Fermi Bubbles Are Burps from a Star-Eating Black Hole. The following story may be recalled from almost a year ago, if only because of the eye-catching illustration: NASA’s Fermi Telescope Finds Giant Structure in our Galaxy NASA’s Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way.
The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy. “What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center,” said Doug Finkbeiner, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who first recognized the feature. “We don’t fully understand their nature or origin.” Since gamma rays are the most energetic form of electromagnetic radiation (far more potent than X-rays), the existence of large, though diffuse, clouds of them above and below the plane of our galaxy wasn’t something to be taken lightly.

We demonstrate a quantum central processing unit that exchanges data with a quantum random-access memory integrated on a chip, with instructions stored on a classical computer.
We test our quantum machine by executing codes that involve seven quantum elements: Two superconducting qubits coupled through a quantum bus, two quantum memories, and two zeroing registers.
