• Tuesday, August 11, 2020
• 15:29 - 15:30 Session Chair: Karl Jansen 1'
• 15:30 - 15:55 Quantum Technologies at DESY - Brief Introduction 25'  Speaker: Kerstin Borras (DESY)
• 15:55 - 16:30 Quantum-Inspired Optimization based on Digital Annealer 35'
Abstract:
Combinatorial optimization problems thus finding a (global) optimum in a huge search space are one of the most challenging problems in today's industry. Classical computer architectures are typically limited as the problem size increases, Quantum Computers are not there yet to solve real world problems. Â The presentation will outline combinatorial optimization cases in various industries, provide insights on Digital Annealer, a bridge technology to tackle these problems already today, and demonstrate how to represent the problem in a mathematical equation solvable by Digital and Quantum Annealers.

Abstract
A popular approach to machine learning with quantum computers is to interpret the quantum device as a machine learning model that loads input data and produces predictions. By optimizing the quantum circuit, the "quantum model" can be trained like a neural network. This talk highlights different aspects of such "variational quantum machine learning algorithms", including their role in the development of near-term quantum technologies, their close links to kernel methods, and how to get gradients of quantum computations. The practical integration of quantum circuits with machine learning libraries such as PyTorch and Tensorflow is illustrated with the open-source software framework "PennyLane".
