Based on the concepts arising from the mathematical discipline of topology, topological materials promise to realize new states of matter with exotic, but robust properties. They also provide a support system to encode information non-locally in ‘topological quantum bits’ robust to local perturbations. The emerging ‘topological quantum computation’ is as such an envisioned solution to decoherence problems in the realization of quantum computers. The implementation of such topological quantum bits remains however an experimental challenge. It relies on highly engineered nanodevices adequately combining topological phases, superconductivity and magnetism. The planned dilution refrigerator system is an essential tool for the developments of topological devices, and in particular quantum bits. The planned major instrument will be used for cooling down samples of topological devices combining high-quality topological insulators and superconductors at ultra-low temperature. The system will then allow for the measurements of these samples in strong magnetic fields, and in all directions of space (vector magnet). The objectives are to identify, trigger, control and manipulate topological excitations in robust topological phases of matter, such as the quantum anomalous effect.

基于拓扑的数学学科产生的概念，拓扑材料有望以异国情调但强大的特性实现物质的新状态。他们还提供了一个支持系统，以“拓扑量子位”对局部扰动的“拓扑量子位”中非局部编码。新兴的“拓扑量子计算”就是这样在实现量子计算机实现中的破坏性问题的设想解决方案。但是，这种拓扑量子位的实施仍然是一个实验挑战。它依赖于高度工程的纳米版，适当地结合了拓扑阶段，超导性和磁性。计划的稀释冰箱系统是拓扑设备（尤其是量子位）开发的重要工具。计划的主要仪器将用于冷却在超低温度下结合高质量拓扑绝缘子和超导体的拓扑设备样品。然后，该系统将允许在强磁场和空间的所有方向（向量磁铁）中测量这些样品。这些目标是识别，触发，控制和操纵物质拓扑阶段（例如量子异常效应）中的拓扑兴奋。
