Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in ...
Physics and Astronomy |As the authors report* in an upcoming issue of Physical Review A, the radio-frequency (RF) radiation could serve as a second "knob," in addition to the more traditionally used magnetic field...

Physics and Astronomy |Reactive gas-filled vapour cells can be used in frequency standard devices, especially as a cavity in <b>atomic clocks</b>, where the time is delivered during the hyperstructure transition...
Technology Offerings |Physicists are continually reaching new lows as they reduce the temperatures of samples in their laboratories. But even nano-kelvins are not low enough to overcome the entropy (a measure of th...
Physics and Astronomy |In their experiment the scientists tested a completely new principle of cooling. For this, they used the property that atoms can be stimulated by light.In this process an electron changes from...
Physics and Astronomy |Scientists at MIT have figured out a key step toward the design of quantum information networks. The results are reported in the July 20th issue of Physical Review Letters and highlighted in APS'...
Physics and Astronomy |Precise control of quantum effects is vital to the realization of entirely new technologies. For example, a computer based on quantum physical principles is expected to outperform today's classic...
Physics and Astronomy |The approach, which makes novel use of polarized light to create “effective” magnetic fields, could bring the long-sought computers a step closer to reality. A great challenge in creating a wo...
Physics and Astronomy |Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough to discern the arrival of a single atom ...
Physics and Astronomy |The team used a gas of rubidium atoms cooled to a temperature of 3 millionths of a degree above absolute zero to produce the molecule. The longest-lived molecule produced by the team survived only for...
Physics and Astronomy |In many not yet fully understood branches of physics, scientists hope to make progress with quantum computers. The special properties of the quantum particles that serve for storage and encodi...
Physics and Astronomy |Quantum computers could potentially speed up or expand present capabilities in decrypting data, searching large databases, and other tasks. The new research is published in the Feb. 12 issue of the jo...
Physics and Astronomy |The new record – 7 milliseconds for rubidium atoms stored in a dipole optical trap – is scheduled to be reported December 7 in the online version of the journal Nature Physics by researchers at the Ge...
Physics and Astronomy |The surprising experimental results agree with independent numerical simulations produced by collaborating scientists at the University of Queensland in Australia. The UA and Australian researchers ar...
