Realization of the Einstein-Podolsky-Rosen paradox for continuous variables.
The Einstein-Podolsky-Rosen (EPR) paradox is demonstrated experimentally for continuous variables by employing a nondegenerate optical parametric amplifier (NOPA). Such a system is analogous to and under some ideal conditions is in one-to-one correspondence with the original system discussed by EPR. In particular, the quadrature-phase amplitudes for a signal beam are inferred in turn from those...
متن کاملGenuine High-Order Einstein-Podolsky-Rosen Steering.
Einstein-Podolsky-Rosen (EPR) steering demonstrates that two parties share entanglement even if the measurement devices of one party are untrusted. Here, going beyond this bipartite concept, we develop a novel formalism to explore a large class of EPR steering from generic multipartite quantum systems of arbitrarily high dimensionality and degrees of freedom, such as graph states and hyperentan...
متن کاملEntanglement, Einstein-Podolsky-Rosen correlations, Bell nonlocality, and steering
In a recent work Phys. Rev. Lett. 98, 140402 2007 we defined “steering,” a type of quantum nonlocality that is logically distinct from both nonseparability and Bell nonlocality. In the bipartite setting, it hinges on the question of whether Alice can affect Bob’s state at a distance through her choice of measurement. More precisely and operationally, it hinges on the question of whether Alice, ...
متن کاملEinstein-Podolsky-Rosen Correlations in Deuteron Photo- disintegration
Einstein-Podolsky-Rosen correlations have so far been measured only between pairs of photons and between pairs of protons. It is proposed to measure these correlations between the proton and the neutron emerging from the breakup of the deuteron induced by gamma rays near threshold. The feasibility of the experiment is discussed. Polarimeters with substantially higher overall efficiency than the...
متن کاملEinstein-Podolsky-Rosen correlations of ultracold atomic gases.
We demonstrate that collective continuous variables of two species of trapped ultracold bosonic gases can be Einstein-Podolsky-Rosen-correlated (entangled) via inherent interactions between the species. We propose two different schemes for creating these correlations--a dynamical scheme and a static scheme analogous to two-mode squeezing in quantum optics. We quantify the correlations by using ...
