非微扰k-体到两体的交换转换哈密顿量和Ising自旋的嵌入问题实例

Non-perturbative k-body to two-body commuting conversion Hamiltonians and embedding problem instances into Ising spins

J. D. Biamonte

摘要:

本文提出了一种代数方法,它允许设计包括相互作用自旋系统的低能子空间在内的几个能级。通过引入辅助量子比特,这种方法允许使用2体哈密顿量精确地捕获k体相互作用。当哈密顿量中的所有项共享相同的基并且不依赖于微扰理论或相关的大谱隙时,我们的方法有效。我们的方法允许问题实例的解决方案被嵌入到伊辛自旋系统的基态能量状态。然后,绝热演化可能被用来将一个计算系统置于它的基态。

英文摘要:

An algebraic method has been developed which allows one to engineer several energy levels including the low-energy subspace of interacting spin systems. By introducing ancillary qubits, this approach allows k-body interactions to be captured exactly using 2-body Hamiltonians. Our method works when all terms in the Hamiltonian share the same basis and has no dependence on perturbation theory or the associated large spectral gap. Our methods allow problem instance solutions to be embedded into the ground energy state of Ising spin systems. Adiabatic evolution might then be used to place a computational system into it's ground state.
