量子计算机上的超共形量子力学

Superconformal Quantum Mechanics on a Quantum Computer

Yuan Feng, Michael McGuigan, Tristen White

摘要:

在量子计算机上研究了超共形量子力学。我们研究了质量形变的SCQM在量子计算上的基态,使用变分量子本征求解器(VQE),使用一个玻色子和一个玻色子-一个费米子希尔伯特空间,有和没有噪音,并比较结果的准确性。在Trotter-Suzuki近似下,利用量子计算机上的演化哈密顿(EOH)算法研究了SCQM的Feynman路径积分,并与精确结果进行了比较.我们考虑一个N玻色子和N费米子版本的SCQM,给出了超对称Calogero-Moser-Sutherland(SCMS)模型。我们比较了用VQE计算得到的SCMS理论的基态与精确解。最后,我们讨论了在量子计算机上数值模拟SCQM对反德西特/超共形场论(AdS/CFT)对应的量子引力模拟的意义.

英文摘要:

We investigate superconformal quantum mechanics (SCQM) on a quantum computer. We study the ground state of the mass deformed SCQM on a quantum computed using the Variational Quantum Eigensolver (VQE) using a one boson and one boson - one fermion Hilbert space with and without noise and compare the accuracy of the results. We study the Feynman path integral for SCQM using the Evolution of Hamiltonian (EOH) algorithm on the quantum computer using the Trotter-Suzuki approximation and compare with the exact result. We consider an N boson and N fermion version of SCQM given be the Supersymmetric Calogero-Moser-Sutherland (SCMS) model. We compare the ground state of SCMS theory obtained using the VQE computation with the exact solution. Finally we discuss the implications of the the numerical simulation of SCQM on a quantum computer for the simulation of quantum gravity in light of the Anti-de Sitter/Superconformal field theory (AdS/CFT) correspondence.
