44th IFF Spring School

Quantum Information Processing

25 February - 08 March 2013 Jülich, Germany



The IFF Spring School 2013 provides a comprehensive introduction to the important developments in quantum information science. The first lectures will look at the roots of the field, which lie in the foundations of quantum theory, and require us to take a careful look at the nature and meaning of the quantum wave function.  A great conceptual success in the field has been to take the philosophical concept of quantum entanglement and give it a precise, mathematical meaning.  Lectures cover the calculations of distillable entanglement and their relationship to quantum channel capacity, and the use of quantum entanglement as a resource in quantum teleportation, superdense coding, and in quantum cryptography.  Early on in the programme, a survey will be made of the great influence that quantum information theory has had on the course of quantum experimental science, and the outlook and criteria for making progress towards the construction of a quantum computer will be discussed.  Further lectures will follow from experts active in the specialist fields of quantum bits and quantum circuits: in single-spin quantum dots, in graphene, in photonic devices, in topological insulators and other structures which incorporate Majorana fermions, and in superconducting devices.  Other lectures will focus on the latest developments in entanglement theory and their application in the efficient representation and simulation of many-particle quantum systems.  Tours of the Forschungszentrum campus will allow students to visit active laboratories engaged in quantum research, as well as large-scale computing facilities used for many-body simulations.


Topics of the lectures include:

  • The emergence of quantum information theory from quantum mechanics
  • Quantum entanglement and teleportation
  • Quantum Communication, error correction
  • Physical implementation of Quantum Computers
  • Many-body quantum simulation
  • Qubits: semiconductor quantum dots
  • Qubits: Josephson-junction devices
  • Qubits: Trapped ions and quantum simulations
  • Qubits: Majorana fermions   

The IFF Spring School is organized in close collaboration with universities, research institutions, and industry. The school offers around 45 hours of lectures plus discussions, as well as the opportunity to visit the participating institutes at Forschungszentrum Jülich. All lectures will be given in English. Each registered participant will be given a copy of the lecture notes (in English), which contain all the material presented during the school.
