The second part will be more technical (15-20 minutes). Abstract We explore quantum-classical hybrid algorithms able to simulate protein folding and try to predict the size of the quantum computer needed to challenge today's classical algorithms. Protein folding is the process by which a protein molecule acquires its final three-dimensional shape, and the correct shape is crucial for the protein to function properly. Many diseases, such as Alzheimer's and cystic fibrosis, are caused by misfolded proteins, so understanding the process of protein folding could lead to new treatments for these and other diseases. One of the main challenges in simulating protein folding is the vast number of possible folds a protein can take. Finding the optimal fold is a large combinatorial problem involving many atoms' simultaneous movement and interactions. These types of problems are what quantum computers are theorised to be better at than classical computers. There are quantum algorithms today able to fold small proof-of-concept proteins; in the future, these algorithms may speed up the process of simulating protein folding. Though, quantum computers are currently not large and precise enough to challenge classical computations. We ask ourselves what kind of quantum computer we would need to revolutionize protein research. Looking forward to seeing you live or on Zoom!

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Jakub Fojt, PhD student at Condensed Matter and Materials Theory, Department of Physics. Abstract: Metal nanoparticles are particles that are smaller than a few hundred nanometers (a nanometer is one billionth of a meter) and consist of a metal. The electrons inside them are easily made to move resonantly, in a motion that can be compared to sloshing from side to side in the nanoparticle. This motion is called a localized surface plasmon, and is typically created by the absorption of light. For example, it can be used to harvest sunlight and direct it to something useful, such as the catalysis of chemical reactions. In the first part of this talk, I will talk about localized surface plasmons in general and compare them to other resonances in nature. In the second part I will discuss the engineering possibilities when it comes to improving catalysis using this process and open questions in the field. The seminar is divided into two parts, where the first part consists of a pure overview of the field and is held on a generally accessible level (10 min). The second part will be more technical (15-20 minutes).
