• Authors: Dibya S. Chattopadhyay, Amol Dighe
• Abstract summary: We propose a measure of quantumness in neutrino oscillations, which precisely extracts the interference term in the two-flavor limit. These measures are applicable for long-baseline and reactor neutrino experiments that measure neutrino survival probabilities with negligible matter effects.

• Abstract: The quantum nature of neutrino oscillations would be reflected in the mismatch between the neutrino survival probabilities with and without an intermediate observation. We propose this ``quantum mismatch'' as a measure of quantumness in neutrino oscillations, which precisely extracts the interference term in the two-flavor limit. In the full three-flavor scenario, we provide modified definitions of the Leggett-Garg and quantum mismatch measures. These are applicable for long-baseline and reactor neutrino experiments that measure neutrino survival probabilities with negligible matter effects.

• Quantum Correlations in Neutrino and Neutral Meson Oscillations [0.0]
  We discuss the impact of ideas of open quantum systems and quantum information to various facets of neutrino and neutral meson oscillations. For neutrinos, the correlations are shown to be simple functions of the product of neutrino survival and oscillation probabilities. The quantum correlations in the neutral mesons are seen to be non-trivially different from their stable counterparts.

  We conduct the first analysis of imaginarity quantification in neutrino flavor and spin-flavor oscillations. Our findings reveal that even in the case of two-flavor mixing, these measures of imaginarity are nonzero. We extend our analysis to explore the dynamics of three-flavor neutrino mixing, incorporating the effects of a nonzero CP phase.

• Role of non-gaussian quantum fluctuations in neutrino entanglement [0.0]
  neutrino-neutrino coherent scattering can give rise to nontrivial quantum entanglement among neutrinos. We observe that the entanglement induced by the coupling leads to strong delocalization in phase-space with largely non-Gaussian quantum fluctuations. The link between the neutrino entanglement and quantum fluctuations is illustrated using the one- and two-neutrino entropy.

  We offer an interferometric procedure for phase parameters estimation at the Heisenberg (up to 1/N) and super-Heisenberg scaling levels. The heart of our setup is the novel soliton Josephson Junction (SJJ) system providing the formation of the quantum probe. We illustrate that such states are close to the optimal ones even with moderate losses.
