While the laws of physics weren't made to be broken, sometimes they need revision. A major current law has been rewritten thanks to the three-port transistor laser, developed by Milton Feng and Nick Holonyak Jr. at the University of Illinois. With the transistor laser, researchers can explore the behavior of photons, electrons and semiconductors. The device could shape the future of high-speed signal processing, integrated circuits, optical communications, supercomputing and other...

A team from Cardiff University's School of Physics and Astronomy fired light particles, or photons, into a tiny tower of semi-conducting material. A photon collides with an electron confined in an even smaller structure within the tower, and they oscillate briefly between the states of light and matter, before the photon re-emerges. The Cardiff team have conducted this experiment with both individual and pairs of photons. They showed that photon pairs increase the frequency of the oscillation...

Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and "“ most importantly "“ certified random by laws of physics. That is important because randomness is surprisingly rare. Although the welter of events that transpire in the course of daily life can certainly seem haphazard and arbitrary, none of them is genuinely random in the sense that they could not be predicted...

Physicists study single-atom lasers Rainer Blatt's and Piet Schmidt's research team from the University of Innsbruck have successfully realized a single-atom laser, which shows the properties of a classical laser as well as quantum mechanical properties of the atom-photon interaction. The scientists have published their findings in the journal Nature Physics. The first laser was developed 50 years ago. Today we cannot imagine life without the artificially produced light waves - lasers have...

Like playing a game of scissors-paper-rock, a team of scientists led by Thornton E. (Ernie) Glover of Berkeley Lab's Advanced Light Source (ALS), Linda Young of Argonne National Laboratory, and Ali Belkacem of Berkeley Lab's Chemical Sciences Division has used laser light to control x-ray beams "“ by first changing the material medium through which the x-rays pass. As a new generation of powerful light sources comes online, intense x-ray beams may be able to control matter directly and...

The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms. A German-Spanish research group, split between the Max Planck Institute for Quantum Optics in Garching and the Institute of Photonic Sciences (ICFO), is using the principles of an iconic quantum mechanics thought...

Max Planck physicists develop an experiment to investigate the random motion of quantum particles Life would sometimes be so much easier if we were quantum particles. For example, if we were trying to find our way out of a strange town allowing chance telling us which way to go at every intersection. As objects of classical physics, this would mean becoming more and more lost in the center of the road network. If we were particles that obeyed the laws of quantum mechanics, we would sooner or...

University of Calgary researchers use quantum entanglement to stack light particles While many of us enjoyed constructing little houses out of toy bricks when we were kids, this task is much more difficult if bricks are elementary particles. It is even harder if these are particles of light "“ photons, which can only exist while flying at an incredible speed and vanish if they touch anything. A team at the University of Calgary has accomplished exactly that: by manipulating a mysterious...

Diamond nanowire device could lead to new class of diamond nanomaterials suitable for quantum cryptography, quantum computing, and magnetic field imaging By creating diamond-based nanowire devices, a team at Harvard has taken another step towards making applications based on quantum science and technology possible. The new device offers a bright, stable source of single photons at room temperature, an essential element in making fast and secure computing with light practical. The finding...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...
