This award supports the development and construction of a highly advanced cryogenic quantum measurement system. The system will be used to study the frontiers and possible boundaries of quantum mechanics, and will serve a wide range of collaborators (experimental and theoretical), as well as being central to the advanced education of students. The experiments which this system will enable with microfabricated, nanomechanical structures will help to resolve fundamental questions of modern physics, especially those concerning the boundary between the Classical and Quantum regimes, and questions regarding the validity of quantum mechanics for large objects. Furthermore, these developments are expected to impact advanced technologies, particularly those requiring ultra-sensitive mechanical detectors and in the realms of quantum information and computation. To enter and probe this exciting realm of physics, an advanced new system is required which combines a nuclear demagnetization refrigerator accessing 1-10mK temperatures with a heavily engineered electronic environment. The proposed system and resulting research activity will also provide an excellent education to the students and researchers.

该奖项支持高度先进的低温量子测量系统的开发和建设。该系统将用于研究量子力学的前沿和可能的边界，并将服务于广泛的合作者（实验和理论），以及对学生的高等教育的核心。该系统将使微加工、纳米力学结构的实验成为可能，这将有助于解决现代物理学的基本问题，特别是那些关于经典和量子体制之间边界的问题，以及关于量子力学对大物体的有效性的问题。此外，这些发展预计将影响先进技术，特别是那些需要超灵敏机械探测器和量子信息和计算领域的技术。为了进入和探索这个令人兴奋的物理领域，需要一个先进的新系统，它将核消磁冰箱与高度工程化的电子环境结合在一起，温度可达1-10mK。拟议的系统和由此产生的研究活动也将为学生和研究人员提供良好的教育。
