论文摘要
我们证明了运算符的生长和无限温度在多体系统中具有$ n $ spin-$ spin-$ \ frac {1} {2} $自由度的自由度的界限。我们的结果参数改善了先前的边界,并严格限制了何时以及如何包括被困的离子晶体和腔量子电动力学,可以研究量子重力。
We prove bounds on operator growth and infinite temperature out-of-time-ordered correlators in many-body systems with $N$ spin-$\frac{1}{2}$ degrees of freedom which interact via two-body all-to-all interactions. Our results parametrically improve previous bounds, and sharply constrain when and how quantum simulators, including trapped ion crystals and cavity quantum electrodynamics, can study quantum gravity.
