Physicists say that quantum uncertainty gives rise to entanglement, the putative source of the arrow of time. The idea that entanglement might explain the arrow of time was proposed by Seth Lloyd in the 1980s. Lloyd argues that quantum uncertainty, and the way it spreads as particles become increasingly entangled, could replace human uncertainty in the old classical proofs as the true source of the arrow of time. According to Lloyd, "The arrow of time is an arrow of increasing correlations."

物理学家说量子不确定性引起的纠缠是假定的时间之箭的来源。纠缠可能解释时间之箭的想法是由赛思·劳埃德在20世纪80年代提出的。劳埃德认为,量子不确定性,以及它随着粒子变得越来越纠缠而扩散的方式,可以取代古老的经典证明中人类的不确定性,成为时间之箭的真正来源。按照劳埃德的说法,“时间之箭是一个增加相关性的箭头。”
