Nonclassical States of Cold Atomic Ensembles and of Light Fields
... shown in Fig. 2 as well as for the six fiducial input states, H, V, L, R, S, and T are evaluated from the measured density matrices. Fig. 2 shows that F is close to unity with no notable dependence on the zenith angle θ, and we have verified separately that the same is true for the azimuth angle ϕ. ...

Effective Field Theories, Reductionism and Scientific Explanation
... 2. The Emergence of Effective Field Theories Although the first paper on EFTs appeared only in 1979 (Weinberg, 1979, 1980b), the general idea behind it is much older. As early as in 1936, the German physicists Hans Euler and Werner Heisenberg calculated the process of photon-photon scattering at small ...

The spectral analysis of H requires the determination of the remaining eigenvalues. The physical requirement that the spectrum of H is real imposes important restrictions ...
Quantum Theories of Mind
... experiment with electrons.6 (See figure 14.) The interference effects are not the result of several particles interfering, but occur in the statistical aggregation of single hits, so we may think of quantum events as “guided” by waves. We now know that all elementary particles, atoms and molecules7 ...

A Review and Prospects of Quantum Teleportation
... Quantum teleportation is based on the well-known concept of quantum entanglement. The word “entanglement” was used by Erwin Schrödinger in 1935 in a three-part paper [8]-[11]. Einstein, Podolsky and Rosen prompted these papers in their paper [12] that raised fundamental questions about quantum mecha ...
