论文摘要
已经提出了仅通过重力场相互作用的两个粒子之间的纠缠的实验作为测试是否必须量化重力。用量子信息的语言，非量化引力力将由具有经典通信（LOCC）的本地操作来建模，该操作无法在最初未进入状态下产生纠缠。这个想法被批评为对量子重力的可能替代方案过于限制。我们为量子力学的de Broglie-bohm公式启发了量子物质的重力相互作用的参数化模型，这导致纠缠导致纠缠，从而对只有量化的重力领域具有此能力的说法提供了明确的反例。
Experiments witnessing the entanglement between two particles interacting only via the gravitational field have been proposed as a test whether gravity must be quantized. In the language of quantum information, a non-quantum gravitational force would be modeled by local operations with classical communication (LOCC), which cannot generate entanglement in an initially unentangled state. This idea is criticized as too constraining on possible alternatives to quantum gravity. We present a parametrized model for the gravitational interaction of quantum matter on a classical spacetime, inspired by the de Broglie-Bohm formulation of quantum mechanics, which results in entanglement and thereby provides an explicit counterexample to the claim that only a quantized gravitational field possesses this capability.
