Projektbeschreibung
Quanteninformationsverarbeitung mit komplexen polyatomaren Molekülen
Das Verständnis komplexer Quantensysteme zu vertiefen und ihr technologisches Potenzial voll auszuschöpfen, zählt zu den größten Herausforderungen, der sich die Wissenschaft gegenübersieht. Das Streben nach dem Bau eines Quanteninformationsprozessors hat beispiellose Bemühungen ausgelöst, die Dynamik von Quantensystemen zu steuern und zu charakterisieren. Das EU-finanzierte Projekt QCOSMO zielt darauf ab, das Rechenpotenzial eines neuartigen Systems auf Basis eingefangener Ionen auszuloten und zu nutzen, das auf komplexen Bestandteilen beruht: polyatomaren Molekülen. Die Forschung soll die seit Langem bestehende Herausforderung überwinden, einzelne polyatomare Moleküle auf Quantenebene zu steuern und charakterisieren zu können. Die neuen Quantensteuerungsverfahren könnten an eingefangene Ionen gekoppelte polyatomare Moleküle als vielseitige Plattform für zukünftige Quantentechnologien etablieren.
Ziel
Reaching a fundamental understanding of complex quantum systems and fully harnessing their computational power for information processing is one of today’s greatest scientific challenges. The quest to build a quantum information processor has triggered unprecedented efforts to control and characterize dynamics in quantum systems. Here, trapped ion systems are one of the most promising architectures to realize large-scale quantum information processors.
In this project I aim to explore the physics and harness the computational potential of a novel trapped ion system with more complex individual constituents: polyatomic molecules. The proposed research tackles the long standing challenge of preparing, controlling and characterizing single polyatomic molecules at the quantum level.
The path towards these ambitious goals is centered around two high-level objectives: First, I will develop novel techniques to characterize quantum dynamics of polyatomic systems. In particular, I will quantify quantum coherence in ultrafast intra-molecular processes. This research will open a new window into intra-molecular processes with applications in quantum chemistry as well as biology. Second, I will develop and implement quantum control techniques for polyatomic molecules by coupling them to an atomic quantum information processor. Here, I will demonstrate the building blocks for a new scalable hybrid atom-molecule quantum information processor with ultrafast gate operations.
I am convinced that these new control techniques will lay the groundwork for research beyond the immediate project goals such as state-selective chemistry, precision measurements of fundamental constants, as well as scalable and ultrafast quantum computing. My strong interdisciplinary background in experiment design and characterization of quantum systems, and my track record in experimental quantum computation, put me in a unique position to reach the ambitious goals.
