Quantum Computation in Quantum-Hall Systems

We describe a quantum information processor (quantum computer) based on the hyperfine interactions between the conduction electrons and nuclear spins embedded in a two-dimensional electron system in the quantum-Hall regime. Nuclear spins can be controlled individually by electromagnetic pulses. Their interactions, which are of the spin-exchange type, can be possibly switched on and off pair-wis...

Chiral Currents in Quantum Hall

Physicists at Bielefeld University and the Arctic University of Norway in Tromsø have developed a photonic chip that makes it possible to carry out super-resolution light microscopy, also called 'nanoscopy,' with conventional microscopes. In nanoscopy, the position of single fluorescent molecules can be determined with a precision of just a few nano-meters, that is, to a millionth of a millimet...
