I have been interested in entanglement as a tool used to build a brain scanner. There are yet some byproducts of that technology. Entanglement is as dimensional multiplication: Before it you have length L and height H, each is one dimensional. After, you have a surface S = L x H. It seems evident that there is more to a surface that to its sides, even if taking into account the properties of infinites with the power of continuum, it can be proved that there is no more points in a surface that there are in a line. In quantum systems, the first use of entanglement is with the qubit concept. A spin 1/2 system can be in the up or down state or an up-down mixing. This allows to represent a bit of information, entanglement produces numbers with more bits. There are too qutrit or quantum ternary information digit and so on. The other big use of entanglement is that when particles P1,P2,...Pn are entangled they cannot be absorbed separately, they work as a single particle with the energy of the sum P1+P2+...+Pn. In another way, entanglement breaks the wave particle duality: The wave is for a single element, such P1 but the particle is for the full set. That is a first look, the reality is even worst: The system is in a superposition of states: one is P1, P2,... all separate from each others, another is P1+P2, the other not included in the entanglement, and so on until all P1+P2+...+Pn are included in the entanglement. The mixing between all these states rests on the properties of the transmission medium. In empty space the medium is linear and each P can be seen as independent. When there is an absorption, the phenomenon is highly non linear and the entanglement is maximum. The published uses are in the microscopy domain, and microelectronics lithography technology. Using plastic lenses, a low density material, an entangled light could work as if there was nearly no entanglement. When hitting a black photosensible resin it could act as an x-ray and produce the corresponding definition. I have pointed before the possibility to use such a radiation to pump an x-ray nuclear laser. Such a laser has many potential uses, from QND brain reading to powerful radiography and time keeping in communication systems, so much informations could be crammed into a given waveband. If a 3 GHz radio generator has a frequency stabilized to 1 kHz, entanglement with exit slit near 10 nm will reduce the relative dispersion by ten millions with two polarization entangled wave, that is, we can separate two channels 100 micro-Hertz away in the gigahertz spectrum. This would produce a capacity limit 10,000 time larger than what is given by simple amplitude modulation. I have pointed out the possibility to use entanglement for "black magic": The basic idea is that a photon P is broken by parametric down conversion into two entangled photons A and B. B is sent to a complex interferometric system putting it in an exotic quantum state. A is then in the same state and exchange its entanglement with a target particle C. C is then in the quantum state defined by the interferometer. Matter could be turned into anything up to Moonshine with that technology. (Don't know the actual price of a bottle of Moonshine yet.) Another possibility: The frozen time. Assume the photon B is broken further into B1 and B2 and these are entangled with some large bunch of photons so that they form a very long wave packet. B1 and B2 have very long life and form a double phase space. This one defines the irreversible time for A. The internal clock of A has slowed down from one tick every one femtosecond or so to one tick every hour or day. If now A is entangled with some particle C, this one will be time frozen for hours or more. For example a muon (heavy electron) can catalyze a fusion reaction but producing it cost more in energy than what it produces in its 2.6 microsecond life. A beam of time frozen muons would burn everything for hours. The ultimate Midas effect. I point out here that this effect is similar to what is found in Special Relativity, even if no high speed is implied. Entanglement of billions of radio wave photons could be used as a rocket effect compressor, the so called Ulam process of nuclear devices. This is out of thermodynamics equilibrium nuclear spin cooling intended to form a Bose-Einstein condensate.There are possibilities to create "long duration" plasmas used in quantum computing and degenerate matter similar to the one found in white dwarf stars for example. Stranger yet: The eversion of fiber bundle states such as SU(2). That would bring in the macroscopic domain the so called "weak force." There are too some "death beams," for example entanglement in the HF domain could "see" biological matter as the vacuum and go throughout as a radio wave. A metal plate behind would be non linear and "collapse the wave function," the result would be a flash of hard x-rays able to vaporize anything. Think about someone in front of a tank, only the tank would be destroyed. More strange yet: The state superposition must extend to very high energy neutrinos. These could start a nuclear reaction and destroy a nuke even behind a concrete wall. The same could be used to turn a nuclear reactor into a prompt chain reaction device, that is, a soft nuclear bomb: It would be "Tchernobylized". An Earth scale SU(2) field would have an energy near 10 megatons, if released at a single point defined by a suitable set of interferences, it could give a good firework. The nuclear x-ray laser pump could be used too as a way to "evaporate" some nuclear elements and produce new nuclear species. Because this system is specific to a given nucleus, it could be used to deactivate radioactive products. It could too form excited nuclear states with fission properties, even if the ground state is not a fissile material, such as lead or bismuth. Using interferometric (holographic) mirrors to produce the entangled states, the virtual exit slit could be reduced to one picometer or one MeV energy on a single polarization. If the starting radiation is one meter radio wave, a second polarization would bring the energy up to one EeV (exa electron volt or one billion billion eV) this is one million times the energy of the most powerful particle accelerator used today, the Tevatron. All of that comes from the linear first quantification, the theory was established by Schrodinger in 1932.
