[Info.aoa-nano] Inställt: Nano Smalltalks "Folding proteins with a quantum computer"

[Nano]

SmallTalks [about Nanoscience]
Please join us at 15.00h for our SmallTalks [about Nanoscience]
You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom: https://chalmers.zoom.us/j/63018620593#success


Our speaker is Hanna Linn, PhD student at the Department of Microtechnology and Nanoscience, Applied Quantum Physics Laboratory and WACQT (Wallenberg Centre for Quantum Technology)


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).
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!
Best regards,
Alexandra, Philippe, Christoph, and Janine
