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.

Scanning Tunneling Microscopy (STM) can be combined with electron spin resonance. The major advantage of spin resonance is the fact that the energy resolution is independent of the temperature and thus can be much higher than a Fermi-function limited spectroscopy technique such as STM tunneling.
