Protecting sing-photon multi-mode W state from photon loss

Quantum Information Processing, 2014
Single-photon entanglement is of major importance in current quantum communications. However, it is sensitive to photon loss. In this paper, we discuss the protection of single-photon multi-mode W state with noiseless linear amplification.

PHYSICAL STATES AND SCALING PROPERTIES OF W GRAVITIES AND W STRINGS

International Journal of Modern Physics A, 1992
We discuss some physical aspects of W gravities and W strings. We identify global characteristics in W gravities (in addition to the usual Euler characteristic) and show how the dependence of the partition function on the various chemical potentials involves these quantities.

Quantum Teleportation of Tripartite Arbitrary State via W State

Communications in Theoretical Physics, 2005
A scheme of teleportation of a tripartite state via W state is suggested. The W state serves as quantum channels. Standard Bell-state measurements and Von Neumann measurements are performed. After the sender operates the measurements and informs the receiver her results, he can reconstruct the original state by the corresponding unitary transformation.

Probabilistic remote state preparation by W states

Chinese Physics, 2004
In this paper we consider a scheme for probabilistic remote state preparation of a general qubit by using W states. The scheme consists of the sender, Alice and two remote receivers Bob and Carol. Alice performs a projective measurement on her qubit in the basis spanned by the state she wants to prepare and its orthocomplement.

Perfect entanglement swapping of W states

Communications in Theoretical Physics
Abstract In this paper, we propose a perfect entanglement swapping protocol for generating a shared three-qubit W state between two remote parties in a deterministic manner. Our method offers a reliable alternative to existing probabilistic protocols for W state entanglement swapping, which is crucial for various quantum information ...

W(h)ither the State?

2013
Be it in China or India, or any other nation, dictatorship or democracy, everywhere the power of the state is in the ascendant. The citizen is a mere cog, trapped in his minor hankerings even as enormous crimes are committed in his name. Gandhi was suspicious of the state, even a benevolent one, for, as he said, it represented concentrated violence ...
