Advanced Materials Science |
The Field-of-Expertise Advanced Materials Science is an interdisciplinary network of researchers at the TU Graz in chemistry, physics, architecture, mechanical engineering, civil engineering, electrical engineering and geodesy who discover, characterize and model materials, functional coatings and components. Thirty-three institutes from six faculties are presently involved.
Advanced Materials Day is the yearly meeting where the members of the FOE present their latest results. In 2019, the meeting will be held on September 26 at the Neue Technik campus in HS H "Ulrich Santner" in the Chemistry building.

Highly Integrated Ion-Traps for Quantum Computing Abstract: While not a new concept anymore, quantum computing is currently being pushed by numerous global players to speed up several currently intractable computer calculations, most notably in quantum chemistry and data security. Trapped-ion quantum bits (qubits) are, among others, a promising candidate for future quantum computers. These use the quantized energy levels of the valence electron to encode quantum information. A future quantum computer will require thousands of physical qubits to function correctly. As part of the PIEDMONS (https://www.piedmons.eu) project, we address two obstacles that currently prevent scaling-up the trapped-ion platform. Like most quantum computers, trapped ions require cryogenic temperatures to keep their quantum state. However, increasing the trap size to accommodate that many qubits will lead to significant heat dissipation due to wire resistance and dielectric losses. Thus, Alexander will characterize the oxide in the operating-frequency range (about 30MHz) and improve its quality to reduce dielectric losses. Secondly, he will investigate breakdown mechanisms between electrodes. The final target is an improved trap design that tolerates higher voltages and offers reduced losses and higher ion density. |
