Transistor laser functions as non-linear electronic switch, processor
The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and permit its use as a dual-input, dual-output, high-frequency signal processor. view more (2006-02-07)
JILA solves problem of quantum dot 'blinking'
Quantum dots-tiny, intense, tunable sources of colorful light-are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a secret problem, a kind of nervous tic. They mysteriously tend to "blink" on and off like Christmas tree lights, which can reduce their... view more...

Inside a quantum dot: Tracking electrons at trillionths of a second
Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. view more (2005-11-28)
Physics breakthrough much ado about 'nothing'
How do scientists store nothing? It may sound like the beginning of a bad joke, but the answer is causing a stir in the realm of quantum physics after two research teams, including one from the University of Calgary, have independently proven it's possible to store a special kind of vacuum in a puff of gas and then retrieve it a split second later. view more (2008-03-06)
Laser treatment
Researchers in Russia have used laser treatment to cure male sexual dysfunction. The Institute of Physics magazine - Opto & Laser Europe - reports this week that after treatment with a device developed by Ekaterina Koultchavenia of the Novosibirsk Research Institute, all 24 male patients in the trial re-gained the ability to have spontaneous... view more...

Graz team sheds new light on dark states - another Austrian breakthrough in quantum physics
Vienna, 16 June 2003 Light shines through opaque materials if certain conditions are met. By establishing the existence of another such condition, scientists at the Graz University of Technology have created additional possibilities for using light to control revolutionary new optical components. The project, funded by the Austrian Science Fund... view more... (2003-06-16)
UCSB physicists move 1 step closer to quantum computing
Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. view more (2009-11-20)
Tossing a coin in the microcosm
When you toss a coin, you either get heads or tails. By contrast, things are not so definite at the microcosmic level. An atomic 'coin' can display a superposition of heads and tails when it has been thrown. view more (2009-07-10)
Enzyme and vitamin define the yin and yang of asthma
The allergen breathed in by a person with asthma triggers a proteinase or enzyme called MMP7 that activates a cascade of events to prompt an allergic reaction. view more (2009-03-30)

The next step in quantum computing
A team of physicists in the United States has made an important step towards making quantum computing a reality. Research into a new type of noiseless quantum information bit, or qubit, is published today in the joint Institute of Physics and German Physical Society journal, New Journal of Physics. view more (2002-02-12)
Thousands of atoms swap 'spins' with partners in quantum square dance
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have induced thousands of atoms trapped by laser beams to swap "spins" with partners simultaneously. view more (2007-07-26)
World's most powerful ultraviolet laser inaugurated
Titania will be the most powerful ultraviolet laser world-wide and has the capacity to generate up to 10 terawatt power in single pulses of duration down to 300 femtoseconds. It will be inaugurated at a special ceremony today (Tuesday 2 April) by Dr Paul Williams, Chief Executive of CCLRC, who will fire the new facility's first shot. Titania is... view more...

Atoms don't dance the 'bose nova'
Hanns-Christoph Naegerl's research group has investigated how ultracold quantum gases behave in lower spatial dimensions. They successfully realized an exotic state, where, due to the laws of quantum mechanics, atoms align along a one-dimensional structure. view more (2009-09-04)
Classical Physics falls short
With the aid of so-called quantum dots, PhD student Wilfred van der Wiel has gained new insight into quantum-mechanical processes. "This is one of the paths that could lead to smaller, but also fundamentally different electronics, " says Van der Wiel. He will receive his degree on 28 January for his fundamental research. Parts of his... view more... (2002-01-20)
UA scientists discover quantum fingerprints of chaos
Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics. view more (2009-10-08)
