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

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...

Transmitting extremely precise clock signals over long distances could help pave the way to a new definition of the second Atomic clocks based on the oscillations of a cesium atom keep amazingly steady time and also define the precise length of a second. But cesium clocks are no longer the most accurate. That title has been transferred to an optical clock housed at the U.S. National Institute of Standards and Technology (NIST) in Boulder, Colo. that can keep time to within 1 second in 3.7...

Atomic Clock Comparison Via Data Highways
2012-04-27 08:58:02

In future, optical fibers could connect all optical atomic clocks within Europe — a milestone for various users of optical frequencies in research and industry Optical atomic clocks measure time with unprecedented accuracy. However, it is the ability to compare clocks with one another that makes them applicable for high-precision tests in fundamental theory, from cosmology all the way to quantum physics. A clock comparison, i.e. a comparison of their optical frequencies, proved to...

NASA To Fly Deep Space Atomic Clock To Improve Navigation Technology
2012-04-11 13:29:41

When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems. Another critical piece of spaceflight technology, however, is an ultra stable, highly accurate device for timing - essential to NASA's success on deep-space exploration missions. NASA is preparing to fly a Deep Space Atomic Clock, or DSAC, demonstration that will revolutionize the way we conduct deep-space navigation by...
