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...

BOSTON, Feb. 4 /PRNewswire/ -- With solar electricity generating more than one terawatt-hour (one billion kilowatt hours) of electricity in the United States in 2010 and continuing to expand rapidly, the key question is, "How can companies best capture value as the industry grows?", according to Michael Rogol, global PV analyst and CEO of Boston-based PHOTON Consulting. "The U.S. solar power sector is very profitable, but value is migrating from companies that manufacture toward companies...

BOSTON, Jan. 29 /PRNewswire/ -- In his State of the Union address to Congress, US President Obama highlighted the importance of solar power to America's future and stressed that, "It is time for America to lead again." With the strong support of government incentives and declining system prices, demand for solar photovoltaic (PV) systems in the United States is showing steady growth, yielding an increasing number of watt-hours of solar electricity generation and solar jobs. For the first...

BOSTON, Jan. 13 /PRNewswire/ -- Solar companies at every step of the global PV supply chain must begin to focus resources on developing the end-markets that will support the industry in the event of another major market saturation, according to the recently released market report by PHOTON Consulting, Solar Power Markets: Prepare for Impact. "During 2009, the global PV sector became overly dependent on a few dominant end markets. As rapid supply growth returns to the sector, we fear that...

Quantum entanglement achieved in solid-state circuitry For the first time, physicists have convincingly demonstrated that physically separated particles in solid-state devices can be quantum-mechanically entangled. The achievement is analogous to the quantum entanglement of light, except that it involves particles in circuitry instead of photons in optical systems. Both optical and solid-state entanglement offer potential routes to quantum computing and secure communications, but solid-state...

Researchers at the California Institute of Technology (Caltech) have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their ideas, described in the latest online issue of the Proceedings of the National Academy of Sciences, offer a new means of addressing one of the most fascinating issues in quantum mechanics: the nature of quantum superposition and entanglement in progressively larger and more complex systems. A quantum...

Nanotechnology has already made it to the shelves of your local pharmacy and grocery: nanoparticles are found in anti-odor socks, makeup, makeup remover, sunscreen, anti-graffiti paint, home pregnancy tests, plastic beer bottles, anti-bacterial doorknobs, plastic bags for storing vegetables, and more than 800 other products. How safe are these products and the flood of new ones about to spill out of labs across the world? A group of researchers at Washington University is devising instruments...

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...
