....2DEG systems can be demonstrated by noise measurement techniques. It exploits the unique properties of Fermidegenerate electrons whichallows the possibility of a regulated source of entangled particles. This is radically dioeerent from previous experiments with massive particles [1619] or photons [6, 7, 20, 21]. Statistics of single particle events are not required. Events are continuously registered and entanglement is veried by noise correlation measurements. This makes possible a new test of Bell s inequality with the closure of the detection loophole. Acknowledgements Wewould like to thank Edo Waks ....

....(3.4) Bob is right with better than chance, if p ok 1 2, which by this computation can be guaranteed as soon as # 2, i.e. as soon as the classical Bell inequality (in Clauser Horne Shimony Holt form [6] is violated. But this is indeed the case in the experiments conducted to determine # (e.g. [11]) which give roughly # # 2 # 2 # 2.8. If we believe these experiments, the only conclusion is that the joint measurability of the B 1 and B 2 used in the experiment would be su#cient to make Bell s Telephone work, which was our claim. 3.4 Entanglement, mixed state analyzers, and correlation ....

....are incorporated into the model. Non locality is introduced into the model via entangled quantum mechanical two particle states. Keywords: 1 Introduction Non locality is a fascinating feature of quantum mechanics ( 13] 4] 5] Non locality was confirmed by a big number of experiments (e.g. [1], 2] 3] 16] These experiments are based on a Bell type inequality (e.g. 4] 10] and the outcomes of the measurements are shown to violate this inequality. Despite the fact that non locality is not the only possible explanation, it is the one which is usually used. We take in this paper also ....

.... EPR paper in 1935 [11] with earlier seeds in the Solvay physics conferences where Einstein debated Bohr via carefully contrived gedanken experiments. Almost seven decades of intense debate, including major theoretical contributions by Bohm [7] and Bell [5] and experimental ones by Aspect [1, 2, 3], have clarified but not resolved the issue in the minds of physicists. Wick [17] is a good informal exposition focusing on historical details of the Bell inequality and Aspect experiments, and Baggott [4] does so with more emphasis on the mathematical formalism. Greenstein and Zajonc [12] focus ....

....of particles detected over all orientations, the function t(OE) t (Eq. 4) I do not take theory i below seriously because of the very large variation in (b) the total particles detected over different orientations, even though it is conceivably consistent with the first Aspect experiment [1]. It is interesting for its tractable and analytical mathematical properties (results can be expressed in closed form) that demonstrate potential implications of these types of theories, and furthermore is very similar to the second theory ii. However for theory ii, as discussed below there is ....
