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之间架起了桥梁。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，不同的物理系统被结合起来，以利用它们各自的优势来实现新的功能。新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，半导体技术是当今数字时代的基石，超导系统是迄今为止量子计算最先进的方法，两者之间的交叉预计将带来更高的性能和更短的上市时间。这个项目将集中于半导体和超导系统的混合，以支持基于自旋的量子存储器、基于微波光子的量子信息母线和集成量子控制电子的发展。研究活动将平衡半导体集成电路(IC)的设计和建模，着眼于通过超导插入器获得热绝缘-超导谐振器的动手净室制造-超导谐振器与半导体自旋的耦合基于材料的策略-在深低温下的实验测量。贯穿该项目的整个生命周期，学生将发展动手实验室经验，并成为以下方面的专家：-低温下量子设备的电学特性-用于高度自动化实验程序的软件开发(基于Python语言)-洁净室环境中的设备设计和制造-基于第一原理的设备和电路建模以及商业软件包(例如TCAD、Cadence、AWR微波办公室、COMSOL多物理)

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)
