JARA-Institute Quantum Information (PGI-11)

Our institute pursues a diverse set of topics that further our theoretical understanding of electronic systems and devices at nano- and atomic scales, and the application of these small quantum systems to new forms of information processing.

Institute Heads: Prof. Dr. David DiVincenzo, Prof. Dr. Hendrik Bluhm

Blueprint for fault-tolerant qubits

Building a universal quantum computer is a challenging task because of the fragility of quantum bits, or qubits for short. Researchers led by Prof. David DiVincenzo have now proposed a design for a circuit with passive error correction. Such a circuit would already be inherently fault protected and could significantly accelerate the construction of a quantum computer with a large number of qubits.

The unification of quantum theory and general relativity remains one of the most important open issues in fundamental physics. A main problem is that we are missing experimental input at scales where quantum and relativistic effects coexist.
