Genetic Discrimination: Overview of the Issue and Proposed Legislation
[Excerpt] A key policy issue before Congress is whether the potential for genetic discrimination by employers and insurers merits protections for genetic information that are more extensive than those already in place for health information. For the stated purpose of prohibiting discrimination on the basis of genetic information with respect to health insurance and employment, the Genetic Information Nondiscrimination Act of 2007 (H.R. 493) was introduced in the House on January 16, 2007. On January 22, 2007, the act was introduced in the Senate (S. 358). The act is identical to the Genetic Information Nondiscrimination Act of 2005, which passed the Senate by a vote of 98-0 (S. 306, 109th). An identical House bill (H.R. 1227, 109th), never came to a vote. S. 306 was very similar to S. 1053 (108th), which the Senate passed in 2003 by a vote of 95-0. A distinct House bill, H.R. 1910 (108th), never came to a vote. This report focuses on the key points in the ongoing debate about genetic discrimination legislation
Contextual, Optimal and Universal Realization of the Quantum Cloning Machine and of the NOT gate
A simultaneous realization of the Universal Optimal Quantum Cloning Machine
(UOQCM) and of the Universal-NOT gate by a quantum injected optical parametric
amplification (QIOPA), is reported. The two processes, forbidden in their exact
form for fundamental quantum limitations, are found universal and optimal, and
the measured fidelity F<1 is found close to the limit values evaluated by
quantum theory. This work may enlighten the yet little explored
interconnections of fundamental axiomatic properties within the deep structure
of quantum mechanics.Comment: 10 pages, 2 figure
Modern ‘live’ football: moving from the panoptican gaze to the performative, virtual and carnivalesque
Drawing on Redhead's discussion of Baudrillard as a theorist of hyperreality, the paper considers the different ways in which the mediatized ‘live’ football spectacle is often modelled on the ‘live’ however eventually usurps the ‘live’ forms position in the cultural economy, thus beginning to replicate the mediatized ‘live’. The blurring of the ‘live’ and ‘real’ through an accelerated mediatization of football allows the formation of an imagined community mobilized by the working class whilst mediated through the sanitization, selling of ‘events’ and the middle classing of football, through the re-encoding of sporting spaces and strategic decision-making about broadcasting. A culture of pub supporting then allows potential for working-class supporters to remove themselves from the panoptican gazing systems of late modern hyperreal football stadia and into carnivalesque performative spaces, which in many cases are hyperreal and simulated themselves
Classification of local realistic theories
Recently, it has shown that an explicit local realistic model for the values
of a correlation function, given in a two-setting Bell experiment (two-setting
model), works only for the specific set of settings in the given experiment,
but cannot construct a local realistic model for the values of a correlation
function, given in a {\it continuous-infinite} settings Bell experiment
(infinite-setting model), even though there exist two-setting models for all
directions in space. Hence, two-setting model does not have the property which
infinite-setting model has. Here, we show that an explicit two-setting model
cannot construct a local realistic model for the values of a correlation
function, given in a {\it only discrete-three} settings Bell experiment
(three-setting model), even though there exist two-setting models for the three
measurement directions chosen in the given three-setting experiment. Hence,
two-setting model does not have the property which three-setting model has.Comment: To appear in Journal of Physics A: Mathematical and Theoretica
Hyperentangled States
We investigate a new class of entangled states, which we call
'hyperentangled',that have EPR correlations identical to those in the vacuum
state of a relativistic quantum field. We show that whenever hyperentangled
states exist in any quantum theory, they are dense in its state space. We also
give prescriptions for constructing hyperentangled states that involve an
arbitrarily large collection of systems.Comment: 23 pages, LaTeX, Submitted to Physical Review
Randomness, Nonlocality and information in entagled correlations
It is shown that the Einstein, Podolsky and Rosen (EPR) correlations for
arbitrary spin-s and the Greenberger, Horne and Zeilinger (GHZ) correlations
for three particles can be described by nonlocal joint and conditional quantum
probabilities. The nonlocality of these probabilities makes the Bell's
inequalities void. A description that exhibits the relation between the
randomness and the nonlocality of entangled correlations is introduced.
Entangled EPR and GHZ correlations are studied using the Gibbs-Shannon entropy.
The nonlocal character of the EPR correlations is tested using the information
Bell's inequalities. Relations between the randomness, the nonlocality and the
entropic information for the EPR and the GHZ correlations are established and
discussed.Comment: 19 pages, REVTEX, 8 figures included in the uuencoded postscript fil
Proposed direct test of a certain type of noncontextuality in quantum mechanics
The noncontextuality of quantum mechanics can be directly tested by measuring
two entangled particles with more than two outcomes per particle. The two
associated contexts are "interlinked" by common observables.Comment: 9 pages 2 figure
On relativistic elements of reality
Several arguments have been proposed some years ago, attempting to prove the
impossibility of defining Lorentz-invariant elements of reality. I find that a
sufficient condition for the existence of elements of reality, introduced in
these proofs, seems to be used also as a necessary condition. I argue that
Lorentz-invariant elements of reality can be defined but, as Vaidman pointed
out, they won't satisfy the so-called product rule. In so doing I obtain
algebraic constraints on elements of reality associated with a maximal set of
commuting Hermitian operators.Comment: Clarifications, reference added; published versio
