Abstract: The efficient detection of a single spin is a significant goal of improving the sensitivity of quantum magnetic fields sensors. Recent results show that a specific type of entanglement such as Greenberger-Horne-Zeilinger (GHZ) states can… read more here.

DOI: 10.1103/physrevd.101.044042
Abstract: Here we discuss an effect of gravitational decoherence due to time dilation on the collective radiation dynamics of atomic system in timed single-photon Dicke states. We show that a photon absorbed by the stationary system… read more here.

DOI: 10.1364/oe.25.002790
Abstract: In 1954, Dicke predicted that a system of quantum emitters confined to a subwavelength volume would produce a superradiant burst. For such a burst to occur, the emitters must be in the special Dicke state… read more here.
