Jennifer Ahiable, Andreas Winter
We show a simple and systematic way to certify any given bipartite state as the unique joint -eigenstate of two separable projectors, each of which can be measured with simple l…

Generalised Pinching Inequality
Andreas Winter
Hayashi's Pinching Inequality, which establishes a matrix inequality between a semidefinite matrix and a multiple of its "pinched" version via a projective measurement, has found m…
