Wei Wang,Tomoaki Yokozeki,Reika Ishijima,Atsushi Wada,Yoko Miyamoto,Mitsuo Takeda,Steen Grüner Hanson +6 more
TL;DR: Experimental results are presented that demonstrate the validity and the performance of the proposed optical vortex metrology with nano-scale resolution.
Journal ArticleDOI
Experimental study of coherence vortices: local properties of phase singularities in a spatial coherence function.
TL;DR: This work reports the first direct and quantitative experimental measurement of a generic coherence vortex, controlled by controlling the irradiance of an extended quasimonochromatic, spatially incoherent source.
Journal ArticleDOI
Experimental investigation of local properties and statistics of optical vortices in random wave fields.
TL;DR: The Berry anisotropy ellipse describing the anisotropic squeezing of phase lines close to vortex cores is observed and the Dennis angular momentum rule for its phase is quantitatively verified.
Journal ArticleDOI
Measuring Qutrit-Qutrit Entanglement of Orbital Angular Momentum States of an Atomic Ensemble and a Photon
TL;DR: The fidelity to the maximally entangled state of Schmidt rank 3 exceeds the threshold 2/3, and this result confirms that the density matrix cannot be decomposed into an ensemble of pure states of SchmidtRank 1 or 2.
Journal ArticleDOI
Entanglement of orbital angular momentum states between an ensemble of cold atoms and a photon
TL;DR: Matsukevich et al. as mentioned in this paper experimentally clarified that in an ensemble of atoms and a photon system, there also exists an entanglement concerned with spatial degrees of freedom, and the generation of higher dimensional entanglements between remote atomic ensemble and an application to condensed matter physics are also discussed.
