Device For Portable, Ultra-precise Clocks And Quantum Sensors Developed By Scientists
2013-05-09 10:59:35

University of Strathclyde In a joint project between the Universities of Strathclyde and Glasgow, Imperial College London and the National Physical Laboratory, researchers have developed a portable way to produce ultracold atoms for quantum technology and quantum information processing. Their research has been published in the journal Nature Nanotechnology, where it is featured on the front cover. Many of the most accurate measurement devices, including atomic clocks, work by...

Berkeley Physicist Uses Atomic Matter To Tell Time
2013-01-11 15:06:34

Brett Smith for redOrbit.com - Your Universe Online In a groundbreaking new study, physicists from the University of California, Berkeley have used atomic matter to measure time. According to a new report in the journal Science, Holger Müller and his Berkeley colleagues describe how to tell time using a cesium atom and the theory that matter can be both a particle and a wave. "When you make a grandfather clock, there is a pendulum and a clockwork that counts the...

Better Accuracy For Optical Strontium Clock
2013-01-03 11:30:03

Alpha Galileo Foundation PTB measures the influence of the ambient temperature on strontium atoms for the first time — measurement uncertainty reduced by one order of magnitude An optical clock with neutral strontium atoms is considered one of the top candidates for the definition of a "new" second. The probabilities have increased considerably, since its frequency will now be determined more accurately (probably by an order of magnitude). Scientists of the Physikalisch-Technische...

Atomic Clocks May Survey Earth's Insides
2012-11-12 15:17:48

Lee Rannals for redOrbit.com - Your Universe Online Scientists say they are planning to use portable atomic clocks to help identify mineral deposits and concealed water resources inside the Earth. An international team believes that atomic clocks could already have reached the necessary degree of precision to be useful for geophysical surveying. They said that these clocks will provide the most direct measurement of the geoid, which is the Earth's true physical form. The Earth's...

Atomic Clocks Get Boost From The Most Stable Laser In The World
2012-09-15 07:00:47

April Flowers for redOrbit.com -- Your Universe Online An international team of scientists has developed a laser with a frequency stability previously unequalled. This is the result of a research cooperation of the Physikalisch-Technische Bundesanstalt (PTB) within the scope of the Excellence Cluster QUEST (Centre for Quantum Engineering and Space-Time Research) with colleagues from the National Institute of Standards and Technology/JILA. Their development, published in the journal...

Researchers Take A New Look At Masers
2012-08-17 05:39:36

Michael Harper for redOrbit.com — Your Universe Online While we´ve been fixated with lasers – shooting them from flying ships, attaching them to shark´s heads, what have you – there´s been another sort of beam waiting in the wings for someone to take notice. In fact, "Masers" have been around before their cooler, younger sibling the Laser. They´ve also been more difficult to generate, requiring high magnetic fields and plenty of cooling. Masers are...

New Device For Quantum Information Processing
2012-07-24 11:14:28

A groundbreaking new device from the National Physical Laboratory could help to usher in the long-awaited era of quantum computers Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits (qubits). The research, published in Nature Nanotechnology, shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device's ability to confine...

Leap Second
2012-06-30 10:41:36

Michael Harper for redOrbit.com — Your Universe Online Is there anything a scientist can´t do? Looking past the state of mobile computing – which is already pretty amazing, when you think about it – there are scientists and researchers who are planning trips to the moon as well as growing bio-computers, living computers, in their labs. What will they think of next? With some clever understanding of the Earth´s rotation and a little trickery, scientists at the...
