Dissipative phase transition in a central spin system
(American Physical Society (APS), 2012)
We investigate dissipative phase transitions in an open central spin system. In our model the central spin interacts coherently with the surrounding many-particle spin environment and is subject to coherent driving and ...
Suppression of spin-bath dynamics for improved coherence of multi-spin-qubit systems
(Springer Nature, 2012)
Multi-qubit systems are crucial for the advancement and application of quantum science. Such systems require maintaining long coherence times while increasing the number of qubits available for coherent manipulation. For ...
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 ...
Continuous mode cooling and phonon routers for phononic quantum networks
(Institute of Physics, 2012)
We study the implementation of quantum state transfer protocols in phonon networks, where in analogy to optical networks, quantum information is transmitted through propagating phonons in extended mechanical resonator ...
Optomechanical Quantum Information Processing with Photons and Phonons
(American Physical Society, 2012)
We describe how strong resonant interactions in multimode optomechanical systems can be used to induce controlled nonlinear couplings between single photons and phonons. Combined with linear mapping schemes between photons ...
Enhanced solid-state multispin metrology using dynamical decoupling
(American Physical Society (APS), 2012)
We use multipulse dynamical decoupling to increase the coherence lifetime (T2) of large numbers of nitrogen-vacancy (NV) electronic spins in room temperature diamond, thus enabling scalable applications of multispin quantum ...
Efficient photon detection from color centers in a diamond optical waveguide
(American Physical Society (APS), 2012)
A common limitation of experiments using color centers in diamond is the poor photon collection efficiency of microscope objectives due to refraction at the diamond interface. We present a simple and effective technique ...
Nanoplasmonic Lattices for Ultracold Atoms
(American Physical Society (APS), 2012)
We propose to use subwavelength confinement of light associated with the near field of plasmonic systems to create nanoscale optical lattices for ultracold atoms. Our approach combines the unique coherence properties of ...
Coherent, Mechanical Control of a Single Electronic Spin
(American Chemical Society (ACS), 2012)
We demonstrate coherent quantum control of a single spin driven by the motion of a mechanical resonator. The motion of a mechanical resonator is magnetically coupled to the electronic spin of a single nitrogen-vacancy ...
