IBM has announced at this year's American Physical Society meeting that its System Q One quantum computer has reached its "highest quantum volume to date"—a measure that the computer has doubled in performance in each of ...
A research team lead by Osaka University demonstrated how information encoded in the circular polarization of a laser beam can be translated into the spin state of an electron in a quantum dot, each being a quantum bit and ...
