Indistinguishability in general probabilistic theories
John H. Selby, Victoria J. Wright, Máté Farkas +2
The existence of indistinguishable quantum particles provides an explanation for various physical phenomena we observe in nature. We lay out a path for the study of indistinguishab…
Maximal intrinsic randomness of a quantum state
Shuyang Meng, Fionnuala Curran, Gabriel Senno +4
One of the most counterintuitive aspects of quantum theory is its claim that there is 'intrinsic' randomness in the physical world. Quantum information science has greatly progress…
Security of discrete-modulated continuous-variable quantum key distribution
Stefan Bäuml, Carlos Pascual-García, Victoria Wright +2
Continuous variable quantum key distribution with discrete modulation has the potential to provide information-theoretic security using widely available optical elements and existi…
Contextuality and inductive bias in quantum machine learning
Joseph Bowles, Victoria J Wright, Máté Farkas +2
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 ma…
An invertible map between Bell non-local and contextuality scenarios
Victoria J Wright, Máté Farkas
We present an invertible map between correlations in any bipartite Bell scenario and behaviours in a family of contextuality scenarios. The map takes local, quantum and non-signall…
Intermediate determinism in general probabilistic theories
Victoria J Wright
Quantum theory is indeterministic, but not completely so. When a system is in a pure state there are properties it possesses with certainty, known as actual properties. The actual…
Contextuality in composite systems: the role of entanglement in the Kochen-Specker theorem
Victoria J Wright, Ravi Kunjwal
The Kochen--Specker (KS) theorem reveals the nonclassicality of single quantum systems. In contrast, Bell's theorem and entanglement concern the nonclassicality of composite quantu…
Characterising and bounding the set of quantum behaviours in contextuality scenarios
Anubhav Chaturvedi, Máté Farkas, Victoria J Wright
The predictions of quantum theory resist generalised noncontextual explanations. In addition to the foundational relevance of this fact, the particular extent to which quantum theo…
General Probabilistic Theories with a Gleason-type Theorem
Victoria J Wright, Stefan Weigert
Gleason-type theorems for quantum theory allow one to recover the quantum state space by assuming that (i) states consistently assign probabilities to measurement outcomes and that…
Gleason-type Theorems from Cauchy's Functional Equation
Victoria J Wright, Stefan Weigert
Gleason-type theorems derive the density operator and the Born rule formalism of quantum theory from the measurement postulate, by considering additive functions which assign proba…
A Gleason-type theorem for qubits based on mixtures of projective measurements
Victoria J Wright, Stefan Weigert
We derive Born's rule and the density-operator formalism for quantum systems with Hilbert spaces of dimension two or larger. Our extension of Gleason's theorem only relies upon the…
