(Phys.org)—When it comes to fabricating complex quantum devices, one limitation is the number of wires available on the measurement systems that the quantum devices are built on. Typically, controlling just three or four ...
(Phys.org)—The question of what a computer is capable of, and what it is not, has intrigued computer scientists since the 1930s, when Alonzo Church and Alan Turing began investigating the capabilities and limits of computers. ...
(PhysOrg.com) -- Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices.
