The goal of this project is to determine the ability of time-dependent control to engineer nonlinear dynamics in, and nonlinear probes for, mesoscopic quantum resonators. To achieve this the techniques of optimal control theory will be used to obtain control protocols for the purpose of engineering nonlinearities in, and nonlinear interactions with, nano-mechanical and superconducting resonators. The possibility of implementing a SWAP operation between a resonator and a register of superconducting qubits will also be investigated. The above protocols have applications in quantum-state preparation, information processing and metrology. The time-scales required by these protocols, and their robustness properties in the presence of noise, will be investigated. Optimal control theory will also be employed to search for protocols with desired robustness properties.The broader impact of this award includes undergraduate involvement in research and student training in high-performance computing. The project includes support for a summer studentship for an undergraduate to contribute to the research of the project in the second two years. UMass is the most diverse campus in New England, with a large fraction of minorities. The project will therefore provide research opportunities to this diverse group. The research will involve high performance computing and will thus provide training in this area for both graduate and undergraduate students.

这个项目的目标是确定依赖于时间的控制的能力，工程师的非线性动力学，和非线性探针，介观量子谐振器。为了实现这一目标，最优控制理论的技术将被用来获得控制协议的目的工程非线性，和非线性相互作用，纳米机械和超导谐振器。也将研究在谐振器和超导量子位寄存器之间实现SWAP操作的可能性。上述协议在量子态制备、信息处理和计量学中具有应用。将研究这些协议所需的时间尺度，以及它们在噪声存在下的鲁棒性。最优控制理论也将用于搜索具有所需鲁棒性的协议。该奖项的更广泛影响包括本科生参与高性能计算的研究和学生培训。该项目包括为一名本科生提供暑期奖学金，以便在第二个两年为该项目的研究做出贡献。马萨诸塞大学是新英格兰最多样化的校园，少数民族占很大比例。因此，该项目将为这个多样化的群体提供研究机会。这项研究将涉及高性能计算，因此将为研究生和本科生提供这方面的培训。
