| The Rydberg blockade is of great interest for many quantum information processing schemes, since it provides a way to deterministically entangle two or more atoms and to drive fast quantum gates. Here, we report on the generation of entanglement between two individual 87Rb atoms in hyperfine ground states |F=1,mF=1> and |F=2,mF=2> which are held in two optical tweezers separated by 4 µm. The entangled state is generated in about 200 ns using pulsed two-photon excitation. We quantify the entanglement by applying global Raman rotations on both atoms. |
