Remotely Controlled Entanglement Generation

We consider a system of multiple qubits without any quantum control. show that one can mediate entanglement between different subsystems in controlled way by adding (locally) auxiliary the same size couples via an always-on, distant dependent interaction to qubits. Solely changing internal state control system, selectively couple it selected qubits, and ultimately generate kinds within system. This provides alternative for gates does not rely on ability switch interactions off at will, serve as locally where all patterns be created. demonstrate such approach also offers increased error tolerance w.r.t. position fluctuations.
