... cooled the macroscopic oscillator to its ground state using optomechanical interaction [2, 3] and unveiled the hitherto elusive quantum radiation pressure shot noise [4]. These remarkable successes imply that strong non-local quantum correlations first predicted by Einstein, Podolsky and Rosen [5], w ...
Introduction to Quantum Computation
... We can copy all the elements of an orthogonal set of states, but when we extend this operation linearly, no other states will be correctly cloned. For example, we can map ...
