Once again quantum physics gives us philosophical implications: physicists showed how a small amount of randomness can be amplified without limit. Classical physics is deterministic: for example, we can determine the position and velocity of a particle at any time in the future. Quantum theory, on the other hand, states that there exist processes which…
Sometimes, particles can pass through walls. Though it sounds like science fiction, the phenomenon is well documented and even understood under the bizarre rules that govern the microscopic world called quantum mechanics. Now, scientists have measured the timing of this passing-through-walls trick more accurately than ever before, and report their results in a recent issue…
A boost for quantum reality: Theorists claim they can prove that wavefunctions are real states.
Teleportation is the extraordinary ability to transfer objects from one location to another without travelling through the intervening space. The idea is not that the physical object is teleported but the information that describes it. This can then be applied to a similar object in a new location which effectively takes on the new identity….
Spooky quantum entanglement just got spookier. Entanglement is a weird state where two particles remain intimately connected, even when separated over vast distances, like two die that must always show the same numbers when rolled. For the first time, scientists have entangled particles after they’ve been measured and may no longer even exist. If that…
A new type of quantum bit called a “phase-slip qubit,” devised by researchers at the RIKEN Advanced Science Institute and their collaborators, has enabled the world’s first-ever experimental demonstration of coherent quantum phase slip (CQPS). The groundbreaking result sheds light on an elusive phenomenon whose existence — a natural outcome of the hundred-year-old theory of…
In a feat of technical mastery, condensed-matter physicists have managed to detect the elusive third constituent of an electron — its ‘orbiton’. The achievement could help to resolve a long-standing mystery about the origin of high-temperature superconductivity, and aid in the construction of quantum computers. Isolated electrons cannot be split into smaller components, earning them…
In a study that pushed quantum mechanical theory and research capabilities to the limit, UA researchers have found a way to see the molecule that likely made the universe – or at least the hot and fiery bits of it. Lurking in the vast, chilly regions between stars, the unassuming molecule known as a triatomic…
In 1937, after the rise of quantum mechanics, Ettore Majorana, an Italian theoretical physicist, realized that the new physics implied the existence of a novel type of particles, now called Majorana fermions. After a 75-year hunt, researchers have now spotted the first solid evidence of their existence. And their discovery could hold the key to…
Scientists at the Quantum Dynamics division of the Max Planck Institute of Quantum Optics in Germany announced that they have built the very first, elementary quantum network comprised of a pair of entangled atoms that transmit information to each other via single photons. That and a couple of bucks will get you a cup of…
