申请资金用于由慕尼黑工业大学(TUM)沃尔特·肖特基研究所(WSI)半导体纳米结构和量子系统教席(SNQS-J.J.Finley教授)执行的高级实验中使用的具有光学通道的无制冷剂稀释冰箱和两轴矢量磁体。SNQS的研究直接集中在量子光学和凝聚态物理的交集上。芬利小组使用定制的光场来准备、探测和控制纳米结构半导体中的离散和多体量子态，并应用先进的纳米结构方法来定制长度为几纳米的光-物质相互作用。目前，该小组由大约50人组成，研究主题广泛地集中在：i.量子纳米材料：利用III-V半导体、钻石和2D材料合成和研究专业材料和新型异质界面。特别是基于III-V纳米线的电子和光子系统，2D异质界面中的邻近电子和磁现象以及层间耦合引起的强关联和量子多体相。II.纳米光子和纳米电子系统：III-V半导体和钻石中的量子自旋系统及其在分布式量子光子技术中的应用。离散的自旋-光子界面，基于测量的量子技术方法和纳米级激光器中的集体现象。3.量子传感和通信的纳米系统：开发特别侧重于在生命科学中的应用的量子传感器和工作在量子极限的超灵敏光子探测器。申请的大型设备将由SNQS小组在每个主要研究领域I、II和III中使用。它将开辟全新的研究方向，专注于研究使用原子薄2D半导体及其异质结构实现的强关联量子系统。它将协同地将正在进行的使用半导体量子系统的研究活动与慕尼黑的超导量子电路研究小组联系起来(例如，在MCQST卓越集群内工作)。最后，它将形成慕尼黑地区不同机构(WSI和ZQE)之间计划中的基于原型测量的光子量子通信链路的一个节点。因此，这是一项关键投资，构成了指导SNQS主席未来十年正在进行的研究战略的关键基础设施。

Funding is requested for a cryogen-free dilution refrigerator with optical access and a two-axis vector magnet to be used in advanced experiments performed by the chair Semiconductor Nanostructures and Quantum Systems (SNQS - Prof. J. J. Finley) at the Walter Schottky Institute (WSI) of Technical University of Munich (TUM). Research at SNQS focuses squarely at the intersection of quantum optics and condensed-matter physics. The Finley group use tailored optical fields to prepare, probe and control discrete and many body quantum states in nanostructured semiconductors and apply advanced nanostructuring methods to tailor light-matter interactions at length scales down to a few nanometers. Currently, the group consists of ca. 50 persons with research themes focusing broadly on:I. Quantum Nanomaterials: synthesis and study of specialised materials and novel heterointerfaces using III-V semiconductors, diamond and 2D-materials. In particular, III-V nanowire based electronic and photonic systems, proximity electronic and magnetic phenomena in 2D-heterointerfaces and emergent strongly correlated and quantum many body phases induced by interlayer couplings.II. Nanophotonic & Nanoelectronic Systems: quantum spin-systems in III-V semiconductors and diamond and their use for distributed quantum photonic technologies. Discrete spin-photon interfaces, measurement based approaches to quantum technologies and collective phenomena in nano-scale lasers.III. Nanosystems for quantum sensing and communication: development of quantum sensors with a particular focus on applications in the life-sciences and ultra-sensitive photon detectors operating at the quantum limit.The applied for piece of large equipment will be used by the SNQS group in each of the major research areas I, II and III. It will open up entirely new directions of research focusing on the study of strongly-correlated quantum systems realised using atomically thin 2D-semiconductors and their heterostructures. It will synergistically link the ongoing research activities using semiconductor based quantum systems with Munich based groups working with superconducting quantum circuits (e.g. working within the MCQST cluster of excellence). Finally, it will form one node of a planned prototypical measurement based photonic quantum communication link between different institutions (WSI and ZQE) in the Munich area. As such, it is a key investment that forms the key piece of infrastructure guiding the ongoing research strategy of the SNQS chair for the next decade to come.
