Novel Technique to Manipulate Electronic Spin of Qubits Using Light Pulses

By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond –– the nitrogen-vacancy center –– in a method that not only allows for more unified control than conventional processes, but is more versatile, and opens up the possibility of exploring new solid-state quantum systems. Their results are published in the latest edition of the Proceedings of the National Academy of the Sciences.

CERN to Restore the World's First Website

Twenty years ago CERN1 published a statement that made the World Wide Web ("W3", or simply "the web") technology available on a royalty-free basis. By making the software required to run a web server freely available, along with a basic browser and a library of code, the web was allowed to flourish.

Subtle Difference between Matter and Antimatter Observed

A subtle difference between matter and antimatter has been observed for the first time by the Large Hadron Collider beauty (LHCb) experiment at the European Organisation for Nuclear Research (CERN).

Laws of Quantum Physics Can Also Impact on Molecular Levels

New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of ‘classical’ physics that govern our everyday world.

White Dwarf Star Orbits Massive Neutron Star to Form a Bizarre Stellar Pair

Astronomers have used ESO’s Very Large Telescope, along with radio telescopes around the world, to find and study a bizarre stellar pair consisting of the most massive neutron star confirmed so far, orbited by a white dwarf star.

Powerful Winds Due to Starbursts Ionize Gas around the Host Galaxy

When galaxies form new stars, they sometimes do so in frantic episodes of activity known as starbursts. These events were commonplace in the early Universe, but are rarer in nearby galaxies.

Strange Stellar Pair Provides Unique Cosmic Laboratory for Study of Gravity’s Nature

A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive neutron star in orbit with a companion white dwarf star puts competing theories of gravity to a test more stringent than any available before.

New Image Reveals Detailed Structure of Matter Being Thrown Off Betelgeuse Red Star

Astronomers have released a new image of the outer atmosphere of Betelgeuse – one of the nearest red supergiants to Earth – revealing the detailed structure of the matter being thrown off the star.

CERN LHCb Collaboration Submits Paper on First Observation of Matter-Antimatter Asymmetry

The LHCb collaboration at CERN today submitted a paper to Physical Review Letters on the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s. It is only the fourth subatomic particle known to exhibit such behaviour.
