Quantum mechanics (QM â also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at microscopic scales, where the action is on the order of the Planck constant. Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter.
For the first time ever the shadow of an atom (yes, even an atom can cast a shadow) has been imaged using a complex technique which involved a laser beam and a a Fresnel lens. The culmination of their five-year work is this fantastic snapshot from above, and although this dark spot is quite tiny, the [...]
Last May, European scientists managed to teleport photons using quantum phenomena over a distance of 143 kilometers, across two Canary islands; however, it is only now that their paper was accepted in a peer reviewed magazine. Beam me up, Scotty While the technology used in Star Trek is still only science-fiction, the quantum teleportation of [...]
Hailed as yet another big step towards devising working quantum computers, scientists at Ruhr-Universität Bochum (RUB) have successfully managed to generate quantum qubits inside a semiconductor for the first time, instead of vacuum. A qubit is the quantum analog of a bit. While a bit must be read either as a 0 or 1, the qubit can [...]
By harnessing the science of both quantum and nano physics, scientists at the Niels Bohr Institute have come up with an innovative new way of cooling semiconductor membranes by using laser light. Through this new technique, the researchers were able to cool the tiny, thin membrane from room temperature to -269 degrees Celsius. Paradoxically, the [...]
Researchers have successfully managed to create a “solar paint” made out of quantum dots, which exhibits similar properties to multifilm solar cell architectures. The later are sophisticated, expensive and require a lot of time to deploy; the paint can be easily applied to basically any surface, like a house’s roof, and prepare it to easily generate [...]
A team of researchers from led by Guillaume Gervais from McGill’s Physics Department and Mike Lilly from Sandia National Laboratories, have managed to develop one of the smallest electronic circuits in the world using nanowires spaced across each other by a distance so small, it has to be measured at an atomic level. Miniaturization has been [...]
Does flicking a dice really render a random face? The answer would be no. The dice is governed by large-scale conventional physics and its motion, and thus final position can be determined. You can’t tell where it lands just by looking at it thwirl, of course, but the fact remains it’s not random, and neither [...]
What you just saw in the video above is a perfect demonstration of the quantum levitation effect, through a fairly simple set-up made by Tel Aviv University scientists, comprised of a track and a semiconductor. The quantum levitation is actually a perfect demonstration of the Meissner effect, which describes the expulsion of a magnetic field [...]
