MSGate

class MSGate(num_qubits, theta, *, n_qubits=None, label=None)

Global Mølmer–Sørensen gate.

The Mølmer–Sørensen gate is native to ion-trap systems. The global MS can be applied to multiple ions to entangle multiple qubits simultaneously.

In the two-qubit case, this is equivalent to an XX(theta) interaction, and is thus reduced to the RXXGate.

Create new MS gate.
