DI Josef Moser
Josef studied at the Graz University of Technology and graduated as DI in 1988. In the same year, he started working as an analysis engineer and joined the Infineon Technologies Austria AG, formerly Siemens Bauelemente OHG Villach, in 1989. Being responsible for the management of diverse departments of different organizations, among others, for wet chemistry, ion implantation, deposition and maintenance, he gained experience in various manufacturing management positions. His intercultural skills were as well influenced by his 6 years stay in France. After starting up an operations organization for Ceramic semiconductors in the Czech Republic, he joined IFAT again in 2007. In his last job as Director Quality Management, Josef Moser was responsible for leading more than 120 employees in the Frontend operations Villach. He now acts as technical adviser and coordinator in funding projects with the focus on manufacturing innovation.

IFAT ion trap site: https://www.infineon.com/cms/en/product/promopages/trapped-ions/
The Eidgenössiche Technische Hochschule Zürich is among the world’s leading research institutions in the engineering and physical sciences. It is regularly ranked as the leading university in mainland Europe, and its reputation attracts internationally excellent researchers from all over the world.
The Trapped Ion Quantum Information (TIQI) group (https://tiqi.ethz.ch/) is situated in the Institute of Quantum Electronics and focuses on researching quantum information processing using trapped ions. The TIQI group is connected to other groups in Switzerland via the National Center in Research Excellence in Quantum Science for Information Technology (NCCR QSIT).
After coordinating with UIBK and our industrial partner IFAT (Infineon) to outline the specifications of the 3D traps in this project, the primary role of the TIQI group within PIEDMONS has been to characterise three-dimensional ion traps manufactured by IFAT. During the course of the project, researchers from the TIQI group have designed and built a flexible cryogenic setup to evaluate the performance of different ion traps.
A key part of this has been to develop a largely automated test suite to formally characterise ion traps, including automated ion loading routines, logging of experimental parameters and remote trap operation.
Christopher Axline, Post-doctoral Research Assistant
Chris has brought his background in superconducting qubits and experimental design for quantum optics to build a new cryogenic experimental apparatus for the testing of PIEDMONS traps in the TIQI group.

Prof. Jonathan Home is a full professor at ETH Zürich and founder of the ion trap group there in 2010, following PhD studies in Oxford and a post-doctoral research period at NIST with Nobel Prize winner David Wineland. His group has rapidly achieved pioneering results, including the largest instances to date of the paradigmatic squeezed and Schrödinger’s cat states of a harmonic oscillator, new types of scalable quantum logic gates, and the repeated application of stabilizer readout with feedback, which is likely to be the key element of any large-scale quantum computer. He has produced numerous publications including multiple works in each of Nature, Science, and Phys. Rev. Letters. Jonathan has received the 2015 Latsis Prize of the ETH Zürich and the 2013 Young-Researcher Award of the SAOT.
