Maximal Holevo Quantity Based on Weak Measurements

The Holevo bound is a keystone in many applications of quantum information theory. We propose " maximal Holevo quantity for weak measurements" as the generalization of the maximal Holevo quantity which is defined by the optimal projective measurements. The scenarios that weak measurements is necessary are that only the weak measurements can be performed because for example the system is macrosc...

Aspects of weak interactions

Weak interactions, such as those non-covalent interactions that occur in biological systems, are less well characterised than their strong, covalent counterparts. Here, we discuss associations between two or more molecules and consider the effect of interactions with solvent molecules (particularly water) and changes in the internal structure of the associating molecules on binding. We go on to...

Future of Weak Interactions

I am supposed to speak on the future of weak interactions, which is an impossible task. Aside from the constraint of causality, we cannot even pretend to know the future without knowledge of the past. What will be done is often mere analogy to what was done already, unless we stumble on something truly revolutionary, like quantum mechanics or relativity. The periodic table of Mendele’ev was for...

Weak Interactions Between Molecules

Explicit formulae are derived for the calculation of dispersion energies between large molecules, at various levels of approximmion. The derivation introduces frequency-dependent polarizabilities (FDPs), whiCh describe the propagation of electron density fluctuat· ions within each of the separate molecules, but avoids the usual multipole expansion. The resultant dispersion energy formula reveal...
