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 ...
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 ...
Long-Range Quantum Gates using Dipolar Crystals
(American Physical Society (APS), 2012)
We propose the use of dipolar spin chains to enable long-range quantum logic between distant qubits. In our approach, an effective interaction between remote qubits is achieved by adiabatically following the ground state ...
Reservoir engineering and dynamical phase transitions in optomechanical arrays
(American Physical Society (APS), 2012)
We study the driven-dissipative dynamics of photons interacting with an array of micromechanical membranes in an optical cavity. Periodic membrane driving and phonon creation result in an effective photon-number conserving ...
