Heralded interconversion between hyperentangled W state and hyperentangled KLM state assisted by nitrogen vacancy centers coupled with microresonators by Fang-Fang Du, Ming Ma, Qiu-lin Tan

“…Here we realize completely mutual conversions between spatial-polarization hyperentangled Knill-Laflamme-Milburn state and hyperentangled W state for three-photon systems, resorting to hyperparallel quantum control gates and the practical nonlinear interaction of nitrogen-vacancy centers coupled with whispering-gallery-mode microresonators. …”

Magnetic field characterization of edge currents in quantum spin Hall insulators by Felipe A Pinto, Ricardo C Heitzer, Eitan Dvorquez, Roberto Rodriguez, Qiang Sun, Andrew D Greentree, Brant C Gibson, Jerónimo R Maze

“…In this work, we calculate the magnetic field in the vicinity of the edge and explore the potential role of nitrogen-vacancy centers in diamond as local probes for the characterization of QSH edge states in topological insulators. …”
