Abstract

We describe the underlying concept and experimental demonstration of the basic building blocks of a scalable quantum information processor architecture using trapped ion-qubits. The trap structure is divided into many subregions. In each several ion-qubits can be trapped in complete isolation from all the other ion-qubits in the system. In a particular subregion, ion- qubits can either be stored as memory or subjected to individual rotations or multi-qubit gates. The ion-qubits are guided through the array by appropriately switching control electrode potentials. Excess energy that is gained through the motion of ion-qubits in the array or other heating mechanisms can be removed by sympathetic cooling of the ion-qubits with another ion species. The proposed architecture can be used in a highly parallel fashion, an important prerequisite for fault-tolerant quantum computation.
