We present two methods for optimal entanglement concentration from pure entangled states by local actions only. However a prior knowledge of the Schmidt coefficients is required. The first method is optimally efficient only when a finite ensemble of pure entangled states are available whereas the second method realizes the single pair optimal concentration probability. We also propose an entanglement assisted method which is again optimally efficient even for a single pair. We also discuss… Expand
Optimal entanglement concentration via photonic Faraday rotation in cavity QED
Abstract We propose optimal entanglement concentration protocols (ECPs) for photonic or atomic entanglement via photonic Faraday rotation in cavity QED system. It is shown that with the assistance ofExpand

Estimating losses in an entanglement concentration scheme using the phenomenological operator approach to dissipation in cavity quantum electrodynamics
In a previous paper, we developed a phenomenological-operator technique aiming to simplify the estimate of losses due to dissipation in cavity quantum electrodynamics. In this paper, we apply thatExpand
Protocols and quantum circuits for implementing entanglement concentration in cat state, GHZ-like state and nine families of 4-qubit entangled states
Three entanglement concentration protocols (ECPs) are proposed. The first ECP and a modified version of that are shown to be useful for the creation of maximally entangled cat and GHZ-like statesExpand
Generation and characterization in a laboratory ofC2⊗Cdstates of flying electrons and ions with negative or positive partial transpose possessing free or bound entanglement

Signaling versus distinguishing different preparations of same pure quantum state
Different ensembles of quantum states can have the same average nonpure state. Distinguishing between such constructions, via different mixing procedures of the same nonpure quantum state, is knownExpand

Maximal entanglement concentration for $(n+1)$-qubit states
We propose two schemes for concentration of $(n+1)$-qubit entangled states that can be written in the form of $(\alpha|\varphi_{0}\rangle|0\rangle+\beta|\varphi_{1}\rangle|1\rangle)_{n+1}$ whereExpand
