自旋链哈密顿层析成像中的初始化过程
Bypassing state initialization in Hamiltonian tomography on spin-chains
摘要:
我们提供了一个广泛的讨论方案的自旋链模型,不需要状态初始化的哈密顿断层扫描[物理。102,187203(2009)]。该方法引起了物理学界对间接获取量子多体系统动力学信息的兴趣,并代表了控制受限量子协议的一个真正实例。
英文摘要:
We provide an extensive discussion on a scheme for Hamiltonian tomography of a spin-chain model that does not require state initialization [Phys. Rev. Lett. 102, 187203 (2009)]. The method has spurred the attention of the physics community interested in indirect acquisition of information on the dynamics of quantum many-body systems and represents a genuine instance of a control-limited quantum protocol.
