Is entanglement an exclusive feature of quantum systems, or is it common to all non-
classical theories? And if this is the case, how strong is quantum mechanical entanglement …

In this paper, I try once again to cause some good-natured trouble. The issue remains, when
will we ever stop burdening the taxpayer with conferences devoted to the quantum …

We prove a generalized version of the no-broadcasting theorem, applicable to essentially
any nonclassical finite-dimensional probabilistic model satisfying a no-signaling criterion …

We prove that given any two general probabilistic theories (GPTs) the following are
equivalent:(i) each theory is nonclassical, meaning that neither of their state spaces is a …

The papers making up this volume deal with various aspects of what we may call
operational quantum logic. This subject-lying somewhere at the crossroads of mathematics …

The phenomenon of data hiding, ie the existence of pairs of states of a bipartite system that
are perfectly distinguishable via general entangled measurements yet almost …

Unentangled pure states on a bipartite system are exactly the coherent states with respect to
the group of local transformations. What aspects of the study of entanglement are applicable …

Mathematically, quantum mechanics can be regarded as a non-classical probability calculus
resting upon a non-classical propositional logic. More specifically, in quantum mechanics …

We study a variant of quantum hypothesis testing wherein an additional 'inconclusive'
measurement outcome is added, allowing one to abstain from attempting to discriminate the …

Quantum nonlocality without entanglement (Q-NWE) captures nonlocal behavior of
multipartite product states as they may entail global operation for optimal decoding of the …
