You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Hangxi Li, Doctoral Student, Quantum Technology, Microtechnology and Nanoscience. The seminar is titled: Scaling Up Flip-Chip-integrated Superconducting Quantum Processors. Abstract: Large-scale quantum processors are needed to achieve quantum computational advantage and implement useful quantum algorithms. To this end, flip-chip integration technologies are widely used to route input/output signals to the qubits in a scalable way. In this talk, I will show you our successful development of flip-chip quantum devices with qubit coherence and gate fidelities that are similar to our single-chip performance. Building upon this work, I will also show you our design and characterization of our newly fabricated 25-qubit flip-chip-integrated superconducting quantum processors.

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Guido J.L. de Reijer, Doctoral Student, Applied Chemistry, Chemistry and Chemical Engineering. The seminar is titled: Catalyst Design for the Conversion of Biomass into Chemicals Abstract: To transition towards a sustainable chemical industry, renewable sources, such as biomass derived from plants, trees, and waste, must be explored. Carbohydrates present in biomass can be converted stepwise into aromatics: building blocks used to produce e.g., plastics, medicine, and paints. This reaction requires the use of a catalyst, which is a material or chemical that accelerates reactions. In my research, I design, synthesise, and test new catalysts for the conversion of one type of biomass-derived furans, 2,5-dimethylfuran, into monoaromatics. These catalysts are typically microporous solids, called zeolites, that exhibit great thermal stability, shape-selectivity, and tunability. To illustrate, altering the metals present in the catalyst influences the activity and acid sites of the catalyst. Whereas altering the microporous framework, e.g., by introducing mesopores, influences the product distribution and lifetime of the catalyst. Through exploring different parameters, the optimal catalyst for this reaction is designed.

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Josef Rizell, Doctoral Student, Materials Physics, Physics. The seminar is titled "Lithium metal growth on the nanoscale" Abstract: The energy density of current battery technology severely limits the driving range of electric trucks, cars and airplanes. To improve the energy density of batteries, new electrode materials need to be developed. In theory, one of the most desirable electrode materials to work with is lithium metal. However, batteries using these electrodes typically have short lifetimes, limiting their commercial viability. The root of this problem is that as the battery is charged and discharged, the lithium electrode tends to evolve branched structures with large surface areas. Over time, this leads to loss of electrode material and sometimes even short-circuiting of the battery. To understand the mechanisms through which these detrimental structures develop, and eventually stop them, we study the 3D-structure of lithium metal electrodes using x-ray nanotomography. By tracking how the structures change as the battery is charged and discharged, we correlate battery cycling conditions and the electrode nanostructure.

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Finja Tietjen, Doctoral Student, Condensed Matter and Materials Theory, Physics. The seminar is titled "Ultrafast Entropy Production by Magnons". Abstract: Modern technology demands rapid nanoscale material manipulation, highlighting the need to understand non-equilibrium behavior on fundamental scales. While thermodynamic principles have shaped macroscopic machines, translating them to the (sub)picosecond timescale of material excitations drives the emergent field of ultrafast thermodynamics. This talk shows an example of the successful application of thermodynamics to ultrafast phenomena - the definition of entropy production by magnetic degrees of freedom in pump-probe experiments. In our theoretical approach, we consider a ferromagnet excited by a terahertz laser, which we can describe with the stochastic Langevin equation. Using tools from stochastic thermodynamics, we define entropy production and estimate the heat production by magnetic degrees of freedom. In addition, we simulate the dependency of the magnetization dynamics and therefore entropy production on the pump laser. This allows us to predict and guide experiments and further development of nanotechnology which includes magnetic degrees of freedom.

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Cameron Calcluth, Doctoral Student, Applied Quantum Physics, Microtechnology and Nanoscience. The seminar is titled "Understanding quantum advantage in continuous variable quantum computing" Abstract: Quantum computers are expected to be able to solve certain problems exponentially faster than classical computers. This ability is called quantum advantage. Understanding the properties that lead to quantum advantage is key to the development of new practical quantum algorithms. Earlier research in this field has focused on understanding quantum advantage using qubit-based (a two-level system) quantum computers. However, for continuous-variable quantum computers much less is known. To investigate this, we first developed a method to simulate a restricted class of continuous-variable computations. This lets us understand when these types of quantum computers cannot outperform classical computers. Using this result, we provide a sufficient condition for achieving quantum advantage using continuous variable quantum computing.

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Robin Rydbergh, Project Assistant, Chemistry and Biochemistry, Chemistry and Chemical Engineering. The seminar is titled: "Nanoscale Mass Spectrometry Imaging of Pollution Particles on Cell epithelia" Abstract: Air pollution is a major environmental risk for health, with about 99% of the world's population breathing polluted air, causing 6.8 million early deaths each year (World Health Organization, 2022). In this research project we have looked at how tiny (nano scale) particles from braking trains affect human cells. We created these particles and exposed human cells to them and using an advanced mass spectrometry imaging method, we could see how these particles interact with cell structures. Our new method shows that we could use this approach to study how pollution affects cells, helping future research on how these particles might be toxic. This presentation will highlight the need to understand how pollutants interact with us humans to find ways to better reduce air pollution's health risks.

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Jennifer Gilbert, Postdoc, Chemical Biology, Life Sciences. The seminar is titled "From the Covid vaccine to lactose free milk: How we can use lipid nanoparticles as biomolecule delivery vehicles". Abstract: One of the first things you are taught in chemistry at school is that water and oil don't mix. Some molecules, however, have parts that like water (hydrophilic) and parts that like oil (hydrophobic or 'water hating'), such as the lipids which make up cell membranes in your body. These lipids are called amphiphilic lipids and are composed of a hydrophilic head group and a hydrophobic hydrocarbon tail. When you mix amphiphilic lipids with water, they can form a wide variety of structures, from simple spheres to a 2D sheet (bilayer) and intricate 3D channel networks, depending on the lipid shape and its environment (e.g. temperature and pH). This means that we can make complicated structures with properties, which can be tuned for different applications. One common application in both the food and pharmaceutical industries for these lipid structures is the encapsulation of biomolecules, such as proteins and nucleic acids (like DNA and RNA). As these biomolecules can be quite sensitive, encapsulation can help to keep them more stable. Here I will present two examples, where we have studied biomolecule encapsulation with two different systems: 1) different types of RNA and DNA in a Covid vaccine style formulation and 2) proteins used in the food industry to make different dairy products.
