Abstract

We propose linear optical schemes for generating entangled states of two ququarts (four-dimensional quantum systems) in which the single-ququart state is constructed with frequency-nondegenerate biphoton polarization states of spontaneous parametric down-conversion. We show explicitly that it is possible to generate various two-ququart entangled states by interfering two ququarts at a linear optical beam splitter (an ordinary 50-50 beam splitter, a polarizing beam splitter, or a dichroic beam splitter)

Variational study of hard-core bosons in a two-dimensional optical lattice using projected entangled pair states

Journal Article Murg, V. ; Cirac, J. I. ; Verstraete, F. - Physical Review. A

We have studied the system of hard-core bosons on a two-dimensional optical lattice using a variational algorithm based on projected entangled-pair states. We have investigated the ground-state properties of the system as well as the responses of the system to sudden changes in the parameters. We have compared our results to mean-field results based on a Gutzwiller ansatz.

Generating two-photon entangled states in a driven two-atom system

Journal Article Almutairi, Khulud ; Department of Physics, King Saud University, Riyadh 11451 ; Tanas, Ryszard ; ... - Physical Review. A

We describe a mechanism for a controlled generation of a pure Bell state with correlated atoms that involve two or zero excitations. The mechanism inhibits transitions into singly excited collective states of a two-atom system by shifting them from their unperturbed energies. The shift is accomplished by the dipole-dipole interaction between the atoms. The creation of the Bell state is found to be dependent on the relaxation of the atomic excitation. When the relaxation is not present or can be ignored, the state of the system evolves harmonically between a separable to the maximally entangled state. We follow the temporalmore »« less

Simple scheme for generating four-photon polarization-entangled decoherence-free states using spontaneous parametric down-conversions

Journal Article Zou Xubo ; Shu Jing ; Guo Guangcan - Physical Review. A

We propose a simple scheme for the generation of four-photon polarization-entangled decoherence-free states by using a pair of spontaneous parametric down-conversions and one tunable beam splitter. The scheme is based on post-selection strategy and feasible by current experimental technology.

Linear optical implementation of a single-mode quantum filter and generation of multiphoton polarization entangled states

Journal Article Zou Xubo ; Pahlke, K. ; Mathis, W. - Physical Review. A

We propose a scheme to implement a single-mode quantum filter, which selectively eliminates the one-photon state in a quantum state {alpha} vertical bar 0>+{beta} vertical bar 1>+{gamma} vertical bar 2>. The vacuum state and the two-photon state are transmitted without any change. This scheme requires single-photon sources, linear optical elements, and photon detectors. Furthermore, we demonstrate how this filter can be used to realize a two-qubit projective measurement and to generate multiphoton polarization entangled states.

General linear-optical quantum state generation scheme: Applications to maximally path-entangled states

Journal Article VanMeter, N. M. ; Lougovski, P. ; Dowling, Jonathan P. ; ... - Physical Review. A

We introduce schemes for linear-optical quantum state generation. A quantum state generator is a device that prepares a desired quantum state using product inputs from photon sources, linear-optical networks, and postselection using photon counters. We show that this device can be concisely described in terms of polynomial equations and unitary constraints. We illustrate the power of this language by applying the Groebner-basis technique along with the notion of vacuum extensions to solve the problem of how to construct a quantum state generator analytically for any desired state, and use methods of convex optimization to identify bounds to success probabilities.
