Introduction to Quantum Annealing

• Madita Willsch (JSC)

Room: Building 16.4, Room 301 (Rotunda) This talk is a general introduction to quantum annealing. It covers: - how does a quantum annealer work in theory and what can it be used for; - what are the theoretical and practical limitations; - how to solve problems on quantum annealers, in particular D-Wave quantum annealers as the one hosted by JSC; - the basic information about the architecture of D-Wave quantum annealers; - how to formulate an optimization problem as a QUBO or Ising problem; - different encoding strategies; - how to incorporate constraints; - how to embed a (logical) problem onto the given hardware graph (considering physical connectivity); - how to send a problem to the quantum annealer using D-Wave's Ocean SDK and how to interpret the response; Finally, some small examples are presented and the talk ends with a short hands-on exercise.

QUBO Formulation and QAOA: A Tutorial on Encoding and Solving Combinatorial Optimization Problems - Part I

• Jhon Alejandro Montanez-Barrera (JSC)

Room: Building 16.4, Room 301 (Rotunda) In this tutorial, we will dive into combinatorial optimization problems and explore how effectively encode these problems using the Quadratic Unconstrained Binary Optimization (QUBO) formulation and how to tackle them using the Quantum Approximate Optimization Algorithm (QAOA).

Introduction of Hands-on Topics Room: Building 16.4, Room 301 (Rotunda) In this session, the topics for the hands-on sessions will be introduced.

Quantum Simulation

• Jaka Vodeb

Room: Building 16.4, Room 301 (Rotunda) I will talk about the first experimental signatures of two-dimensional many-body false vacuum decay in a quantum material emerging from microscopic interactions. We used a programmable noisy superconducting quantum simulator with 2008 qubits in order to perform simulations corresponding to our specific experiment on quantum domain reconfiguration in a topical electronic crystal. We carefully chose a simulator with the same measured noise spectrum to ensure the fidelity of the model correspondence between the two systems, thereby presenting a realization of simulating real-world open quantum systems according to the original vision of Feynman.
