NSA May be Attempting to Exploit Practical Loops in Quantum Key Distribution

In this month's issue of Physics World, Jon Cartwright explains how the revelation that the US National Security Agency (NSA) is developing quantum computers has renewed interest and sparked debate on just how far ahead they are of the world's major labs looking to develop the same technology.

Quantum Logic Spectroscopy Extended to Photon-Recoil Spectroscopy

Quantum logic spectroscopy – which is closely linked with the name of the 2012 Nobel prize laureate, David J. Wineland – has been significantly extended: this new method is called "photon-recoil spectroscopy" (PRS). The potential of this method has been demonstrated by the research group led by Piet Schmidt from the QUEST Institute, which is based at the Physikalisch-Technische Bundesanstalt, together with colleagues from Leibniz University Hannover.

Researchers Manipulate Photons on Silicon Chip, Make Significant Progress Towards Quantum Computer

An international research group of scientists and engineers led by the University of Bristol, UK, has made an important advance towards a quantum computer by shrinking down key components and integrating them onto a silicon microchip.

Astronomers Assemble Spectroscopic Sampling of Ultra-Compact, Burned-Out Elliptical Galaxies

Astronomers using NASA's Hubble and Spitzer space telescopes, and Europe's Herschel Space Observatory, have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe.

New, Simpler Way to Achieve Quasi-Phase Matching

Color is strange, mainly due to perception. Setting aside complex brain processes, what we see is the result of light absorption, emission, and reflection. Trees appear green because atoms inside the leaves are emitting and/or reflecting green photons. Semiconductor LED brake lights emit single color light when electrical current passes through the devices.

International Collaboration to Streamline Process to Make Particle Physics Public

Ever since CERN, the European Organization for Nuclear Research in Switzerland, began its operations at the Large Hadron Collider in 2008, its researchers have pushed for their results to be publicly accessible. The field of high-energy experimental physics is a bit of an anomaly in the scientific arena. It’s a relatively small community—about 15,000 scientists globally—and one that is acutely dependent on collaboration and sharing (about half of those scientists are spread across just the four LHC experiments).

Researchers Discover How Extreme Galaxies Formed

It has long puzzled scientists that there were enormously massive galaxies that were already old and no longer forming new stars in the very early universe, approx. 3 billion years after the Big Bang. Now new research from the Niels Bohr Institute, among others, shows that these massive galaxies were formed by explosive star formation that was set in motion by the collision of galaxies a few billion years after the Big Bang. The results are published in the scientific journal, Astrophysical Journal.

NASA Provides Opportunity to Study Ultra-Cold Quantum Gases in the Microgravity Environment

NASA's Physical Science Research Program will fund seven proposals to conduct physics research using the agency's new microgravity laboratory, which is scheduled to launch to the International Space Station in 2016.

Researchers Create Synthetic Magnetic Monopoles

Nearly 85 years after pioneering theoretical physicist Paul Dirac predicted the possibility of their existence, an international collaboration led by Amherst College Physics Professor David S. Hall ’91 and Aalto University (Finland) Academy Research Fellow Mikko Möttönen has created, identified and photographed synthetic magnetic monopoles in Hall’s laboratory on the Amherst campus.

Asteroid Belt Provides New Clues to Tumultuous Past of the Solar System

Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed.

Stellar Nursery Brewing in the Trifid Nebula

A storm of stars is brewing in the Trifid nebula, as seen in this view from NASA's Wide-field Infrared Survey Explorer, or WISE. The stellar nursery, where baby stars are bursting into being, is the yellow-and-orange object dominating the picture. Yellow bars in the nebula appear to cut a cavity into three sections, hence the name Trifid nebula.

ESO's Very Large Telescope Helps Create Weather Map of Brown Dwarf

ESO's Very Large Telescope has been used to create the first ever map of the weather on the surface of the nearest brown dwarf to Earth. An international team has made a chart of the dark and light features on WISE J104915.57-531906.1B, which is informally known as Luhman 16B and is one of two recently discovered brown dwarfs forming a pair only six light-years from the Sun. The new results are being published in the 30 January 2014 issue of the journal Nature.

New Map Charts Size, Composition, and Location of More Than 100,000 Asteroids

To get an idea of how the early solar system may have formed, scientists often look to asteroids. These relics of rock and dust represent what today's planets may have been before they differentiated into bodies of core, mantle, and crust.

Quantum-Mechanical Effects May Help Exceed Theoretical Limit for Efficiency of Ideal Solar Cells

A new theoretical model developed by professors at the University of Houston (UH) and Université de Montréal may hold the key to methods for developing better materials for solar cells.
