Building a quantum computer is one of the main efforts currently being made in the fields of information technology, nanotechnology and quantum physics. The reason why so many people want to see the device built is its amazing potential computational power, which could see seemingly unbreakable problems being figured... |

Scientists at the US National Institute of Standards and Technology (NIST) announce the development of the first 'universal' programmable quantum information processor, which uses two quantum bits (qubits) of information. According to the team behind the groundbreaking achievement, the processor can be empl... |

Scientists at the Delft University of Technology Kavli Institute for Nanosciences, in the Netherlands, have recently managed to gain new control over the environment of quantum particles, which may make it possible to finally construct a working quantum computer. The new finds essentially allow researchers to exercis... |

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... |

Quantum computers are currently one of the largest objectives for the electronics industry. They will be able to calculate immensely complicated codes faster and more accurately than the current technology can, as they will make use of the quantic principle of superposition. This principle dictates that a quantum bit... |

Experts from the University of California in Santa Barbara (UCSB) have recently announced that they managed to create a new type of circuit that behaves in a quantum mechanic manner. They say that the innovative device does not have the regular two levels of energy, but that it boasts a full five of them. Details of ... |

Experts have been working hard on overcoming the obstacles that stand in the way of creating a fully functional quantum computer for quite some time now, but one of the main issues in their path was the fact that they could not control the actions of a single qubit (quantum bit – the basic unit of a quantum pro... |

Ion traps haven't been a thing of novelty for a very long time, ever since they started being used regularly in atomic clocks, as well as in lines of research related to quantum computing development. Ions, which are essentially electrically charged atoms, move through these so-called traps, and experience all s... |

The principle of “quantum ghosts” was first inferred by Albert Einstein, who was so worried about it that he called it “spooky action at a distance.” It refers to the apparent ability that some particles have to interact with each other over very long distances, even though they are not direct... |

There is a growing consensus at the international level that quantum computers are the future of complex calculations, but the goal of having such devices that actually work remains distant, on account of the fact that the very basic principles on which quantum technology is based are very unstable. This means that a... |

Creating junctions inside future quantum processors is a very important step in their design. Actually, some may argue that this is the most important step, as, without a pathway to carry information from one place to the other inside a processor, all other innovations in the area are useless. However, the main probl... |

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... |

Men around the world can now start celebrating the creation of the world's smallest diamond ring! Now everybody can afford a diamond ring. Too bad it is only 5 millionths of a meter in diameter and bears five-billionths of a carat of diamond, this meaning it can only be viewed through a microscope. The proud inv... |

Most of the experiments carried out on quantum computer models revolve around the use of gallium arsenide chips to create quantum dots. However, it seems that such a material is not exactly the ideal one when trying to control the spin of an electron inside a quantum dot. The solution for the problems experienced wit... |
