This proposal will create a microscope for magnetic fields by measuring the quantum spin of a Bose-Einstein condensate at temperatures near absolute zero. Classical measurements of spin have underpinned transforming technologies, from magnetic resonance imaging to terabyte-scale hard-disc storage. We will make a truly quantum measurement of spin which will create a magnetic field microscope one million times more sensitive than the current state-of-the-art. The magnetic field microscope will be sensitive enough to measure fields from single biological cells and from superconducting nanosurfaces, giving critical new perspectives in biomedical research and next-generation electronics.

这一提议将通过在绝对零度附近测量玻色-爱因斯坦凝聚体的量子自旋来创造一个磁场显微镜。对自旋的经典测量支撑了从磁共振成像到TB级硬盘存储的转换技术。我们将对自旋进行真正的量子测量，这将创造出一种比目前最先进的磁场显微镜灵敏度高100万倍的磁场显微镜。磁场显微镜将足够灵敏，可以测量单个生物细胞和超导纳米表面的场，为生物医学研究和下一代电子学提供关键的新视角。
