论文摘要
我们提出了一个新颖的框架,用于在量子计算机上模拟矩阵模型。超对称矩阵模型具有适当的参数极限,具有自然应用/M理论和重力物理学。此外,对于Berenstein-Maldacena-Nastase(BMN)基质模型中的某些状态,可以在量子设备上实现几种对超弦/M理论双重的超对称量子场理论。我们的处方包括四个步骤:希尔伯特空间的正则化,绝热状态制备,实时动力学的模拟和测量。通过Fock空间中的截断引入能量截止,对BMN矩阵模型进行了正则化。我们使用WAN-KIM算法进行快速的数字绝热状态准备,以准备该模型的低能特征性以及Thermofield双状态。然后,我们提供了一个明确的结构,用于模拟实时动力学,利用块编码,Qubitization和量子信号处理技术。最后,我们提出了一组测量和实验,可以在量子计算机上进行,以进一步了解超边/M理论超出分析结果。
We present a novel framework for simulating matrix models on a quantum computer. Supersymmetric matrix models have natural applications to superstring/M-theory and gravitational physics, in an appropriate limit of parameters. Furthermore, for certain states in the Berenstein-Maldacena-Nastase (BMN) matrix model, several supersymmetric quantum field theories dual to superstring/M-theory can be realized on a quantum device. Our prescription consists of four steps: regularization of the Hilbert space, adiabatic state preparation, simulation of real-time dynamics, and measurements. Regularization is performed for the BMN matrix model with the introduction of energy cut-off via the truncation in the Fock space. We use the Wan-Kim algorithm for fast digital adiabatic state preparation to prepare the low-energy eigenstates of this model as well as thermofield double state. Then, we provide an explicit construction for simulating real-time dynamics utilizing techniques of block-encoding, qubitization, and quantum signal processing. Lastly, we present a set of measurements and experiments that can be carried out on a quantum computer to further our understanding of superstring/M-theory beyond analytic results.
