A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In
short, it states that quantum mechanics is in conflict with classical models in which the result …

Generalisation in machine learning often relies on the ability to encode structures present in
data into an inductive bias of the model class. To understand the power of quantum machine …

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 …

The concept of antidistinguishability of quantum states has been studied to investigate
foundational questions in quantum mechanics. It is also called quantum state elimination …

In quantum theory, a measurement context is defined by an orthogonal basis in a Hilbert
space, where each basis vector represents a specific measurement outcome. The precise …

Quantum mechanics describes seemingly paradoxical relations between the outcomes of
measurements that cannot be performed jointly. In Hilbert space, the outcomes of such …

The quantum state discrimination problem has Alice sending a quantum state to Bob who
wins if he correctly identifies the state. The pretty good measurement, also known as the …

Quantum state exclusion is an operational task that has significance in studying foundational
questions related to interpreting quantum theory. In such a task, one is given a system …

In this paper, we investigate the possibility of explaining nonclassical correlations between
two quantum systems in terms of quantum interferences between collective states of the two …

Contextuality is a key distinguishing feature between classical and quantum physics. It
expresses a fundamental obstruction to describing quantum theory using classical concepts …
