Digital communication systems utilizing entangled qubits are disclosed. The disclosed systems and component sending devices and receiving devices exploit selective entanglement swapping to transfer an entangled state between the sending device and the receiving device. Each device includes pairs of qubits that are independently entangled with pairs of qubits in the other device. By selectively entangling the qubits within a pair in the sending device, the qubits of the corresponding pair in the receiving device also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, systems of the present disclosure determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data. |

It is a common belief today real teleportation of large objects, definitely humans, is science fiction; beyond normal (paranormal). The problem with this assessment (even though promoted among noted scientists) teleportation is happening in front of our eyes today. The Chinese published proof by means of a scientific experimentation that teleportation is real as suggested in a USAF Teleportation Report in 2004. Knowledge to teleport was provided by Nikola Tesla 107 years ago and the science to teleport provided by Albert Einstein and Theodor Kaluza 86 years ago. With today's technology it is time to bring real teleportation into reality. It is time to teleport it is time to add another non-physical aspect into our technology, a non-physical intelligence capable of communicating through Einstein's 4th dimension and providing a foundation for a new world of real teleportation. Teleportation that is attainable in using a precisely tuned octahedron crystal in resonance along with, associated amplification devices and information technology to provide the capability to transfer physical objects, with all their non-physical attributes to predetermined destinations instantaneously. Michio Kuku, a popular theoretical physicist, commented teleportation will probably happen in some future decade or maybe in a century using entanglement; it being a physics ‘engineered solution’. This patent disagrees, real teleportation is not a physics solution, and instead it is an information technology solution. Information Technology today is already using a paranormal (software) means to achieve its objectives, adding another paranormal apparatus provides real teleportation to its list of achievements, therefore making teleporting a reality today, not decades or centuries later. As Tesla stated over a hundred years ago, our world is much more than just physical. |
