Although photons have been the only successfully teleported particles , studies have been extended to cover larger particles to objects to bodies as well. Human teleportation is the main objective underlying all these studies which, at this point of time, seems too far-fetched. However, with the great zeal with which this topic is being studied, researched upon and examined, the day is not far when inanimate objects will be quantum teleported . ---- Reetuparna

The distance factor is the greatest motivator.

In April 2011, experimenters reported that they had demonstrated teleportation of wave packets of light up to a bandwidth of 10 MHz while preserving strongly nonclassical superposition states.

Yes Himanshi I totally agree...even i came across that motivating bit of information.

After going through many articles , this is my observation -

Work in 1998 verified the initial predictions, and the distance of teleportation was increased in August 2004 to 600 meters, using optical fiber. The longest distance yet claimed to be achieved for quantum teleportation is 143 km (89 mi), performed in May 2012, between the two Canary Islands of La Palma and Tenerife off the Atlantic coast of north Africa.

Researchers at the Niels Bohr Institute successfully used quantum teleportation to transmit information between clouds of gas atoms, notable because the clouds of gas are macroscopic atomic ensemble- yet another promising application

According to Ray White, physicists say that they have ''teleported'' quantum information farther than ever before . A team of scientists from Austria, Canada and Germany say they beamed the quantum state of a particle of light from one island to another 89 miles away.

Quantum teleportation relies on the phenomenon of entanglement, through which quantum particles share a fragile, invisible link across space. Two entangled photons, for instance, can have correlated, opposite polarization states — if one photon is vertically polarized, for instance, the other must be horizontally polarized. But, thanks to the intricacies of quantum mechanics, each photon’s specific polarization remains undecided until one of them is measured. At that instant the other photon’s polarization snaps into its opposing orientation, even if many kilometers have come between the entangled pair.

An entangled photon pair serves as the intermediary in the standard teleportation scheme. Say Alice wants to teleport the quantum state of a photon to Bob. First she takes one member of a pair of entangled photons, and Bob takes the other. Then Alice lets her entangled photon interfere with the photon to be teleported and performs a polarization measurement whose outcome depends on the quantum state of both of her particles.

Quantum-mechanical systems have information processing capabilities1,2 that are not possible with classical devices. One example is quantum teleportation3, in which the quantum state of a system is transported from one location to another without moving through the intervening space. But although partial implementations4,5 of quantum teleportation over macroscopic distances have been achieved using optical systems, the final stage of the teleportation procedure — which allows the complete recovery of the original state — was omitted. Here we report an experimental implementation of full quantum teleportation over interatomic distances using liquid-state nuclear magnetic resonance. We achieve teleportation of the quantum state of a carbon nucleus to a hydrogen nucleus in molecules of trichloroethylene, by exploiting natural phase decoherence of the carbon nuclei. Such a teleportation scheme may be used as a subroutine in larger quantum computations, or for quantum communication.

I read the following article from

Quantum teleportation1 is an important ingredient in distributed quantum networks2, and can also serve as an elementary operation in quantum computers3. Teleportation was first demonstrated as a transfer of a quantum state of light onto another light beam4, 5, 6; later developments used optical relays7and demonstrated entanglement swapping for continuous variables8. The teleportation of a quantum state between two single material particles (trapped ions) has now also been achieved9, 10. Here we demonstrate teleportation between objects of a different nature—light and matter, which respectively represent ‘flying’ and ‘stationary’ media. A quantum state encoded in a light pulse is teleported onto a macroscopic object (an atomic ensemble containing 1012 caesium atoms). Deterministic teleportation is achieved for sets of coherent states with mean photon number (n) up to a few hundred. The fidelities are 0.58 ± 0.02 for n= 20 and 0.60 ± 0.02 for n= 5—higher than any classical state transfer can possibly achieve11.

This is my say-

Besides being of fundamental interest, teleportation using a macroscopic atomic ensemble is relevant for the practical implementation of a quantum repeater. An important factor for the implementation of quantum networks is the teleportation distance between transmitter and receiver; this is 0.5metres in the present experiment. As our experiment uses propagating light to achieve the entanglement of light and atoms required for teleportation, the present approach should be scalable to longer distances.

So this is another application.

QUANTUM TELEPORTATION

A Tale of Two Cities

Carlton M. Caves*

Quantum teleportation is a process in which information about a quantum state of an object (rather than the object itself) is transported from one location to another. In his Perspective, Caves discusses results published in the same issue by Furusawa et al. in which the quantum state of a light beam was successfully transported from one place to another. Such experiments are the beginning of information processing capabilities completely unavailable in the non-quantum world.

Teleportation Beams Up a Photon's State - Andrew Watson

Researchers at the University of Innsbruck in Austria have shown that part of the spin orientation of a photon of light can be transferred instantaneously to another photon, irrespective of distance. This work is being called the first experimental demonstration of quantum teleportation--the transfer of a quantum state from one particle to another, first proposed by IBM's Charles Bennett and his collaborators in 1993. Quantum teleportation could have applications in quantum computing, say researchers, such as in constructing stable memories, protecting delicate quantum states, and communicating between quantum computers.\

So the very first application of this phenomenon can be summed up to be duplication of quantum states.
