The RXX gate implements . The Mølmer–Sørensen gate, the native gate on ion-trap systems, can be expressed as a sum of RXX gates.

Note about q-sphere representations
rxx(angle) q[0], q[1];
The q-sphere representation shows the state after the gate operates on the initial equal superposition state where is the number of qubits needed to support the gate.
In IBM Quantum Composer, the default value for angle is .
