Far-Field Optical Imaging and Manipulation of Individual Spins with Nanoscale Resolution
(Nature Publishing Group, 2010)
A fundamental limit to existing optical techniques for measurementand manipulation of spin degrees of freedom is set by diffraction, which does not allow spins separated by less than about a quarter of a micrometre to be ...
Photonic Phase Gate via an Exchange of Fermionic Spin Waves in a Spin Chain
(American Physical Society, 2010)
We propose a new protocol for implementing the two-qubit photonic phase gate. In our approach, the pi phase is acquired by mapping two single photons into atomic excitations with fermionic character and exchanging their ...
Fast Entanglement Distribution with Atomic Ensembles and Fluorescent Detection
(American Physical Society, 2010)
Quantum repeaters based on atomic ensemble quantum memories are promising candidates for achieving scalable distribution of entanglement over long distances. Recently, important experimental progress has been made toward ...
Two-orbital SU(N) magnetism with ultracold alkaline-earth atoms
(Nature Publishing Group, 2010)
Fermionic alkaline-earth atoms have unique properties that make them attractive candidates for the realization of atomic clocks and degenerate quantum gases. At the same time, they are attracting considerable theoretical ...
