Sequential discrimination of qudits by multiple observers

Discrimination by Parallel Observers

Discrimination by Parallel Observers: The Algorithm

The main result of the paper is a constructive proof of the following equivalence: two pure -terms are observationally equivalent in the lazy concurrent -calculus i they have the same L evy-Longo trees. An algorithmwhich allows to build a context discriminating any two pure -terms with di erent L evy-Longo trees is described. It follows that contextual equivalence coincides with behavioural equ...

Generation of qudits and entangled qudits

We propose schemes for the generation of d-level quantum states qudits and quantum entangled states of N qudits by adopting the polarization degree of freedom of photons. Arbitrary qudits can be prepared by putting d−1 identical and independent photons each with a given polarization into a single spatial and temporal mode. Then, by using N such qudits, linear optics, and proper projection measu...

Relating color discrimination to photopigment genes in deutan observers

Deutan observers are a heterogeneous group, varying nearly continuously from deuteranomalous trichromats with fine chromatic discrimination in the red/green range to deuteranopes who have none. We sought to relate chromatic discriminative ability among deutans measured psychophysically (phenotypes) to observers' separation between long-wave visual pigments inferred from visual pigment genes (ge...

A Sequential Theory of Psychological Discrimination*

A theory of discrimination which assumes that subjects compare psychological values evoked by a stimulus to a subjective referent is proposed. Momentary differences between psychological values for the stimuh~s and the referent are accumulated over time until one or the other of two r~sponse thresholds is first exceeded. The theory is analyzed as a random walk bounded between two absorbing barr...
