Schrödinger's Cat is a famous thought experiment that also represents one of the foundations of quantum mechanics. It was first proposed in 1935, by famed Austrian physicist Erwin Schrödinger. In its current interpretation, it provides the theoretical basis for quantum entanglement and superposition. ... |

A group of investigators from the Princeton University in the United States says that it recently managed to gather more insights into the nature of electrons. They way that scientists did this was by analyzing how single electrons interact with their environment.Using a complex, laser-based study technique, the expe... |

For a long time, experts have been saying that preventing whales from getting entangled in fishing nets is a whole lot more efficient at ensuring the animals' survival than intervening to disentangling them.This idea was again confirmed in Florida recently, when a right whale was observed floating dead in waters... |

A group of investigators recently managed to achieve an important milestone in bringing the quantum computers of tomorrow closer to reality. Physicists in the United Kingdom managed to produce a device that can act as a source of entangled photons. The source can be controlled by the simple passing of an electric cur... |

Entanglement is a property that subatomic, elementary particles have, of being in instant contact with each other over massive distances. For example, if in a quantum system a particle is observed, and therefore has its properties established, the same thing happens to its pair, regardless of where the second one is ... |

Quantum physics is undoubtedly one of the most interesting and well-developed areas of research at this point. The two main abilities that quantum systems exhibit – superposition and entanglement – are currently being investigated by a large number of scientists around the world. However, the experts find... |

Quantum computers are one of the most promising and hard-to-reach goals in the world today. These machines promise unprecedented calculation power, that would make today's supercomputers look like mere pocket calculators. But achieving stable quantum operations is tremendously difficult, and groups around the wo... |

According to a new research conducted by Swedish and Polish experts, photons used for quantum-data transmissions have strength in numbers. They reveal that the elementary particles, which make up quantum bits, or qubits, the basic units of a quantum computer, are much less likely to trigger the scrambling of transmit... |

According to a scientific paper appearing in this issue of the respected scientific journal Nature, experts at the university of California in Santa Barbara (UCSB) have recently managed a remarkable breakthrough in the field of quantum mechanics. They have succeeded in detecting the quantum correlations in the result... |

Quantum mechanics and effects were a subject of controversy when they were first proposed, a few decades ago. Now, most scientists agree with the theory, or at least acknowledge it to some extent. However, it's very difficult to prove that atoms exist in two states at the same time, seeing how one of the main de... |

Researchers at the National Institute of Standards and Technology (NIST) in Boulder, Colorado, have just recently managed to devise the first quantum device, despite the fact that quantum physics and related theories have been around for a while. Thus far, no one succeeded in creating a machine that would actually ma... |

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... |

Atoms are formed of a positively charged nucleus - containing protons and neutrons - and an outer shell of electrons spinning around the nucleus. Now, we know that the nucleus is found in the center of the atom, but individual electrons spinning at high speeds around the nucleus are rather hard to localize, which is ... |

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... |

In an already random quantum world, parasite signals could spell disaster for quantum information systems. Take the example of the quantum computers. Even the slightest noise signal could bring it to a complete halt. However, parasite signals may not be as bad as previously thought, according to Seth Lloyd from the M... |

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... |

Some of you might think that creating a void is something easily achievable with today's technology, but the truth is far from reality. Not even the vacuum of space is completely empty. For example, vacuum is routinely used by physicists while undertaking studies related to quantum physics. But these vacuums are... |

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... |

Teleportation, the well-known sci-fi concept, seems closer and closer with every new discovery in quantum physics and many news articles present the recent finds as "the next step to teleportation" or "beam me up, Scotty," and the general Star Trek clichs.Really, will we ever be able to go from one place to another, ... |

Super-resolution is a technique used to enhance the resolution of an imaging system that describes rapid oscillations in an interference pattern. Scientists have been trying to create entangled states of various physical systems, but so far, it has proven hard to do.Quantum entanglement is a mechanical phenomenon tha... |

Teleportation, the movement of objects or elementary particles from one place to another, more or less instantaneously, without traveling through space, is a very popular fictional concept, appearing in numerous sci-fi productions, "Star Trek" being probably the most famous.Now, a team of scientists set a new record... |
