Creation of dicke states in distant qubits using linear optics

Abstract

We propose a method to generate long-lived symmetric Dicke states of distant particles requiring linear optics only. Thereby we grant access to genuine entanglement of any number of qubits via measurement using multifold detection techniques.

Generation of Symmetric Dicke States of Remote Qubits with Linear Optics

C. Thiel, Joachim von Zanthier, Thierry Bastin +2 more

We propose a method for generating all symmetric Dicke states, either in the long-lived internal levels of N massive particles or in the polarization degrees of freedom of photonic qubits, using linear optical tools only. By means of a suitable multiphoton detection technique, erasing Welcher-Weg information, our proposed scheme allows the generation and measurement of an important class of entangled multiqubit states.

Generation and classification of robust remote symmetric Dicke states

Zhu Yan-Wu, Kelin Gao

In this paper, we present an approach to generating arbitrary symmetric Dicke states with distant trapped ions and linear optics. Distant trapped ions can be prepared in the symmetric Dicke states by using two photon-number-resolving detectors and a polarization beam splitter. The atomic symmetric Dicke states are robust against decoherence, for atoms are in a metastable level. We discuss the experimental feasibility of our scheme with current technology. Finally, we discuss the classification of arbitrary n-qubit symmetric Dicke states under statistical local operation and classical communication and prove the existence of [n/2] inequivalent classes of genuine entanglement of n-qubit symmetric Dicke states.

Versatile source of polarization-entangled photons

We propose a method for the generation of a large variety of entangled states, encoded in the polarization degrees of freedom of $N$ photons, within the same experimental setup. Starting with uncorrelated photons, emitted from $N$ arbitrary single-photon sources, and using linear optical tools only, we demonstrate the creation of all symmetric states (e.g., GHZ and $W$ states), as well as all symmetric and nonsymmetric total angular momentum eigenstates of the $N$-qubit compound.
