Coherence and Raman Sideband Cooling of a Single Atom in an Optical Tweezer
(American Physical Society, 2013)
We investigate quantum control of a single atom in a tightly focused optical tweezer trap. We show that inevitable spatially varying polarization gives rise to significant internal-state decoherence but that this effect ...
Realization of Coherent Optically Dense Media via Buffer-Gas Cooling
(American Physical Society, 2009)
We demonstrate that buffer-gas cooling combined with laser ablation can be used to create coherent optical media with high optical depth and low Doppler broadening that offers metastable states with low collisional and ...
Efficient All-Optical Switching Using Slow Light within a Hollow Fiber
(American Physical Society, 2009)
We demonstrate a fiber-optical switch that is activated at tiny energies corresponding to a few hundred optical photons per pulse. This is achieved by simultaneously confining both photons and a small lasercooled ensemble ...
Coupling a Single Trapped Atom to a Nanoscale Optical Cavity
(American Association for the Advancement of Science (AAAS), 2013)
Hybrid quantum devices, in which dissimilar quantum systems are combined in order to attain qualities not available with either system alone, may enable far-reaching control in quantum measurement, sensing, and information ...
Free-Standing Mechanical and Photonic Nanostructures in Single-Crystal Diamond
(American Chemical Society (ACS), 2012)
A variety of nanoscale photonic, mechanical, electronic, and optoelectronic devices require scalable thin film fabrication. Typically, the device layer is defined by thin film deposition on a substrate of a different ...
Quantum Interference of Single Photons from Remote Nitrogen-Vacancy Centers in Diamond
(American Physical Society (APS), 2012)
We demonstrate quantum interference between indistinguishable photons emitted by two nitrogen-vacancy (NV) centers in distinct diamond samples separated by two meters. Macroscopic solid immersion lenses are used to enhance ...
Coupling of NV Centers to Photonic Crystal Nanobeams in Diamond
(American Chemical Society (ACS), 2013)
The realization of efficient optical interfaces for solid-state atom-like systems is an important problem in quantum science with potential applications in quantum communications and quantum information processing. We ...
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 ...
Repetitive Readout of a Single Electronic Spin via Quantum Logic with Nuclear Spin Ancillae
(American Association for the Advancement of Science (AAAS), 2009)
Robust measurement of single quantum bits plays a key role in the realization of quantum computation and communication as well as in quantum metrology and sensing. We have implemented a method for the improved readout of ...
Trapping and Manipulation of Isolated Atoms Using Nanoscale Plasmonic Structures
(American Physical Society (APS), 2009)
We propose and analyze a scheme to interface individual neutral atoms with nanoscale solid-state systems. The interface is enabled by optically trapping the atom via the strong near-field generated by a sharp metallic ...
