Entanglement between an electron and a nuclear spin 1/2
arXiv:quant-ph/0209137 · doi:10.1103/PhysRevLett.90.153001
Abstract
We report on the preparation and detection of entangled states between an electron spin 1/2 and a nuclear spin 1/2 in a molecular single crystal. These were created by applying pulses at ESR (9.5 GHz) and NMR (28 MHz) frequencies. Entanglement was detected by using a special entanglement detector sequence based on a unitary back transformation including phase rotation.
