• Abstract: A quantum decaying system can reveal its nonclassical behavior by being noninvasively measured. Correlations of weak measurements in the noninvasive limit violate the classical bound for a universal class of systems. The violation is related to the incompatibility between exponential decay and unitary evolution. The phenomenon can be experimentally observed by continuous weak measurements and a large class of observables. The nonclassical nature of such a system allows us to treat it as a potential quantum resource.

• Nonlocal Locking of Observable Quantities: A Faithful Signature of Nonclassical Correlations [0.0]
  We propose a general framework to investigate nonclassical correlations in multipartite quantum states. We unveil an intriguing phenomenon referred to as nonlocal locking of observable quantities', where the value of an observable quantity gets locked in the correlation of a nonclassical state.

• Topological correlation: anyonic states cannot be determined by local operations and classical communication [11.59961756146332]
  How to understand topological entanglement entropy is one of the most concerned problems for physicists. For an anyonic bipartite system, we define an operational measure of topological correlation based on the principle of maximal entropy. This measure provides a more refined classification of correlations in a multipartite system with superselection rules.

• Measurement incompatibility is strictly stronger than disturbance [44.99833362998488]
  Heisenberg argued that measurements irreversibly alter the state of the system on which they are acting, causing an irreducible disturbance on subsequent measurements. This article shows that measurement incompatibility is indeed a sufficient condition for irreversibility of measurement disturbance. However, we exhibit a toy theory, termed the minimal classical theory (MCT), that is a counterexample for the converse implication.

• Quantitative non-classicality of mediated interactions [0.5033155053523042]
  We show that the gain of quantum entanglement between the masses indicates non-classicality of the states of the whole tripartite system. We derive inequalities whose violation indicates non-commutativity and non-decomposability. We give applications of these techniques in two different fields: for detecting non-classicality of gravitational interaction and in bounding the Trotter error in quantum simulations.

  We show how a time-independent, finite-dimensional quantum system can give rise to a linear instability corresponding to that in the classical system. An unstable quantum system has a richer spectrum and a much longer recurrence time than a stable quantum system.

• Experimental assessment of non-classicality in a solid-state spin qutrit [0.0]
  Non-classicality, encapsulated by negative quasiprobabilities, has been shown to underlie metrological and thermodynamical advantages. In this work, we use a nitrogen-vacancy center in diamond to realize the experimental implementation of a weak two-point measurement scheme. We experimentally show work extraction, empowered by non-classicality, beyond the classical case.

• Quantum dynamics under simultaneous and continuous measurement of noncommutative observables [10.450171244806906]
  We consider simultaneous and continuous measurement of two noncommutative observables of a system whose commutator is not necessarily a $c$-number. We find that the unconditioned master equation reduces to the Lindblad form in the continuous limit. We propose a scheme to prepare the state of a two-level system in an external field by feedback control based on the simultaneous, continuous measurement of the two observables.

• Non-locality and entanglement in multi-qubit systems from a unified framework [0.0]
  Non-classical probability is the underlying feature of quantum mechanics. We show that violation of any nonlocality inequality implies violation of classical probability rules, through negative probabilities. We employ parent pseudoprojections to show how any number of linear and nonlinear entanglement witnesses for multiqubit systems can be obtained as violations of classical probability rules.

• Anomalous non-classicality via correlative and entropic Bell inequalities [0.0]
  We find that the violation of the correlative Bell inequality does not entail a violation of the correlative Bell inequality for certain parameter values. This anomaly helps to precisely qualify the type of non-classical resource. We identify the 'exotic' type that gives rise to non-classical resources under all non-equivalent operational party assignments.

• Emergence of classical behavior in the early universe [68.8204255655161]
  Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon. We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space. The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.
