中微子振荡中的纠缠

Entanglement in neutrino oscillations

Massimo Blasone, Fabio Dell'Anno, Silvio De Siena, Fabrizio Illuminati

摘要:

基本粒子物理中的味振荡与单粒子态的多模纠缠有关。我们表明,模式纠缠可以表示在味跃迁概率,因此,单粒子纠缠态获得一个精确的操作特性的背景下,粒子混合。我们详细讨论了两味和三味中微子振荡的物理相关的情况,包括CP破坏的有效措施。我们讨论了将单中微子态编码的量子信息转移到空间离域的双味荷电轻子态的实验方案,从而表明,至少在原则上,中微子混合的单粒子纠缠态是量子信息任务的合理物理资源。

英文摘要:

Flavor oscillations in elementary particle physics are related to multi-mode entanglement of single-particle states. We show that mode entanglement can be expressed in terms of flavor transition probabilities, and therefore that single-particle entangled states acquire a precise operational characterization in the context of particle mixing. We treat in detail the physically relevant cases of two- and three-flavor neutrino oscillations, including the effective measure of CP violation. We discuss experimental schemes for the transfer of the quantum information encoded in single-neutrino states to spatially delocalized two-flavor charged lepton states, thus showing, at least in principle, that single-particle entangled states of neutrino mixing are legitimate physical resources for quantum information tasks.
