Bang-Bang运算的经验确定
Empirical Determination of Bang-Bang Operations
摘要：
强而快的“bang-bang”（BB）脉冲最近被提出作为减少量子系统中的退相干的手段。到目前为止，BB技术的理论分析依赖于模型哈密顿。在这里，我们介绍了一种方法，经验确定所需的BB脉冲，依赖于量子过程断层扫描的设置。以这种方式，实验者可以将他或她的BB脉冲定制到手头的量子系统，而不必假设模型哈密顿量。
英文摘要：
Strong and fast "bang-bang" (BB) pulses have been recently proposed as a means for reducing decoherence in a quantum system. So far theoretical analysis of the BB technique relied on model Hamiltonians. Here we introduce a method for empirically determining the set of required BB pulses, that relies on quantum process tomography. In this manner an experimenter may tailor his or her BB pulses to the quantum system at hand, without having to assume a model Hamiltonian.
