The Lead

As the Earth rotates every 24 hours, the orientation of the ions in the quantum computer/detector changes with respect to the Sun’s rest frame. If space were squeezed in one direction and not another, the energies of the electrons in the ions would have s

Quantum Computer’s Extremely Precise Measurements Show Space is Not Squeezed

January 29, 2015 3:19 pm | by Robert Sanders, UC Berkeley | News | Comments

Ever since Einstein proposed his special theory of relativity, physics and cosmology have been based on the assumption that space looks the same in all directions — that it’s not squeezed in one direction relative to another. A new experiment used partially entangled atoms — identical to the qubits in a quantum computer — to demonstrate more precisely than ever before that this is true, to one part in a billion billion.

Suddenly, scientists are sexy. With Benedict Cumberbatch nominated for multiple trophies as Alan Turing and Eddie Redmayne turning heads as Stephen Hawking, young British actors playing scientists are all the rage this season. So, it's good timing for the Royal Shakespeare Company, whose new play, Oppenheimer, features John Heffernan as American scientist J.

We're Two Minutes Closer to Doomsday

The Bulletin of the Atomic Scientists says Earth is now closer to human-caused doomsday than it has been in more than 30 years because of global warming and nuclear weaponry. But other experts say that's way too gloomy. The advocacy group, founded by the creators of the atomic bomb, moved their famed "Doomsday Clock" ahead two minutes on January 22, 2015. It said the world is now three minutes from a catastrophic midnight.

Predicting Concrete Flow Properties from Simple Measurements

January 23, 2015 2:44 pm | by NIST | News | Comments

Just because concrete is the most widely used building material in human history doesn’t mean it can’t be improved. A recent study using DOE Office of Science supercomputers has led to a new way to predict concrete’s flow properties from simple measurements. The results should help accelerate the design of a new generation of high-performance and eco-friendly cement-based materials by reducing time and costs associated with R&D.

Rice-sized Laser, Powered One Electron at a Time, Bodes Well for Quantum Computing

Researchers have built a rice-grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental interactions between light and moving electrons. The researchers built the device — which uses about one-billionth the electric current needed to power a hair dryer — while exploring how to use quantum dots.

Optimizing Information Transfer for a Quantum Internet

A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. Physicists have shown how this information transfer can be optimized by taking advantage of a collective quantum phenomenon. The collective interaction between the particles and the resonator can now be tuned in order to enhance the creation of single photons.

By analyzing the light of hundreds of thousands of celestial objects, astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars, called diffuse interstellar bands. DIBs have been a mystery ever since they were discovered in 1922 — exactly which of the many thousands of possible molecules are responsible for these features?

Vanishing Neutron Star used to Measure Space-time Warp with Extreme Precision

In an interstellar race against time, astronomers were able to measure the space-time warp in the gravity of a binary star and determine the mass of a neutron star — just before it vanished from view. The team measured the masses of both stars in binary pulsar system J1906. The pulsar spins and emits a lighthouse-like beam of radio waves every 144 milliseconds. It orbits its companion star in a little under four hours.

Iron Sun: Not a Rock Band, but a Key to Stars’ Energy Transmission

Working at temperatures matching the interior of the sun, researchers have been able to determine, for the first time in history, iron’s role in inhibiting energy transmission from the Sun's center to near the edge of its radiative band. Because that role is much greater than formerly surmised, the experimentally derived amount of iron’s opacity helps close a theoretical gap in the Standard Solar Model, used to model the behavior of stars.
