容错量子模拟的资源需求:横向伊辛模型基态

Resource Requirements for Fault-Tolerant Quantum Simulation: The Transverse Ising Model Ground State

Craig R. Clark, Kenneth R. Brown, Tzvetan S. Metodi, Samuel D. Gasster

摘要:

我们估计了计算N个自旋为1/2粒子的一维量子横向伊辛模型(TIM)的基态能量所需的资源需求、物理量子比特总数和计算时间,作为系统大小和数值精度的函数。这种估计是基于分析容错量子纠错的量子逻辑阵列(QLA)架构的上下文中的影响。我们的研究结果表明,由于指数缩放的计算时间与所需的精度的能量,显着量的错误correciton是需要实现TIM问题。Shor的量子因子分解算法的容错实现的资源需求的比较表明,所需的逻辑量子比特的可靠性是类似的TIM问题和因子分解问题。

英文摘要:

We estimate the resource requirements, the total number of physical qubits and computational time, required to compute the ground state energy of a 1-D quantum Transverse Ising Model (TIM) of N spin-1/2 particles, as a function of the system size and the numerical precision. This estimate is based on analyzing the impact of fault-tolerant quantum error correction in the context of the Quantum Logic Array (QLA) architecture. Our results show that due to the exponential scaling of the computational time with the desired precision of the energy, significant amount of error correciton is required to implement the TIM problem. Comparison of our results to the resource requirements for a fault-tolerant implementation of Shor's quantum factoring algorithm reveals that the required logical qubit reliability is similar for both the TIM problem and the factoring problem.
