Usually, when talking about quantum teleportation, he is referring to the transfer of quantum states of a particle to another without a physical link. Now, physicists have investigated a slightly different form of teleport, which teleports a quantum field, or a full beam from one place to another. It takes such teleportation "strong" for some applications of quantum information, and could lead to quantum teleportation of images.
a plan is proposed to teleport a beam of light, including fluctuations in time. They hope to demonstrate that it is possible that a physical object in one place may arise elsewhere in the same quantum state, so any type of measurement would produce the same result in both places.
In its proposal, the scientists investigated a uniformly spaced stream of photons, or ungrouped. If single photons are detected in a flow that are spaced similarly to the photon flux at the entrance, that would verify the complete quantum teleportation field. The scientists wanted to find the conditions under which this detection could occur. They found that light-compression technique used to improve the accuracy of measurements, could enable quantum teleportation of a quantum flux of photons, if the compression is performed in a wide bandwidth.
Scientists note that the compression levels are challenging, but new research in the design of experiments could reveal more optimal methods. One of the biggest challenges for the realization of this proposal is the requirement for flexible sources of squeezed light quality. If physicists can overcome these challenges, the ability to carry light beams could lead to many interesting applications. For example, researchers suggest that utilza could be a multi-channel version, in which two parallel teleport or more beams, to teleport quantum images.
What is more important, it is likely that the teleportation of light beams offer undiscovered potential and this will bring a breakthrough for science
