Quantum phases of condensed matter, such as superconductors and topological insulators, are promising candidates to serve as substrates for quantum information processing. Superconducting quantum interference devices (SQUIDs) already encode qubits and can be coupled together and manipulated. There are exciting recent proposals to use modes at the edges of quantum Hall systems and Majorana modes at the ends of quantum wires to encode and manipulate quantum information. These latter modes would enjoy "topological protection", being robust to local disorder or decoherence.

The goal of this school/workshop is to introduce researchers in the subfields of condensed matter and quantum information to this expanding area of common interest, with the hope of sparking new ideas and collaborations. We will bring together two distinct communities: condensed matter researchers who wish to learn the basics of quantum computation, and researchers in quantum information who want learn what types of condensed matter systems are suitable substrates for quantum information processing, and how ideas such as entanglement, qubits, and unitary gates are actually implemented in them.

We will have a set of courses to educate each community in the other's specialty, interspersed with research talks to emphasize the intertwining of concepts from both fields used in cutting edge research.


  1. Abstract foundations of quantum information. Information and entropy, reversible computation, quantum parallelism, unitary gates and universal quantum computation.
  2. Quantum Hall effects, chiral edge states, fractional charges, Abelian fractional quantum Hall states.
  3. Algorithms in quantum computation and cryptography.
  4. Basics of superconductivity, order parameter, Jopsephson effects, superconducting quantum interference. 
  5. Non-abelian anyons and parafermions in fractional quantum Hall states.   

Eligibility criteria: Applicants should present evidence of interest and a track record in quantum information and/or condensed matter.

Accommodation will be provided for outstation participants at our on campus guest house.

ICTS is committed to building an environment that is inclusive, non-discriminatory, and welcoming of diverse individuals. We especially encourage the participation of women and other under-represented groups.
