Journal ArticleDOI
Broadband Invisibility by Non-Euclidean Cloaking
TL;DR: Here it is shown that transformation optics of a curved, non-Euclidean space (such as the surface of a virtual sphere) relax these requirements and can lead to invisibility in a broad band of the spectrum.
Journal ArticleDOI
Seeing through chaos in multimode fibres
TL;DR: In this article, the prediction of light propagation up to hundreds of millimetres within straight or even deformed segments of multimode fibres is demonstrated in an endoscope and exceptional resolution and footprint are obtained.
Journal ArticleDOI
An omnidirectional retroreflector based on the transmutation of dielectric singularities
TL;DR: An omnidirectional retroreflector is demonstrated, a device for faithfully reflecting images and for creating high visibility from all directions, that would normally require a dielectric singularity, an infinity in the refractive index in a real metamaterial.
Journal ArticleDOI
Spherical media and geodesic lenses in geometrical optics
Martin Šarbort,Tomáš Tyc +1 more
TL;DR: In this paper, a general approach to solving the problems of inverse scattering in three-dimensional isotropic media with a spherically symmetric refractive index distribution is presented, based on equivalence of the central section of an inhomogeneous medium and corresponding geodesic lens.
Journal ArticleDOI
Continuous-variable quantum-state sharing via quantum disentanglement
Andrew M. Lance,Thomas Symul,Warwick P. Bowen,Warwick P. Bowen,Barry C. Sanders,Tomáš Tyc,Timothy C. Ralph,Ping Koy Lam +7 more
TL;DR: A quantum-state sharing protocol in which a tripartite entangled state is used to encode and distribute a secret state to three players and any two of these players can collaborate to reconstruct the secret state, while individual players obtain no information.
