Introduction to Quantum Annealing

• Madita Willsch

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.

Quantum Simulation

• Jaka Vodeb

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.

Simulating Noise of Quantum Computers

• Kevissen Sellapillay

As much as we want to isolate them, we must see quantum machines as open systems. Interactions happen between the quantum machine and its environment leading to decoherence. This effectively give different types of noise at the level of the machine. What are they and how can we take them into account when doing simulation on our classical computer?
