Producing GHZ state of nitrogen-vacancy centers in cavity QED
Zheng‐Yuan Xue, Sheng Liu · Journal of Modern Optics · 2013
We propose a scheme to generate the GHZ state of nitrogen-vacancy centers coupled to a whispering-gallery mode cavity. The implemented evolution is independent of the cavity field state with the assistance of a strong classical field, and thus not sensitive to the thermal state of the cavity. Meanwhile, it is fast compared to the convectional dispersive interaction induced operation in a cavity-assisted system. The scheme is readily scalable to the multiqubit scenario.
