The research of FZJ focuses on three major areas: information, energy, and bioeconomy. FZJ is organized in various research institutes, each one addressing a specifically defined scientific goal or societal challenge. The work on GEQCIS project will be performed in the Peter Grünberg Institute (PGI), named after the FZJ 2007 Nobel Laureate. FZJ will contribute both its experimental and theoretical techniques to the creation of the German superconducting quantum computer. Its major engagement in recent years in the Europe-wide effort (for example in the frame of EU project OpenSupeQ) to achieve such functionality will enable it to spring quickly into the key problems that are currently faced in making reliable quantum computing a reality, and to enable the unique German capabilities that are available to make further advances towards this ambitious goal.
On the experimental side, FZJ will use its matured expertise in assembling and integrating all the working parts of the quantum computer. Its existing state of the art infrastructure in cryogenics and electronics will permit it to immediately begin testing the new concepts that it will develop for new quantum chip design, in conjunction with other partners. It will contribute to the testing, charachterization and scalable readout of many-qubit gate implementations, and evaluate the value that brings to the system-level functioning of the quantum computer. It will develop new calibration techniques for the achievement of a new, higher-precision level of operation. It will be one of the first labs to integrate and test the parametric amplifiers developed at the corporate partner Infineon, and confirm that they are superior for the task of rapid and accurate measurement of qubits.
On the theory side, FZJ will direct its strong team towards the solution of problems in the creation of a reliable superconducting quantum computer. It will lead in the paradigm of co-design, in which theory and experiment iterate together towards best functionality. It will deploy control theory techniques integrated with system identification that will permit the most robust functionality in the face of hardware variability. It will provide modeling at a variety of levels, from basic device functionality, to electromagnetic modeling of couplers, to the design of most-effective quantum error correction schemes. Theory will also work towards maintenance of the entire software-control stack, and towards the linkage of the German quantum computer system to the leading HPC (high-performance computing) capabilities of FZJ.
PI Pavel Bushev: 1991-1997 Studying of physics in Moscow Physical Technical Institute and in Lebedev Physical Institute (Moskau, Russische Föderation). 2000-2004 doctoral research on the topic “Interactions between single trapped barium ion and a single photon”. Also, he performed a first experiments on quantum-limited feedback of the motion of a single trapped ion for which he obtained a PhD degree cum laude from Universität Innsbruck (Austria). 2004-2006 postdoc in ETH Zürich and 2007-2009 in Ulm. 2010-2013 senior research assistant in Karlsruhe Institute of Technology with a research focus on hybrid quantum systems in the framework of BMBF project QUIMP. In 2013 he joined the department of experimental physics in Universität des Saarlandes as Junior Professor. The research topic of his group was mainly focused on developing of methods of quantum microwave photonics and its application for the development of optical/microwave quantum memories in spin doped solids and for quantum metrology. During his scientific career he acquired a rather unique and versatile experience working in different field of experimental quantum physics. He contributed to superconducting quantum circuits, hybrid quantum systems, quantum optics, microwave photonics, spin doped solids and quantum gravity.
Since November 2019 Pavel Bushev is the head of the Central Quantum Computing Lab for the OpenSuperQ project. There, he will incorporate best practice from all members of the consortium, including best European experimental groups in ETH Zurich and Chalmers. Complementarity of both OpenSuperQ and GeQCoS projects makes contribution of Pavel Bushev very desirable for the needs of the German consortium. He will contribute to GeQCoS with unique expertise on scalable superconducting qubit characterisation and optimized read-out.
