A theoretical analysis of recent experiments suggests that a key
feature of a topological quantum computer—the unusual statistics
of quasiparticles in the quantum Hall effect—may finally have
been observed. By exploiting the concept of particle-hole
duality, one can realize a point junction between integer and
fractional quantum Hall phases, which constitutes a crucial
building block towards possible applications of the quantum Hall
effect. The fractional quantum Hall effect, thought to be
special to two dimensions, may also flourish in three, providing
a possible explanation for anomalies observed in certain 3D
materials in high magnetic fields. Physics2, 24 (2009) –
Published March 30, 2009 The surprising prediction that currents
can flow forever in small normal metal rings was confirmed
almost twenty years ago. Highly precise new experiments find
good agreement with theory that was not seen till now. H. A.
