Abstract: The precision with which we can measure operators that do not commute with conserved quantities is limited by the need to preserve the associated global symmetries. We show how to construct a local hidden-variable model that violates Bell inequalities by interpreting this measurement error as altering the measure space of the hidden variables. This provides a physically-motivated example of a supermeasured model, where the statistical independence assumption used to form Bell inequalities is violated without there being a causal dependence of the measurement settings on the hidden variables (superdeterminism) or a causal dependence of the hidden variables on the measurement settings (retrocausality). The model also gives subtly different predictions to quantum mechanics, that could be tested experimentally.

Enhanced Entanglement in the Measurement-Altered Quantum Ising Chain [43.80709028066351]
Local quantum measurements do not simply disentangle degrees of freedom, but may actually strengthen the entanglement in the system.<n>This paper explores how a finite density of local measurement modifies a given state's entanglement structure.

Measurement dependence in a Bell inequality arising from the dynamics of hidden variables [0.0]
Bell inequalities rely on an assumption that the probabilities of adopting configurations of hidden variables describing a system prior to measurement are independent of the choice of measured physical property.<n>We explore various models of the dynamics of the hidden variables under measurement, revealing features that can create measurement dependence and others that can not.

Nonparametric Identifiability of Causal Representations from Unknown Interventions [63.1354734978244]
We study causal representation learning, the task of inferring latent causal variables and their causal relations from mixtures of the variables. Our goal is to identify both the ground truth latents and their causal graph up to a set of ambiguities which we show to be irresolvable from interventional data.

Evolution of many-body systems under ancilla quantum measurements [58.720142291102135]
We study the concept of implementing quantum measurements by coupling a many-body lattice system to an ancillary degree of freedom. We find evidence of a disentangling-entangling measurement-induced transition as was previously observed in more abstract models.

Full counting statistics as probe of measurement-induced transitions in the quantum Ising chain [62.997667081978825]
We show that local projective measurements induce a modification of the out-of-equilibrium probability distribution function of the local magnetization. In particular we describe how the probability distribution of the former shows different behaviour in the area-law and volume-law regimes.

Trade-off relations between measurement dependence and hidden information for factorizable hidden variable models [0.0]
The Bell theorem is explored in terms of a trade-off relation between underlying assumptions within the hidden variable model framework.<n>We propose a measure termed hidden information' taking account of their distribution.<n>It is also revealed that the relation gives a necessary and sufficient condition for the measures to be realized by a factorizable model.

Relaxed Bell inequalities as a trade-off relation between measurement dependence and hiddenness [0.0]
Quantum correlations that violate the Bell inequality cannot be explained by any (measurement independent) local hidden variable theory. We introduce a quantification of hidden variables (hiddenness) and derive a new trade-off relation between the hiddenness and the measurement dependency.

Supermeasured: Violating Bell-Statistical Independence without violating physical statistical independence [0.0]
Bell's theorem is often said to imply that quantum mechanics violates local causality. This is only correct if the hidden-variables theory fulfils an assumption called Statistical Independence.

Where and What? Examining Interpretable Disentangled Representations [96.32813624341833]
Capturing interpretable variations has long been one of the goals in disentanglement learning. Unlike the independence assumption, interpretability has rarely been exploited to encourage disentanglement in the unsupervised setting. In this paper, we examine the interpretability of disentangled representations by investigating two questions: where to be interpreted and what to be interpreted.
