M. Aidelsburger, M. Lohse, C. Schweizer, M. Atala, J. T. Barreiro, S. Nascimbène, N. R. Cooper, I. Bloch, N. Goldman
Nature Physics 11, 162-166 (2015), published online AOP 3171 (2014)

The quantum Hall effect has led to a deeper understanding of topological (or geometrical) effects in physics and has found generalizations in the spin quantum Hall effect and topological insulators. The plateaux in conductivity in this effect are attributed to the Chern numbers, a topological invariant characterizing the Bloch bands.

While superconducting qubits represent a promising technological platform for quantum computation, a good enough control of the mechanisms of decoherence and dissipation in these systems is still an experimental challenge. In particular, Josephson’s key theoretical prediction that quasiparticle dissipation should vanish in transport through a junction when the phase difference across the junction is π has never been observed.

L. Steffen, Y. Salathe, M. Oppliger, P. Kurpiers, M. Baur, C. Lang, C. Eichler, G. Puebla-Hellmann, A. Fedorov and A. Wallraff.
Nature 500, 319-322 (2013)

Demonstrations of primitive information processing elements with quantum bits (qubits) have been
implemented in many systems, but the requirements for precise quantum control, along with fast classical
feed-forward (conditioning future operations on measurement results) has proved challenging.
