Researchers at University of Oxford have recently created a quantum memory within a trapped-ion quantum network node. Their unique memory design, introduced in a paper in Physical Review Letters, has been found to be extremely robust, meaning that it could store information for long periods of time despite ongoing network activity.

“We are building a network of quantum computers, which use trapped ions to store and process quantum information,” Peter Drmota, one of the researchers who carried out the study, told Phys.org. “To connect quantum processing devices, we use single photons emitted from a single atomic ion and utilize quantum entanglement between this ion and the photons.”

Trapped ions, charged atomic particles that are confined in space using electromagnetic fields, are a commonly used platform for realizing quantum computations. Photons (i.e., the particles of light), on the other hand, are generally used to transmit quantum information between distant nodes. Drmota and his colleagues have been exploring the possibility of combining trapped ions with photons, to create more powerful quantum technologies.

Using NASA’s Chandra spacecraft, an international team of astronomers has performed X-ray observations of the Cigar Galaxy. Results of the observational campaign, presented March 16 on the pre-print repository arXiv, deliver crucial information regarding diffuse emission from this galaxy.

Discovered in 1,774, Cigar Galaxy (Messier 82, or M82) is a starburst galaxy located some 11.73 million light years away in the constellation Ursa Major. It has a size of about 40,800 light years and is one of the closest starburst galaxies to Earth.

Observations of the Cigar Galaxy have found that it experiences a large-scale galactic wind at various wavelengths, for instance, in hard X-rays above a few keV. This superwind appears to be concentrated in the galaxy’s two high surface brightness regions or clumps, and is fueled by energy released by supernovae within the clumps that occur at a rate of about one every ten years. Previous Chandra studies of this galaxy have detected bright X-ray binaries that dominate the hard X-ray band and revealed that there is residual diffuse emission surrounding the starburst disk.

The unique radiation emitted by heated or electrified elements has been converted into sound, enabling us to hear the distinctive chord each element produces. Although the idea has been tried before, advances in technology have now made it possible for a far more complete and subtle sonification of the periodic table.

When elements are energized electrons can jump to higher energy levels. Eventually, they return to their ground state, releasing a photon in the process. The wavelength of the photon depends on the size of the energy gap between the excited state and the ground state – more energy produces higher frequency/shorter wavelength light.

Consider humanity’s astounding progress in science during the past three hundred years. Now take a deep breath and project forward three billion years. Assuming humans survive, can we even conceive of what our progeny might be like? Will we colonize the galaxy, the universe?

A Paperclip Maximizer is an example of artificial intelligence run amok performing a job, potentially seeking to turn all the Universe into paperclips. But it’s also an example of a concept called Instrumental Convergence, where two entities with wildly different ultimate goals might end up acting very much alike. This concept is very important to preparing ourselves for future automation and machine minds, and we’ll explore that today.

Johns Hopkins APL’s Civil Space Mission Area makes critical contributions to NASA and international missions to meet the challenges of space science, engineering, and exploration.

Since the dawn of the Space Age, APL has pushed the frontiers of space science, engineering and exploration. We captured the first picture of Earth from space, invented navigation by satellite, dispatched spacecraft across the solar system from our Sun to Pluto and beyond, and successfully conducted the world’s first full-scale planetary defense test mission.

We continue to shape the future by providing our nation with innovative and low-cost solutions to its space challenges. Our work includes conducting research and space exploration; development and application of space science, engineering, and technology; and production of one-of-a-kind spacecraft, instruments, and subsystems.

A planet the same size as Jupiter has been found around a surprisingly small red dwarf star about 285 light-years from our solar system. The gas giant is so large, relative to its host star, that it threatens to up-end long-held theories about how giant planets form.
