Claim:
1. A quantum information processor comprising: a first processor node that includes a first plurality of qubits and a first actuator, the first plurality of qubits being coupled to the first actuator by respective intra-node quantum couplings in the first processor node; a second processor node that includes a second plurality of qubits and a second actuator, the second plurality of qubits being coupled to the second actuator by respective intra-node quantum couplings in the second processor node, the second actuator being coupled to the first actuator by an inter-node quantum coupling; and a control system operable to manipulate the first plurality of qubits and the second plurality of qubits based on cross-node quantum interactions between the first plurality of qubits and the second plurality of qubits, the cross-node quantum interactions being produced by non-commutivity of the inter-node quantum coupling and each intra-node quantum coupling in the first and second processor nodes; wherein the control system is operable to manipulate a first qubit in the first processor node and a second qubit in the second processor node by applying control operations to the actuators, and the control operations define an interaction frame in which the cross-node quantum interaction between the first qubit and the second qubit dominates the dynamics of the respective first and second qubits; wherein the intra-node quantum coupling H
