Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster than the speed of light. Bell's theoremâ€¦ (More)

The violation of a Bell inequality is an experimental observation that forces the abandonment of a local realistic viewpointâ€”namely, one in which physical properties are (probabilistically) definedâ€¦ (More)

The quantum internet is predicted to be the next-generation information processing platform, promising secure communication and an exponential speed-up in distributed computation. The distribution ofâ€¦ (More)

As a direct consequence of the no-cloning theorem, the deterministic amplification as in classical communication is impossible for unknown quantum states. This calls for more advanced techniques in aâ€¦ (More)

We report an experimental violation of a Bell inequality with strong statistical significance. Our experiment employs polarization measurements on entangled single photons and closes the locality,â€¦ (More)

Tests of the predictions of quantum mechanics for entangled systems have provided increasing evidence against local realistic theories. However, there remains the crucial challenge of simultaneouslyâ€¦ (More)
