It’s not what you’ve been told

Probability solves a great question of time travel. Well, probably.

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 […]

Is everything in the universe made up of vibrating one-dimensional strings? For the first time, scientists think they can concretely…

How fast is too fast? According to the laws of physics, the speed of light is a good boundary, as…
