A new approach to entangling neutral atoms.
Our team has developed a new approach to entangling neutral atoms with a Rydberg - dressed interaction . Entangling neutral atoms is an essential key of quantum technologies such as quantum computation, many - body quantum simulation , and high - precision atomic sensors . The demonstrated Rydberg - dressed protocol involves adiabatically imposing a light shift on the ground state by coupling an excited Rydberg state wit h a tuned laser field. Using this technique, we have demonstrated a strong and tunable dipole - dipole interaction between two individually trapped atoms with energy shifts of order 1 MHz , which has been challenging to achieve in other protocols . During thi s program, we ex perimentally demonstrated Bell - state entanglement and the isomorphism to the Jaynes - Cumming model of a Rydberg - dressed two - atom system . Our theoretical calculations of a CPHASE quantum logic gate and a rbitrary Dicke state quantum control in this system encourage further work.
