Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers.
With this, the international research team has also made an important step towards practical applications such as a future quantum internet, since high-dimensional quantum systems can transport larger amounts of information than qubits. “This result could help to connect quantum computers with information capacities beyond qubits”, says Anton Zeilinger, quantum physicist at the Austrian Academy of Sciences and the University of Vienna, about the innovative potential of the new method.
The participating Chinese researchers also see great opportunities in multidimensional quantum teleportation.
Early this year, we posted on a rumour that Windows Lite may come without support for Microsoft’s Live Tile system. Later, we reported another evidence indicating that Live Tiles may soon disappear on Windows 10 Start Menu. Today, the death of Live Tiles was almost confirmed, thanks to the new internal build which Microsoft released accidentally. […]
Fernando Corbató, whose work on computer time-sharing in the 1960s helped pave the way for the personal computer, as well as the computer password, died on Friday at a nursing home in Newburyport, Mass. He was 93.
His wife, Emily Corbató, said the cause was complications of diabetes. At his death he was a professor emeritus at the Massachusetts Institute of Technology.
Dr. Corbató, who spent his entire career at M.I.T., oversaw a project in the early 1960s called the Compatible Time-Sharing System, or C.T.S.S., which allowed multiple users in different locations to access a single computer simultaneously through telephone lines.
At the time, computing was done in large batches, and users typically had to wait until the next day to get the results of a computation.

Americans are becoming increasingly sedentary, spending almost a third of their waking hours sitting down, and computer use is partly to blame, a new study found.
Over almost a decade, average daily sitting time increased by roughly an hour, to about eight hours for U.S. teens and almost 6 1/2 hours for adults, according to the researchers. That includes school and work hours, but leisure-time computer use among all ages increased too.
By 2016, at least half of American kids and adults spent an hour or more of leisure time daily using computers. The biggest increase was among the oldest adults: 15% of retirement-aged adults reported using computers that often in 2003-04, soaring to more than half in 2015-16.
