Quantum state discrimination underlies various applications in quantum information
processing tasks. It essentially describes the distinguishability of quantum systems in …

It is a fundamental consequence of the superposition principle for quantum states that there
must exist nonorthogonal states, that is, states that, although different, have a nonzero …

After a general introduction, the thesis is divided into four parts. In the first, we discuss the
task of coin tossing, principally in order to highlight the effect different physical theories have …

In quantum information processing and quantum computing protocols the carrier of
information is a quantum system and information is encoded in the state of a quantum …

We consider the problem of designing an optimal quantum detector to minimize the
probability of a detection error when distinguishing among a collection of quantum states …

We consider the problem of unambiguous discrimination between a set of linearly
independent pure quantum states. We show that the design of the optimal measurement that …

This paper is concerned with all tests for continuous-variable entanglement that arise from
linear combinations of second moments or variances of canonical coordinates, as they are …

The problem of discriminating among given nonorthogonal quantum states is underlying
many of the schemes that have been suggested for quantum communication and quantum …

This paper presents a comprehensive exploration of semi-definite programming (SDP)
techniques within the context of quantum information. It examines the mathematical …

We propose a generalized discrimination scheme for mixed quantum states. In the present
scenario we allow for certain fixed fraction of inconclusive results and we maximize the …
