A CNOT-gate implementation for information transfer by the phonon bus

K. Pahlke, L. Kroneberg, Wolfgang M. Mathis

A scheme of quantum state manipulation is presented to implement a new kind of CNOT-gate in a two stored ion arrangement. This type of quantum gate enables the designer of quantum algorithms to "send information into the phonon bus" controlled by the information stored in one of the ions. Some simulation results are given to show the dynamics of the system during the step by step implementation.

Multiparticle entanglement with quantum logic networks: Application to cold trapped ions

Marek Šašura, Vladimír Bužek

We show how to construct a multiqubit control gate on a quantum register of an arbitrary size N. This gate performs a single-qubit operation on a specific qubit conditioned by the state of other $N\ensuremath{-}1$ qubits. We provide an algorithm how to build up an array of networks consisting of single-qubit rotations and multiqubit control-NOT (CNOT) gates for the synthesis of an arbitrary entangled quantum state of N qubits. We illustrate the algorithm on a system of cold trapped ions. This example illuminates the efficiency of the direct implementation of the multiqubit CNOT gate compared to its decomposition into a network of two-qubit CNOT gates.

Remote controlled-NOT gate of d-dimension

Gui-Fang Dang, Heng Fan

Single qubit rotation gate and the controlled-NOT (CNOT) gate constitute a complete set of gates for universal quantum computation. In general the CNOT gate are only for two nearby qubits. For two qubits which are remote from each other, we need a series of swap gates to transfer these two qubits to the nearest neighboring sites, and then after the CNOT gate we should transfer them to their original sites again. However, a series of swap gates are resource for quantum information processing. One economy way which does not consume so much resource is to implement CNOT gate remotely. The remote CNOT gate is to implement the CNOT gate for two remotely separated qubits with the help of one additional maximally entangled state. The original remote CNOT gate is for two qubits, here we will present the d-dimensional remote CNOT gate. The role of quantum teleportation is identified in the process of the remote CNOT gate.
