Space, time, and quantum teleportation of light

Spread the love

From Rebecca Boyle at PopSci.com, we learn, “Researchers Succeed in Quantum Teleportation of Light Waves: Like Schrödinger’s cat, teleported light is both dead and alive” (04.15.2011)

In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.The team employed a mind-boggling set of quantum manipulation techniques to achieve this, including squeezing, photon subtraction, entanglement and homodyne detection. The photo above depicts their device, nicknamed the Teleporter, in the lab of Akira Furusawa at the University of Tokyo.

The results pave the way for high-speed, high-fidelity transmission of information, according to Elanor Huntington, a professor at the University of New South Wales in Australia who was part of the study.

This one looks like it might be true. What are the practical uses?

    This is cool!; Here is a little more background information as to exactly what is going on in telepotation (and entanglement);

    ,,It is interesting to me that one feature of quantum teleportaion only gets mentioned in passing in these articles. That feature is that a photon (or particle) is actually completely destroyed in the experiment. The reason why this destruction of a photon is interesting is that the experiment is a direct controlled violation of the first law of thermodynamics which states that it is impossible to create or destroy energy. And yet in the experiments a photon or particle clearly no longer exists in this physical universe. As well, it is also interesting to note that by destroying a photon by teleporting its ‘infinite’ information to another photon (and completely changing the identity of the other photon in the process) that they also directly show, by default, that ‘infinite transcendent information’ was needed to create, and distinctly specify, each photon in the Big Bang.,, and I know of only one omniscient Being who has been postulated throughout history to possess ‘infinite’ knowledge so as to create the universe.

    How Teleportation Will Work –
    Excerpt: In 1993, the idea of teleportation moved out of the realm of science fiction and into the world of theoretical possibility. It was then that physicist Charles Bennett and a team of researchers at IBM confirmed that quantum teleportation was possible, but only if the original object being teleported was destroyed. — As predicted, the original photon no longer existed once the replica was made.

    Explaining Information Transfer in Quantum Teleportation: Armond Duwell †‡ University of Pittsburgh
    Excerpt: In contrast to a classical bit, the description of a (photon) qubit requires an infinite amount of information. The amount of information is infinite because two real numbers are required in the expansion of the state vector of a two state quantum system (Jozsa 1997, 1) — Concept 2. is used by Bennett, et al. Recall that they infer that since an infinite amount of information is required to specify a (photon) qubit, an infinite amount of information must be transferred to teleport.

    Teleportation has even been extended to atoms;

    Ions have been teleported successfully for the first time by two independent research groups
    Excerpt: In fact, copying isn’t quite the right word for it. In order to reproduce the quantum state of one atom in a second atom, the original has to be destroyed. This is unavoidable – it is enforced by the laws of quantum mechanics, which stipulate that you can’t ‘clone’ a quantum state. In principle, however, the ‘copy’ can be indistinguishable from the original (that was destroyed),,,

    Atom takes a quantum leap – 2009
    Excerpt: Ytterbium ions have been ‘teleported’ over a distance of a metre.,,,
    “What you’re moving is information, not the actual atoms,” says Chris Monroe, from the Joint Quantum Institute at the University of Maryland in College Park and an author of the paper. But as two particles of the same type differ only in their quantum states, the transfer of quantum information is equivalent to moving the first particle to the location of the second.

    Shroud of Turin in 3-D – The Holographic Experience – website
    Abstract – By Dr. Petrus Soons
    This website summarizes work connected with digitizing Shroud photographs taken by Giuseppe Enrie in 1931, enhancing the digitized images to improve details, translating the enhanced images “gray scale data into depth data”, generating a sequence of up to 625 images of each of these, and combining these images with a Holoprinter to produce holograms (3D images) of the Shroud. It also summarizes my study of these holograms and discovery of heretofore unseen details, which confirm many previous findings and reveal some surprises.

    Since God is light, does that mean he travels by quantum teleportation?

    Mung you ask;

    ‘Since God is light, does that mean he travels by quantum teleportation?’

    Light is not ‘traveling’ in quantum teleportation. The ‘infinite’ information needed to specify a single photon is what is ‘instantaneously’ traveling in quantum teleportation. It is an instantaneous action that Einstein called spooky. The action, being ‘instantaneous’, violates what Einstein thought was the universal speed limit of the constant of the speed of light (c = approx. 186,000 miles a second). And though light reveals some of the characteristics of God (eternality of time for one), God created light, thus God transcends even light. i.e. God is not light itself i.e. God is not limited by time or space in any way, shape, or form as light is limited to c!

    And God said, “Let there be light,” and there was light.

    It’s nice to hear that the apostle, inspired by the Holy Spirit, did not intend that his words should be taken literally.
