In physics, a quantum (plural: quanta) is the minimum amount of any physical entity involved in an interaction. Behind this, one finds the fundamental notion that a physical property may be "quantized," referred to as "the hypothesis of quantization".[1] This means that the magnitude can take on only certain discrete values. There is a related term of quantum number. An example of an entity that is quantized is the energy transfer of elementary particles of matter (called fermions) through bosons and of photons.[clarification needed]
Most physicists believe that space is not smooth, but it is rather composed of incredibly small subunits, much like a painting made of dots. This micro-landscape is believed to host numerous black holes – black holes, that is, smaller than a trillionth of a trillionth of the diameter of a hydrogen atom, popping in and [...]
The quantum world is entirely different from what we see around us; it has its own laws, its own algebra, etc. It’s a really bizarre place, but that can yield wonderous developments as well. Since the quantum laws are so different, it’s hard to actually observe them, so instead, thought experiments are used. But for [...]
The world we live in is getting closer and closer to Star Trek everyday. Scientists announced today they were able to teleport special bits of light from one place to another. While this doesn’t mean that we will be (ever) able to teleport people, it involves some pretty awesome mind bending physics. Teleportation relies on [...]
In case you’re wondering, what you’re looking at is a silicon chip, only 1 millimeter square that was used by researchers to prove how data can be stored in the magnetic spin of atoms – and how it can then be accessed electronically. Physicists from the University of Utah have managed to store information in [...]
Since the Large Hadron Collider went back in business, all sort of rumors have been circling the scientific circles (and not only). However, until these rumors are proven wrong or right, the first official paper on proton collisions from the Large Hadron Collider has been published in this week’s edition of Springer’s European Physical Journal [...]
Well, rumors and science never go well together, especially when it goes to something as important as the work going on at LHC, who just got back in business a short while ago. My first reaction was to believe it was just a rumor. However, after hearing and reading many articles on this (including something [...]
Physicists from NIST (National Institute of Standards and Technology) have demonstrated what they claim to be the first universal programmable quantum information processor that will be able to run any program allowed by quantum mechanics (the set of principles that describe the atomic and subatomic matter). They managed to accomplish this using two quantum bits [...]
The first experiments with this laser (Linac Coherent Light Source) have been given the green light at the Department of Energy’s SLAC National Accelerator Laboratory. The illuminating of objects and processing speed will take place at an unprecedented scale, promising groundbreaking research in physics, chemistry, biology and numerous other fields. “No one has ever had [...]
