Abstract

I show how to protect adiabatic quantum computation (AQC) against decoherence and certain control errors, using a hybrid methodology involving dynamical decoupling, subsystem and stabilizer codes, and energy gaps. Corresponding error bounds are derived. As an example, I show how to perform decoherence-protected AQC against local noise using at most two-body interactions.

摘要

我展示了如何使用一种混合方法来保护绝热量子计算（AQC）免受退相干和某些控制误差的影响，该方法涉及动态解耦、子系统和稳定器编码以及能隙。推导了相应的误差界限。作为一个例子，我展示了如何使用至多两体相互作用来执行针对局部噪声的退相干保护的AQC。
