JUNIQ Summer School on Quantum Computing - Gate-based and Annealing Systems

26 Aug 2024, 08:10 → 30 Aug 2024, 17:00 Europe/Berlin

Building 16.4, room 301 (Forschungszentrum Jülich)

JUNIQ Team

The Jülich Supercomputing Centre will host the summer school on “Quantum Computing – Applications on Gate-based and Annealing Systems” from August 26-30, 2024. The school focuses on hands-on experiences in developing and implementing algorithms on both gate-based devices and quantum annealers. Therefore the attendees will make use of the cloud-programming platform of the Jülich UNified Infrastructure for Quantum computing (JUNIQ) to access quantum devices located at the Jülich Supercomputing Centre. The hands-on sessions will be accompanied by several lectures covering basic concepts of gate-based and annealing systems, the design and implementation of use-cases, and big-picture lectures, all given by experts from the field. The summer school will be complemented by an introductory pitch followed by a poster session where attendees present their research activities to each other.

Topics: Introduction to Gate-Based Quantum Computing, Introduction to Quantum Annealing, Introduction to Quantum Simulation, Formulating QUBO Problems and Ising Hamiltonians, Quantum Approximate Optimization Algorithm, Emulation of Quantum Systems, Classical vs Quantum Optimization.

Participants have to prepare a poster, including a two-minute pitch presentation. Please submit an abstract for your poster, the pitch, and a motivation letter stating why attending this summer school will be beneficial for your current and future research. Submit abstract and motivation letter in one pdf file to training-juniq@fz-juelich.de with the header "Abstract Summer School 2024". In the same e-mail, send the pitch as a separate one-page (corresponding to one slide) pdf file. Your application will only be reviewed if abstract, motivation letter, pitch, and application (follow the "apply now" button) are submitted.

Please note that this is the registration page for on-site participation. In case you want to participate remotely register here.

Important info: given the number of questions regarding the pitch, a short explanation is in order. For the pitch, it is sufficient to merely present your research topic to the audience in a couple of sentences or bullet points. It does not need to be a full summary of your poster or your research.

Registrations closed.

- 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);

10:00 → 11:00 Quantum Simulation

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.

13:00 → 14:00 Simulating Noise of Quantum Computers

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?
