标题： On the quantum mechanics of entropic forces

摘要： 三十年前有人猜测引力可能源于信息的熵重排。本文提出了一组微观量子模型，详细实现了这一想法。特别是，我们提出了一种简单的机制，即牛顿引力定律可以通过一组量子比特或振子的自由能极值化来产生，而不是通过基本场虚拟量子的交换。我们给出了该构造的局部和非局域版本，并展示了如何利用现有的观测结果和近期实验来区分这些熵模型与普通的微扰量子引力。 显示英文摘要

摘要： It was conjectured thirty years ago that gravity could arise from the entropic re-arrangement of information. In this paper, we offer a set of microscopic quantum models which realize this idea in detail. In particular, we suggest a simple mechanism by which Newton's law of gravity arises from extremization of the free energy of a collection of qubits or oscillators, rather than from the exchange of virtual quanta of a fundamental field. We give both a local and non-local version of the construction, and show how to distinguish a range of these entropic models from ordinary perturbative quantum gravity using existing observations and near-term experiments.
