HP has definitely not been slacking off in the 3D department, as the photon technology has just received some attention. The Photon technology is not exactly something HP spent a lot of time speaking about, not so far at least. Nonetheless, it is quite possible that it will see more and more attention in the near... |

A gamma-ray detector that can identify the presence of nuclear materials is nothing new these days, so researchers from the University of Michigan thought to do something even more advanced, and they created a detector that can also pinpoint and give the exact location and type of gamma rays. The device is called Po... |

Scientists have discovered boiling hot water vapor in the atmosphere of an aging star, some 500 light-years away from Earth.This discovery contradicts what was generally believed until now - that the chemistry of aging stars would forbid the existence of water vapors within the atmosphere.In the outer atmosphere of t... |

Teleportation defines the relocation of exactly the same item from one initial place to another by using specific technology or paranormal methods. The first mention of the word was in Charles Fort's book “Lo!” from 1931, referring to the connection between the strange occurrence and evanescence of c... |

You can find them mostly anywhere today, they are highly efficient, give off a pleasant white light and, for some strange reasons, people always call them neon lights. Fluorescent lamps produce light by discharging an electrical current inside a mass of gas which becomes excited and starts emitting photon particles o... |

For the first time in history a team of researchers successfully created a system of three entangled diamond nuclei, which they believe to lead to solid state systems that make use of both ions and photons in an entangled state of multiple particles. Entanglement is basically a quantum effect through which the proper... |

Solar cells have the opportunity to revolutionize the electric energy generation process on Earth, but their use today is highly restricted by the high manufacturing costs and their notorious inefficiency in converting light into electricity. The record conversion efficiency for solar cells has been set a couple of w... |

Photon entanglement is believed to be the future of quantum computing, however creating entangled photon pairs is extremely difficult because entangled photons generation is subjected to random quantum processes. This basically means that with a device you can create a single entangled pair while in a later identical... |

The device created by the UK researchers, measuring only a few millimeters across, has the capability to process the signals carried by individual photons of light, much in the same way electronic logic gates control electrical signals. While electronic logic gates may be manufactured into tiny silicon chips and inco... |

You can't transfer much information with a photon, we've learned that from our experience with today's existing optic communication devices. If a single photon of light is manipulated in a classical way, then photons are not too different from electrons in the matter of information transfer, except may... |

Entangled photons are basically particles of light with interlinked properties, meaning that the properties of one photon depend on those of a second photon. The study of the interactions that take place between entangled properties may eventually reveal the fundamental concepts of quantum physics. The National Insti... |

Most of the problems related to lasers nowadays is the so-called photon noise, which determines fluctuations in the laser beam intensity, due to random quantum mechanics interactions, that ultimately reduces the sensitivity of the device. Physicists from the Planck Institute for Gravitational Physics (known as the Al... |

Solid-state light emitting devices have great versatility, as they produce intense light, a great variety of colors, and can use tunable power sources. On the other hand, they share a dirty little secret. The semiconductor nanostructure tends to emit light in pulses, blinking on and off as the lights in a Christmas t... |

The Sun is relatively generous when it comes to providing the Earth with power, as massive amounts of energy are daily radiated towards our planet. It has been calculated that, on a sunny day, the Sun is able to produce about 1,000 watts of pure energy per square meter on the surface of the Earth. If only we were abl... |

Non-locality, says in theory, can't possibly treat separated physical systems as independent. The simplest example of non-locality is a wave. Any object is space must obey the principle of wave-particle duality, therefore all objects in the universe are non-local. Non-locality does not imply the lack of causalit... |

Solar cells use the light of the Sun to produce electric current, through an effect known as the photoelectric effect or the Hertz effect, due to its discovery by Heinrich Rudolf Hertz. It was first explained by Albert Einstein using the wave-particle duality of the light, work which gave Einstein the Nobel Prize for... |

A backward causality experiment is not really intended to explain time travel and its (im)probability, although this might be just a wonderful side-effect. Nonlocal quantum communication could instantly send information millions of light-years away and possibly even back in time.Quantum entanglement is once again ex... |

Qubits are single units of quantum information, based on the fact that quantum states can be interpreted as information, which can be compressed in a state and stored on a smaller number of states. Most researchers seem to think photons will be the next step in computing technology, creating the supercomputers of th... |

Present theories on light explain its nature through the notion of wave-particle duality, that Einstein described in the early 1900s and state that light has both a particle nature and a wave nature. A new theory predicts that light could be made to exhibit properties similar to those of matter, although photons do... |

The subject of invisibility has been obsessing human beings ever since they were able to imagine how it would be like to be unseen by others. Mythology is full of examples: the ring of Gyges is described in a story in Plato's The Republic. A peasant finds a ring in the tomb of a dead king which allows him to b... |

Optoelectronics is the science that studies the electronic devices that interact with light, in fact a subfield of photonics, that deals with light in both the visible and the invisible spectrum (gamma rays, X-rays, ultraviolet and infrared). It is based on the quantum mechanical effects of light on semiconducting ... |

Pions are some of matter's simplest particles. Built from the same building blocks as protons and neutrons, pions come in three types, designated by electric charge (positive, negative and chargeless). In particle physics, pion is the collective name for three subatomic particles. Pions are the lightest mesons ... |

In modern physics, the photon is the elementary particle responsible for electromagnetic phenomena. It mediates electromagnetic interactions and makes up all forms of light. The photon has zero invariant mass and travels at the constant speed "c", the speed of light in empty space. However, in the presence of matter... |

For 80 years, the scientists have supported Niels Bohr's opinions stating that in any experiment, light shows only one aspect at a time, either a wave or a particle. "Einstein was deeply troubled by that principle, since he could not accept that any external measurement would prevent light to reveal its full dua... |

When a light bulb is turned on, each second 10 to the power of 15 visible photons shed light in the room.
