Plenty of nothing: A hole new quantum spin
Electronic devices are always shrinking in size but it's hard to imagine anything beating what researchers at the University of New South Wales have created: a tiny wire that doesn't even use electrons to carry a current. view more (2006-07-26)
Scientists create first working model of a 2-qubit electronic quantum processor
A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. view more (2009-07-01)
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)
A quantum (computer) step
A University of Utah physicist took a step toward developing a superfast computer based on the weird reality of quantum physics by showing it is feasible to read data stored in the form of the magnetic "spins" of phosphorus atoms. view more (2006-11-20)
Evidence of macroscopic quantum tunneling detected in nanowires
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more... view more...

X marks the spot: Ions coldly go through NIST trap junction
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a new ion trap that enables ions to go through an intersection while keeping their cool. view more (2009-04-09)
Light touch: Controlling the behavior of quantum dots
Researchers from the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI), a collaborative center of the University of Maryland and NIST, have reported a new way to fine-tune the light coming from quantum dots by manipulating them with pairs of lasers. view more (2008-08-20)
Weizmann Institute Scientists Find New 'Quasiparticles'
Weizmann Institute physicists have demonstrated, for the first time, the existence of 'quasiparticles' with one quarter the charge of an electron. This finding could be a first step toward creating exotic types of quantum computers that might be powerful, yet highly stable. view more (2008-06-03)
U-M physicists create first atomic-scale map of quantum dots
University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications. view more (2009-09-30)
Researchers set new record for brightness of quantum dots
By placing quantum dots on a specially designed photonic crystal, researchers at the University of Illinois have demonstrated enhanced fluorescence intensity by a factor of up to 108. Potential applications include high-brightness light-emitting diodes, optical switches and personalized, high-sensitivity biosensors. view more (2007-09-26)
Quantum paradox directly observed -- a milestone in quantum mechanics
In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum... view more...

Closing In On Quantum Chemistry
Researchers in the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have simulated the process by which a quantum computer could calculate to high precision an important basic property of two small molecules. view more (2005-09-09)
Computer hackers R.I.P. -- making quantum cryptography practical
Quantum cryptography, a completely secure means of communication, is much closer to being used practically as researchers from Toshiba and Cambridge University's Cavendish Laboratory have now developed high speed detectors capable of receiving information with much higher key rates, thereby able to receive more information faster. view more (2009-04-30)
Physicists produce quantum-entangled images
Using a convenient and flexible method for creating twin light beams, researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland have produced "quantum images," pairs of information-rich visual patterns whose features are... view more...

Researchers unite to distribute quantum keys
Researchers from across Europe have united to build the largest quantum key distribution network ever built. view more (2009-07-02)
Danish Researchers Break the Limits of the Internet
A team of Danish physicists has taken a crucial step towards an Internet that is faster and more secure than what we know today. The researchers from the Niels Bohr Institute at the University of Copenhagen have created an atomic memory that, in time, will be able to break the limits for Internet communication. The team's breakthrough was... view more... (2004-11-26)
Using Carbon Nanotubes For Quantum Computing
The computing community for many years has longed to be able to to carry out high speed calculations using a genuine Quantum Computer because it would facilitate the practical factorisation of very large numbers and the searching of unordered lists and databases. The rapid breaking of secure codes based on prime numbers would have a lot of... view more... (2004-07-15)
Quantum biology — Powerful computer models reveal key biological mechanism
Using powerful computers to model the intricate dance of atoms and molecules, researchers at Rensselaer Polytechnic Institute have revealed the mechanism behind an important biological reaction. view more (2007-01-17)
First tunable, 'noiseless' amplifier may boost quantum computing, communications
Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier. view more (2008-10-16)
Delft University of Technology rotates electron spin with electric field
Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields. view more (2007-11-02)
