Proposal for a loophole-free violation of Bell's inequalities with a set of single photons and homodyne measurements

چکیده
We demonstrate that different kinds of mesoscopic quantum states of light can be efficiently generated from a simple iterative scheme. These states exhibit strong non-classical features, and could be of great interest for many applications such as quantum error-correcting codes or fundamental testings. Based on these states, we further propose a protocol allowing a large loophole-free violation of a Clauser–Horne–Shimony–Holt (CHSH)-type Bellʼs inequality with significant losses, thus showing that the quantum properties of some of these states can exhibit a remarkable robustness to losses.

Proposal 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 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 کاملContinuous-variable experiments with optical qubits [5631-11]
We present experimental homodyne tomography of an optical quantum bit represented by a single photon split into two optical modes. The reconstructed four-dimensional density matrix extends over the entire Hilbert space and thus reveals, for the first time, complete information about the dual-rail optical qubit as a state of the electromagnetic field. The experimental data violate the Bell inequ...
متن کاملExperimental violation of a Bell's inequality with ef®cient detection
Local realism is the idea that objects have de®nite properties whether or not they are measured, and that measurements of these properties are not affected by events taking place suf®ciently far away. Einstein, Podolsky and Rosen used these reasonable assumptions to conclude that quantum mechanics is incomplete. Starting in 1965, Bell and others constructed mathematical inequalities whereby exp...
