It was a good day for Einstein when an international collaboration of physicists announced in February that they detected ripples in space time known as gravitational waves from the collision of two gigantic black holes far far away. Neither gravitational waves nor black holes — both predictions of Einstein’s theory of gravity, general relativity — had been seen directly before.

The National Academy of Sciences announced today (5/3/2016) the election of 84 new members and 21 foreign associates from 14 countries in recognition of their distinguished and continuing achievements in original research.
Those elected today bring the total number of active members to 2,291 and the total number of foreign associates to 465. Foreign associates are nonvoting members of the Academy, with citizenship outside the United States.

By using photons to communicate between two electrons through more than a mile of fiber optic cable, physicists have taken an important step toward proving the practicality of quantum networks.

Quantum information science opens new opportunities for future information-processing architectures that exploit the fundamental properties of quantum mechanics. Quantum information processing (QIP) has two essential ingredients: elementary quantum logic gates and remote communication of quantum information.

Spotlight summary: The concept of quasi-phase-matching (QPM) was introduced at the very beginning of the era of lasers and nonlinear optics as a generic method to increase the efficiency of second order nonlinear interactions. However, it was not until the early 90’s, with the introduction of periodically poled ferroelectrics obtained by electric field poling that the technique began to blossom as an engineering tool to tailor nonlinear interactions.

Long-wavelength pumped, periodically poled lithium niobate waveguides upconvert single photons, allowing efficient, low-noise silicon avalanche photodiodes to detect the signal.
