In this note we discuss the effect of the unpolarized state in the spin-correlation measurement of the \(^1S_0\) two-proton state produced in 12C(d,2He) reaction at the KVI, Groningen. We show that ...in the presence of the unpolarized state the maximal violation of the CHSH-Bell inequality is lower than the classical limit if the purity of the state is less than \( \sim \verb+70%+\). In particular, for the KVI experiment the violation of the CHSH-Bell inequality should be corrected by a factor \(\sim\verb+10%+\) from the pure \(^1S_0\) state.
I show that an experimental technique used in nuclear physics may be successfully applied to quantum teleportation (QT) of spin states of massive matter. A new non-local physical effect the ...`quantum-teleportation-effect' is discovered for the nuclear polarization measurement. Enhancement of the neutron polarization is expected in the proposed experiment for QT that discriminates {\it only} one of the Bell states.
We discuss the effect of quantum statistics on the $g_{s}$-factor quenching
in nuclear medium. We have found that the two nucleon correlation function can
be described by a Gaussian with correlation ...length $\sigma\sim1.2$ fm. An
estimate of the M1 quenching strength is given. The effect of quantum
statistics on the retardation of the paramagnetic susceptibility is also
discussed.
We report on the effect of the quantum statistics on the two-proton spin
correlation (SC) in cold and thermal nuclear matter. We have found that two
nucleons SC function can be well approximated by a ...guassian with correlations
length $\sigma\sim1.2$ fm. We have proposed SC measurement on low protons
energy as test of the quark-gluon plasma formation in relativistic heavy ions
collisions.
Acta Phys.Polon. B36 (2005) 801-815 The entanglement at finite temperatures are analyzed by using thermal models
for colored quarks making up the hadron physical states. We have found that
these ...quantum correlations entirely vanish at $T_c\geq m_q/\ln(1.5)$. For
temperatures larger than $T_c$ the correlations are classical. Also we worked
out the entanglement for the transverse Ising spin chain. In dependence on both
temperature $T$ and transverse field $\lambda$ we can identify a certain
region, where the quantum effects are likely to dominate the system. We suggest
the mutual information as a quantitative measure for the correlations in ground
state.
J. Phys. A: Math. Gen. 36 (2003) L387-L391 Distillable entanglement ($E_d$) is one of the acceptable measures of
entanglement of mixed states. Based on discrimination through local operation
and ...classical communication, this paper gives $E_d$ for two classes of
orthogonal multipartite maximally entangled states.
