Probing macroscopic realism via Ramsey correlations measurements
A. Asadian, C. Brukner, P. Rabl
We describe a new and experimentally feasible protocol for performing fundamental tests of quantum mechanics with massive objects. In our approach a single two level system is used…
Phonon Cooling and Lasing with Nitrogen-Vacancy Centers in Diamond
K. V. Kepesidis, S. D. Bennett, S. Portolan +2
We investigate the strain-induced coupling between a nitrogen-vacancy impurity and a resonant vibrational mode of a diamond nanoresonator. We show that under near-resonant laser ex…
Superconducting Circuits for Quantum Simulation of Dynamical Gauge Fields
D. Marcos, P. Rabl, E. Rico +1
We describe a superconducting-circuit lattice design for the implementation and simulation of dynamical lattice gauge theories. We illustrate our proposal by analyzing a one-dimens…
Generation of hyper-entangled photon pairs in coupled microcavities
S. Portolan, L. Einkemmer, Z. Vörös +2
We propose and theoretically analyze a new scheme for generating hyper-entangled photon pairs in a system of polaritons in coupled planar microcavities. Starting from a microscopic…
Phonon-induced spin-spin interactions in diamond nanostructures: application to spin squeezing
S. D. Bennett, N. Y. Yao, J. Otterbach +3
We propose and analyze a novel mechanism for long-range spin-spin interactions in diamond nanostructures. The interactions between electronic spins, associated with nitrogen-vacanc…
