Quantum electronics based on hybrid super/semi-conductor devices

量子信息科学的兴起为物理学、工程学和材料科学的不同研究领域提供了桥梁。这种交叉在混合量子系统的发展中得到了很好的体现，在混合量子系统中，异构的物理系统被组合在一起，以利用它们各自的优势来实现新的功能。新型量子技术的不断发展表明，需要在不同的材料平台之间进行合成。特别是，半导体技术（当今数字时代的基石）与超导系统（迄今为止最先进的量子计算方法）之间的交叉，预计将提高性能并缩短上市时间。该项目将侧重于半导体和超导体系统的杂交，以支持基于自旋的量子存储器，基于微波光子的量子信息总线，和集成量子控制电子学。研究活动将平衡-半导体集成电路（IC）设计和建模，着眼于通过MEMS插入器实现热绝缘-MEMS谐振器的动手洁净室制造，将超导谐振器耦合到半导体自旋的基于材料的策略-深低温下的实验测量在该项目的整个生命周期中，学生将积累实验室实践经验并成为以下方面的专家：- 低温下量子器件的电气特性-高度自动化实验程序的软件开发（基于Python语言）-洁净室环境中的器件设计和制造-基于第一原理的器件和电路建模以及商业软件包（例如TCAD、CADENCE、AWR微波办公室、Comsol Multiphysics）

The rise of quantum information science has provided bridges between different research areas in physics, engineering and material science. Such a crossover is well embodied by the development of hybrid quantum systems, where heterogeneous physical systems are combined to leverage their individual strengths for the implementation of novel functionalities. The ongoing development of novel quantum technology is showing the need for a synthesis between different material platforms. In particular, a crossover between semiconductor technology, the cornerstone of today's digital age, and superconductor systems, the most advanced approach to date to quantum computing, is anticipated to deliver heightened performance and shortened time to market. This project will focus on the hybridization of semiconductor and superconductor systems to support the development of spin-based quantum memories, microwave photon-based quantum information busses, and integrated quantum control electronics.The research activities will balance - semiconductor integrated circuit (IC) design and modelling with an eye to attaining thermal insulation via superconductive interposers - hands-on cleanroom fabrication of superconductive resonators- material-based strategies for coupling superconductive resonators to semiconductor spins- experimental measurements at deep cryogenic temperaturesThroughout the lifespan of this project, the student will develop hands-on laboratory experience and become an expert of:- electrical characterisation of quantum devices at cryogenic temperature- software development for highly automated experimental routines (based on Python language)- device design and fabrication in cleanroom environment- device and circuit modelling based on first principles as well as commercial software packages (e.g. TCAD, CADENCE, AWR Microwave Office, Comsol Multiphysics)
