Abstract

Reactor experiments are well suited to probe the possible loss of coherence of neutrino oscillations due to wave-packets separation. We discuss how decoherence modifies neutrino oscillation probabilities. We focus on the reactor experiments RENO, Daya Bay and KamLAND and discuss how well these experiments can constrain decoherence effects. We also present expected sensitivities for the future experiment JUNO.

Probing neutrino quantum decoherence at reactor experiments

André de Gouvêa, Valentina De Romeri, Christoph A. Ternes

Abstract We explore how well reactor antineutrino experiments can constrain or measure the loss of quantum coherence in neutrino oscillations. We assume that decoherence effects are encoded in the size of the neutrino wave-packet, σ. We find that the current experiments Daya Bay and the Reactor Experiment for Neutrino Oscillation (RENO) already constrain σ > 1.0×10−4 nm and estimate that future data from the Jiangmen Underground Neutrino Observatory (JUNO) would be sensitive to σ < 2.1 × 10−3 nm. If the effects of loss of coherence are within the sensitivity of JUNO, we expect σ to be measured with good precision. The discovery of nontrivial decoherence effects in JUNO would indicate that our understanding of the coherence of neutrino sources is, at least, incomplete.

Neutrino oscillation bounds on quantum decoherence

Valentina De Romeri, Carlo Giunti A, Thomas Stuttard +1 more

Abstract We consider quantum-decoherence effects in neutrino oscillation data. Working in the open quantum system framework we adopt a phenomenological approach that allows to parameterize the energy dependence of the decoherence effects. We consider several phenomenological models. We analyze data from the reactor experiments RENO, Daya Bay and KamLAND and from the accelerator experiments NOvA, MINOS/MINOS+ and T2K. We obtain updated constraints on the decoherence parameters quantifying the strength of damping effects, which can be as low as Γij ≲ 8 × 10−27 GeV at 90% confidence level in some cases. We also present sensitivities for the future facilities DUNE and JUNO.

Quantifying quantum coherence in experimentally observed neutrino oscillations

Xue‐Ke Song, Yanqi Huang, Jiajie Ling +1 more

Neutrino oscillation represents an intriguing physical phenomenon where the quantumness can be maintained and detected over a long distance. Previously, the nonclassical character of neutrino oscillation was tested with the Leggett-Garg inequality, where a clear violation of the classical bound was observed [J. A. Formaggio et al., Phys. Rev. Lett. 117, 050402 (2016)]. However, there are several limitations in testing neutrino oscillations with the Leggett-Garg inequality. In particular, the degree of violation of the Leggett-Garg inequality cannot be taken as a ``measure of quantumness.'' Here, we focus on quantifying the quantumness of experimentally observed neutrino oscillation, using the tools of the recently developed quantum resource theory. We analyzed ensembles of reactor and accelerator neutrinos at distinct energies from a variety of neutrino sources, including Daya Bay (0.5 and 1.6 km), KamLAND (180 km), MINOS (735 km), and T2K (295 km). The quantumness of the three-flavored neutrino oscillation is characterized within a $3\ensuremath{\sigma}$ range relative to the theoretical prediction. It is found that the maximal coherence was observed in the neutrino source from the KamLAND reactor. However, even though the survival probability of the Daya Bay experiment did not vary significantly (it dropped about 10%), the coherence recorded can reach up to 40% of the maximal value. These results represent the longest distance over which quantumness was experimentally determined for quantum particles other than photons.

Quantum correlations in neutrino oscillations

Massimo Blasone A, Silvio De Siena, Cristina Matrella

We investigate quantum correlations in the context of neutrino oscillations, with specific reference to Daya-Bay and MINOS experiments. We compute the non-local advantage of quantum coherence -- a valuable quantum resource -- for the two experiments, within the wave-packet approach. We find that this kind of non-local correlation may persist at long distances, when oscillations are washed out, depending on the value of the mixing angle.

Wave packet approach to quantum correlations in neutrino oscillations

Massimo Blasone A, Silvio De Siena, Cristina Matrella

Abstract Quantum correlations provide a fertile testing ground for investigating fundamental aspects of quantum physics in various systems, especially in the case of relativistic (elementary) particle systems as neutrinos. In a recent paper, Ming et al. (Eur Phys J C 80:275, 2020), in connection with results of Daya-Bay and MINOS experiments, have studied the quantumness in neutrino oscillations in the framework of plane-wave approximation. We extend their treatment by adopting the wave packet approach that accounts for effects due to localization and decoherence. This leads to a better agreement with experimental results, in particular for the case of MINOS experiment.
