Quantum magnetometry on the microscale

这项提议将通过测量玻色-爱因斯坦凝聚体在接近绝对零度的温度下的量子自旋来创建磁场显微镜。从磁共振成像到太字节级硬盘存储，经典的自旋测量已经成为转换技术的基础。我们将对自旋进行真正的量子测量，这将创造出比目前最先进的磁场显微镜灵敏一百万倍的磁场显微镜。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磁场，为生物医学研究和下一代电子学提供关键的新视角。

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.
