Communication scenarios between two parties can be implemented by first encoding
messages into some states of a physical system which acts as the physical medium of the …

We introduce the resource quantifier of weight of resource for convex quantum resource
theories of states and measurements with arbitrary resources. We show that it captures the …

There are various ways to quantify the communication capabilities of a quantum channel. In
this work we introduce the communication value (cv) of quantum channel, which describes …

Oblivious transfer is an important primitive in modern cryptography. Applications include
secure multiparty computation, oblivious sampling, e-voting, and signatures. Information …

A set of n pure quantum states is called antidististinguishable if there exists an n-outcome
measurement that never outputs the outcome 'k'on the k th quantum state. We describe sets …

A set of pure quantum states is said to be antidistinguishable if upon sampling one at
random, there exists a measurement to perfectly determine some state that was not …

A core principle of quantum theory is that nonorthogonal quantum states cannot be perfectly
distinguished with single-shot measurements. However, it is possible to exclude a subset of …

Apart from the Bell nonlocality, which deals with the correlations generated from the local
input-output statistics, quantum theory exhibits another kind of nonlocality that involves the …

We investigate the question which communication tasks can be accomplished within a given
operational theory. The concrete task is to find out which communication matrices have a …

No-broadcasting theorem is one of the most fundamental results in quantum information
theory; it guarantees that the simplest attacks on any quantum protocol, based on …
