Black holes have been predicted to radiate particles and eventually evaporate, which has led to the information loss paradox and implies that the fundamental laws of quantum mechanics may be violated. Superstring theory, a consistent theory of quantum gravity, provides a possible solution to the paradox if evaporating black holes can actually be described in terms of standard quantum mechanical systems, as conjectured from the theory. Here, we test this conjecture by calculating the mass of a black hole in the corresponding quantum mechanical system numerically. Our results agree well with the prediction from gravity theory, including the leading quantum gravity correction. Our ability to simulate black holes offers the potential to further explore the yet mysterious nature of quantum gravity through well-established quantum mechanics.
黑洞被预测会辐射粒子并最终蒸发，这导致了信息丢失悖论，并暗示量子力学的基本定律可能被违反。超弦理论是一种一致的量子引力理论，如果像从该理论推测的那样，蒸发的黑洞实际上可以用标准量子力学系统来描述，那么它为该悖论提供了一种可能的解决方案。在这里，我们通过数值计算相应的量子力学系统中的黑洞质量来检验这一推测。我们的结果与引力理论的预测非常吻合，包括主要的量子引力修正。我们模拟黑洞的能力为通过成熟的量子力学进一步探索量子引力的神秘本质提供了潜力。
