New, better way to build circuits for world's first useful quantum computers
New, better way to build circuits for world's first useful quantum computers 27 June 2016The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance, using a 3-dimensional array of atoms in quantum states called quantum bits -- or qubits -- was made by David S. Weiss, professor of physics at Penn State University, and three students on his lab team.
Fastest-spinning brown-dwarf star is detected by its bursts of radio waves
Fastest-spinning brown-dwarf star is detected by  its bursts of radio waves 24 June 2016Astronomers have detected what may be the most-rapidly-rotating, ultra-cool, brown-dwarf star ever seen. The super-fast rotation period was measured by using the 305-meter Arecibo radio telescope -- the same telescope that was used to discover the first planets ever found outside our solar system.
New gravitational-wave finder scores again
New gravitational-wave finder scores again 15 June 2016Less than four months after the historic first-ever detection of gravitational waves, scientists on a team that includes Penn State University physicists and astronomers now have detected another gravitational wave washing over the Earth. "I would never have guessed that we would be so fortunate to have, not only one, but two definitive binary black-hole detections within the first few months of observations," said Chad Hanna, an assistant professor of physics and astronomy & astrophysics at Penn State and co-chair of the Compact Binary Coalescence Group of the Laser Interferometer Gravitational-wave Observatory (LIGO), which detected both the first gravitational wave and this new one since beginning observations last fall.
