In their quest for ever-smaller and ever-faster computer chips and transistors, scientists have, over the past few years, dedicated enormous amounts of time, energy, and money to producing electronics at the smallest scale possible. This has gone all well and good for some years, but now this field of research is app... |

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... |

Graphene, the one-atom-thick sheet of carbon atoms that was discovered in 2004 at the University of Manchester, is the most avidly researched material today in the field of condensed-matter physics. Because electrons flow in a very peculiar way through it, experts believe it may constitute the replacement of choice f... |

One of the most basic principles in quantum physics is that an object in a closed system with no observers can exist in more than one states at the same time. This was made clear in 1935 by Austrian physicist Erwin Schrödinger, who proposed his famous cat example. Now, experts are planning to perform the same se... |

Scientists from the University of Missouri have recently announced that they've created the most precise measurements to date of the curvature of space caused by the Sun's gravity in our solar system. The research was conducted using the National Science Foundation's (NSF) Very Long Baseline Array (VLB... |

Black holes, once highly misunderstood formations, have over the years captured the imagination of astronomers and film producers alike, and have been prominently featured in films and in literature. In spite of the high levels of attention they were given, there are still a great many things that remain unknown abou... |

Ultracold atomic gases are the standard in quantum physics observations, mostly because they can offer unprecedented insight into the effects that appear when transitions from one quantum state to the other take place. While these transitions are usually fun to look at, they are even more spectacular at the quantum l... |

Albert Einstein's famous theory of general relativity and the quantum mechanics theory are two of the most complete methods we have of explaining our surrounding realities. However, each of them only describes a part of the Universe, so an idea that would unify the two has been sought for over the last decades. ... |

Quantum physics is a remarkable field of research for new ideas and technologies that could benefit mankind, as soon as you learn how to get over the fact that just about everything in it doesn't make sense. Particles exist in two states at the same time, and they can communicate with each other over incredibly ... |

Since it was first discovered in 2004, graphene has been one of the materials largely touted as having the potential to completely revolutionize the world, at least in terms of electronic devices. Believed to be a sustainable alternative to the silicon used in modern chips, the carbon compound has proven its abiliti... |

More than 41 research and industrial organizations in Europe have recently joined efforts in their attempt to create the world's largest quantum key distribution network, through which data are transfered using only quantum inscription. This is by far the largest such network ever built anywhere on the globe, an... |

For the first time ever, researchers from the Yale University have demonstrated a solid-state quantum processor, made of a two-qubit superconducting chip. The team behind the accomplishment also managed to run a few basic operations on the machine, such as a search query. Their work takes a major step forward in crea... |

Over recent years, many popular books and movies have made us wonder whether we are in touch with a “cosmic consciousness,” through the mechanisms of quantum physics. Butterfly effects, separate realities, and collective consciousnesses are all themes that have been exploited to the full, albeit not alway... |

Since the dawn of mankind, people have always looked upwards in admiration of the flocks of birds heading towards their summer or winter places, stretching wide across the sky, and flying purposefully in a single direction each year. How the animals managed to keep their direction and not get lost was a question few ... |

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... |

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... |

Fractals, rough and irregular geometric shapes whose components have approximately the same form as the whole, may be the key to understanding the quantum world, physicists say. Endowed with the property of self-similarity, fractals can hardly be described by Euclidean geometry, in that they are rarely a common shape... |

The limit of diffraction that most crystal types employ has been for a long time a very difficult obstacle in the path of scientists trying to take a closer look at the atomic structure of these materials. Now, experts at the University of Illinois have managed to achieve a breakthrough in the field, by devising a me... |

Scientist have known for a long time that atoms placed in various specific conformations have the potential to make electrons around them dance in a “quantum” way, but have until now failed to create such an alignment. But the February 13th edition of the journal Science hosts a new scientific study that ... |

For decades, physicists have been hypothesizing about the existence of a fourth dimension, or even a fifth, seventh and a tenth one. But figuring out how each of them works and what holds them together has been no easy task, as proven by the fact that the brightest minds in the field today, which are still working on... |

In a recent book, physicist Joao Magueijo explains the principles of his varying-speed-of-light (VSL) theory, claiming that light can outrun itself. This idea of velocities beyond that of light has been discussed before, as two German scientists claim their quantum tunneling experiments proved it was possible. ... |

Although Bose-Einstein condensates are usually very large, consisting of hundreds of thousands of atoms, they still follow quantum mechanics laws, which makes them so important in the study of the properties of quantum mechanics. "Over the years, work on Bose-Einstein condensates, known as BECs, have led to more and ... |

One of the most intriguing physical puzzles related to quantum physics and particle physics is a property of the protons, which all elementary particles share, called spin. The spin number, or quantum momentum, represents the particle's rotation around its own axis, but unlike the gyroscopic instruments and spin... |
