# Towards solving open problems in quantum field theory: from tensor networks to quantum computing

#### Towards solving open problems in quantum field theory: from tensor networks to quantum computing

- Event time: 2:00pm
- Event date: 7th October 2019
- Speaker: Karl Jansen (DESY)
- Location: Higgs Centre Seminar Room, Room 4305, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

There are several problems in quantum field theory which cannot be solved by conventional Monte Carlo simulation techniques, i.e. a non-zero baryon density, the matter-antimatter asymmetry of the universe and real time simulations.

At the example of 1+1 dimensional benchmark models we will discuss new directions towards overcoming these problems. In particular, we will introduce tensor network techniques which are very successful in low dimensions. As another new direction, we will demonstrate that quantum computing could be a practical way in the future to evaluate these problems through variational quantum simulations.

### About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
