Resonance fluorescence localization microscopy with sub-wavelength resolution
(United States. Patent and Trademark Office, 2015-11-10)
The resonance fluorescence spectrum of a number of two-level atoms is driven by a gradient coherent laser field. In the weak dipole-dipole interaction region (separation less than λ/50), a very strong laser field may be ...
Protecting quantum entanglement from amplitude damping in a two qubit system
(United States. Patent and Trademark Office, 2015-04-14)
Preservation of quantum entanglement in a two-qubit system is achieved by use of the disclosed systems. Three different example two-qubit systems are shown: (1) a system employing a weak measurement, (2) a system in which ...
