We propose a scheme for creating the multidimensional entangled coherent states of two cavity modes in context of cavity quantum electrodynamics(QED). It is pointed out that under certain condition such superposition states can approximate pair coher

We propose a scheme that allow the deterministic remote implementation of a Pauli channel on the state of a distant qubit. The scheme requires two e-bits of entanglements and two classical bits. We also demonstrate that scheme can be extended to high

We show a way to use an optical device set-up to generate the four-particle Greenberger–Horne–Zeilinger (GHZ) state of atoms, which are trapped separately in leaky cavities. Based on cavity decay, photons are transferred from the atom–cavity sy

We present an all-optical scheme to implement the non-deterministic quantum logic operation of Knill, Laflamme and Milburn [Nature 409 (2001) 46–52]. The squeezed vacuum state is used as an auxiliary state. That is why a single-photon source is not

Since quantum systems interact with their environment permanently or within a measurement process, there is much interest in concepts of open quantum system modelling. In this paper we give an overview on three different concepts in order to address

At first we present a scheme to generate the two-photon entangled state |Φ 2 〉= 1 2 (|0〉|0〉|1〉|1〉+|1〉|1〉|0〉|0〉) by single-photon sources, beam splitters and single-photon detectors. Then we demonstrate the generation of multi-photo

A sequence of laser pulses is presented to implement a new kind of CNOT-gate in an linear arrangement of trapped ions. This type of quantum gate enables the designer of quantum algorithms to “send information into the phonon bus” controlled by th

We intend to give an insight into one kind of circuit, the rating of which is based on quantum effects. Therefore, the role of quantum effects is changed from undesired effects to the basic effect of circuit performance. The design of coherent quantu
