Description
Radioactive nuclear decay products are entangled at their creation. Electron capture decays contain just two final state particles: an electron neutrino and a nucleus. Properties of the escaping neutrinos can therefore be determined through measurements of the entangled nuclei. The BeEST experiment implants beryllium-7 directly into superconducting tunnel junctions. After electron capture, the recoil energy of the lithium-7 is measured with unprecedented precision. This measurement is used to place the first direct limits on the size of neutrino wavepackets and paves the way for future tests of quantum mechanics using this novel technique.
