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 …

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

Towards the end of 2011, Pusey, Barrett and Rudolph derived a theorem that aimed to show
that the quantum state must be ontic (a state of reality) in a broad class of realist approaches …

We apply deep-neural-network-based techniques to quantum state classification and
reconstruction. Our methods demonstrate high classification accuracies and reconstruction …

At the heart of quantum mechanics lies the wave function, a powerful but mysterious
mathematical object which has been a hot topic of debate from its earliest stages. Covering …

Finding quantitative aspects of quantum phenomena which cannot be explained by any
classical model has foundational importance for understanding the boundary between …

Huw Price has proposed an argument that suggests a time symmetric ontology for quantum
theory must necessarily be retrocausal, ie it must involve influences that travel backwards in …

We analyse nonclassical resources in interference phenomena using generalized
noncontextuality inequalities and basis-independent coherence witnesses. We use recently …

One of the most fundamental results in quantum information theory is that no measurement
can perfectly discriminate between nonorthogonal quantum states. In this work, we …

We show that every quantum computation can be described by a probabilistic update of a
probability distribution on a finite phase space. Negativity in a quasiprobability function is not …
