Description

The Jülich Supercomputing Centre will host the summer school on Quantum Information Processing – Applications on Gate-based an Annealing Systems” from August 28 to September 01, 2023. 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 a poster session where attendees present their research activities to each other.

Topics: Introduction to gate-based quantum computing, introduction to quantum annealing, formulating QUBO problems, Ising Hamiltonians, Variational Quantum Eigensolvers, Quantum Approximate Optimization Algorithm, simulation of quantum systems, classical vs quantum optimization

Participants have to present a poster. Please submit an abstract for your poster 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 2023". Your application will only be reviewed if abstract, motivation letter 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.

      Introduction to quantum annealing

      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 using quantum annealers

      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.

      Developing a theory of macroscopic resonant tunneling of flux in a double-well potential in the presence of realistic flux noise - a pen & paper excercise

      Superconducting qubits based on different forms of quantum dynamics of magnetic flux in SQUIDs continue demonstrating steady progress. Nevertheless, the low-frequency flux noise in SQUID structures remains the major obstacle to their further development to the level necessary for quantum computing applications. Because of this noise, quantum coherence is essentially reduced to the states with the same qubit value of either 0 or 1 (characterized by the same average value of flux). Only minimal coherence exists between states 0 and 1. We will develop a theory of macroscopic resonant tunneling of flux in a double-well potential in the presence of realistic flux noise with a significant low-frequency component.

      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?
