QUANTUM SYSTEM AND METHOD

A method of performing a quantum gate operation using a quantum system wherein the quantum system comprises two or more neutral atoms, wherein each atom of the two or more neutral atoms is configured to transition between atomic states comprising: a first hyperfine ground state of the atom, a second hyperfine ground state of the atom, a Rydberg state and at least one intermediate excited state, wherein the quantum system further comprises an interaction between the Rydberg states of the two or more neutral atoms, and wherein the method comprises:generating a pulse sequence and providing the generated pulse sequence to the two or more neutral atoms to transition the atoms between said atomic states, wherein the pulse sequence takes into account at least part of the hyperfine structure of the at least one intermediate atomic state.
