"Beam me up" is one of the most famous catchphrases from the "Star Trek" series. It’s the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise...
Donuts,math,and superdense teleportation of quantum information
Donuts math superdense teleportation quantum information
2015/6/18
Putting a hole in the center of the donut—a mid-nineteenth-century invention—allows the deep-fried pastry to cook evenly, inside and out. As it turns out, the hole in the center of the donut also hold...
Increasing Average Fidelity by Using Non-Maximally Entangled Resource in Teleportation of Superposed Coherent States
Quantum teleportation Superposed coherent state Entangled coherent state Average Fidelity
2011/8/17
Abstract: We consider the problem of teleporting superposed coherent state using non-maximally entangled coherent state as quantum channel and study the effect of entanglement over quality of teleport...

Teleportation System of Identical Particles
2010/10/18
The teleportation of an unknown polarization state of one of the photons in a system of identical particles has been considered. It has been shown that spatial degrees of freedom, which are various di...

Teleportation two qubit subsystem N-qubit W GHZ state
2010/4/9
In this work we study a state which is a random mixture of a two qubit subsystem of a $N$-qubit W state and GHZ state. We analyze several possibilities like separability criterion (Peres-Horodecki cri...
