The general problem of performance advantage obtainable by the use of nonclassical transmitted states over classical ones is considered. Attention is focused on the situation where system loss is significant and additive Gaussian noise may be present at the receiver. Under the assumption that the total received state is classical, rigorous output density operator representations and their trace...

A double well loaded with bosonic atoms represents an ideal candidate to simulate some of the most interesting aspects in the phenomenology of thermalisation and equilibration. Here we report an exhaustive analysis of the dynamics and steady state properties of such a system locally in contact with different temperature reservoirs. We show that thermalisation only occurs 'accidentally'. We furt...

Over the past few years, properties of nonclassical states o f light as well as different methods for their production have been widely discussed. In most works, both theoretical and experimental ones, monochromatic continuous-wave pump fields are considered to obtain the nonclassical light, including squeezed states [ 1 ]. Several papers are also devoted to problems of squeezed light pulses [ ...

Detection and threshold-level discrimination of Gabor patches were studied under the conditions of noise masking, in an attempt to isolate 'higher-order' or nonclassical color mechanisms. Detection contours in the equiluminant plane of cone contrast space were measured by varying test chromaticity in the presence of chromatic masking noise. Three equiluminant noise directions were used, in sepa...

Several physiologically important proteins lack a classical secretory signal sequence, yet they are secreted from cells. To investigate the secretion mechanism of such proteins, a representative mammalian protein that is exported by a nonclassical mechanism, galectin-1, has been expressed in yeast. Galectin-1 is exported across the yeast plasma membrane, and this export does not require the cla...

The problem of constructing explicit functions which cannot be approximated by low degree polynomials has been extensively studied in computational complexity, motivated by applications in circuit lower bounds, pseudo-randomness, constructions of Ramsey graphs and locally decodable codes. Still, most of the known lower bounds become trivial for polynomials of superlogarithmic degree. Here, we s...

In this paper, we study a new modified Novikov equation for its classical and nonclassical symmetries and use the symmetries to reduce it to a nonlinear ordinary differential equation (ODE). With the aid of solutions of the nonlinear ODE by using the modified (G′/G)-expansion method proposed recently, multiple exact traveling wave solutions are obtained and the traveling wave solutions are expr...

Since logical knowledge representation is commonly based on nonclassical formalisms like default logic, autoepistemic logic, or circumscript ion, it is necessary to perform abductive reasoning f rom theories of nonclassical logics. In this paper, we investigate how abduction can be performed from theories in default logic. Different modes of abduction are plausible, based on credulous and skept...

Existing measures of bipartite nonclassical correlations that are typically characterized by nonvanishing nonlocalizable information under the zero-way CLOCC protocol are expensive in the computational cost. We define and evaluate economical measures on the basis of a new class of maps, eigenvalue-preserving-but-not-completelyeigenvalue-preserving (EnCE) maps. The class is in analogy to the cla...
