Robust long-distance entanglement and a loophole-free bell test with ions and photons.
Two trapped ions that are kilometers apart can be entangled by the joint detection of two photons, each coming from one of the ions, in a basis of entangled states. Such a detection is possible with linear optical elements. The use of two-photon interference allows entanglement distribution free of interferometric sensitivity to the path length of the photons. The present method of creating ent...
متن کاملProposal for a loophole-free test of the Bell inequalities.
A proposal for an experimental realization of Bohm s spin-2 particle version of the Einstein-Podolsky-Rosen experiment is described. Two ' Hg atoms, each with nuclear spin 2, are produced in an entangled state with total nuclear spin zero. Such a state is obtained by dissociation of dimers of the ' Hg2 isotopomer using a spectroscopically selective stimulated Raman process. The measurement of n...
متن کاملProposal for a loophole-free Bell test using homodyne detection.
We propose a feasible optical setup allowing for a loophole-free Bell test with efficient homodyne detection. A non-Gaussian entangled state is generated from a two-mode squeezed vacuum by subtracting a single photon from each mode, using beam splitters and standard low-efficiency single-photon detectors. A Bell violation exceeding 1% is achievable with 6 dB squeezed light and a homodyne effici...
متن کاملProposal for a Loophole-Free Bell Test with Electron Spins of Donors in Silicon
So far, all experimental tests of Bell inequalities which must be satisfied by all local realistic hidden-variable theories and are violated by quantum mechanical predictions have left at least one loophole open. We propose a feasible setup allowing for a loophole-free test of the Bell inequalities. Two electron spin qubits of donorsP in a nanoscale silicon host in different cavities 300 m apar...
متن کاملLoophole-free Bell test using electron spins in diamond: second experiment and additional analysis
The recently reported violation of a Bell inequality using entangled electronic spins in diamonds (Hensen et al., Nature 526, 682-686) provided the first loophole-free evidence against local-realist theories of nature. Here we report on data from a second Bell experiment using the same experimental setup with minor modifications. We find a violation of the CHSH-Bell inequality of 2.35 ± 0.18, i...
