The authors propose a simple one-sided device-independent scheme for certification of any set genuinely incompatible projective measurements, including mutually unbiased bases, and the maximally entangled state two qudits.

The three-dimensional shapes of thin lamina, such as leaves, flowers, feathers, wings, etc., are driven by the differential strain induced by the relative growth. The growth takes place through variations in the Riemannian metric given on the thin sheet as a function of location in the central plane and also across its thickness. The shape is then a consequence of elastic energy minimization on...
