Universal Continuous-Variable State Orthogonalizer and Qubit Generator
Universal Continuous-Variable State Orthogonalizer and Qubit Generator
We experimentally demonstrate a universal strategy for producing a quantum state that is orthogonal to an arbitrary, infinite-dimensional, pure input one, even if only a limited amount of information about the latter is available. Arbitrary coherent superpositions of the two mutually orthogonal states are then produced by a simple change …
