Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

A consequence of the quantum mechanical uncertainty principle is that one may not discuss
the path or “trajectory” that a quantum particle takes, because any measurement of position …

Mutually unbiased bases for quantum degrees of freedom are central to all theoretical
investigations and practical exploitations of complementary properties. Much is known about …

A thermal field, which frequently appears in problems of decoherence, provides us with
minimal information about the field. We study the interaction of the thermal field and a …

The concept of coherence is one of cornerstones in physics. The development of quantum
information science has lead to renewed interest in properly approaching the coherence at …

This article presents a general discussion of several aspects of our present understanding of
quantum mechanics. The emphasis is put on the very special correlations that this theory …

We comprehensively review the quantum theory of the polarization properties of light. In
classical optics, these traits are characterized by the Stokes parameters, which can be …

Transfer of entanglement and information is studied for quantum teleportation of an
unknown entangled state through noisy quantum channels. We find that the quantum …

Partial teleportation of entanglement is to teleport one particle of an entangled pair through a
quantum channel. This is conceptually equivalent to quantum swap**. We consider the …
