致密中微子系统中的多中微子纠缠与关联

Multi-Neutrino Entanglement and Correlations in Dense Neutrino Systems

Marc Illa, Martin J. Savage

AI总结:

本文利用Quantinuum H1-1量子计算机模拟最多12个中微子的集体振荡,通过计算n-tangle及多体关联证明大系统中存在真正的多中微子纠缠。

摘要:

在先前工作的基础上,本文研究了两味集体中微子振荡中多中微子纠缠和关联的时间演化,这与致密中微子环境相关。具体而言,使用Quantinuum的H1-1 20量子比特囚禁离子量子计算机对最多包含12个中微子的系统进行了模拟,用于计算n-tangle以及两体和三体关联,从而探测超越平均场描述的现象。研究发现,对于大系统尺寸,n-tangle的重标度会收敛,这表明存在真正的多中微子纠缠。

英文摘要:

The time-evolution of multi-neutrino entanglement and correlations are studied in two-flavor collective neutrino oscillations, relevant for dense neutrino environments, building upon previous works. Specifically, simulations performed of systems with up to 12 neutrinos using Quantinuum's H1-1 20 qubit trapped-ion quantum computer are used to compute n-tangles, and two- and three-body correlations, probing beyond mean-field descriptions. n-tangle re-scalings are found to converge for large system sizes, signaling the presence of genuine multi-neutrino entanglement.
