A new progress in the scaling of semiconductor quantum dot based qubit has been achieved at Key Laboratory of Quantum Information and Synergetic Innovation Center of Quantum Information & Quantum Physics of USTC. Professor GUO Guoping with his co-workers, XIAO Ming, LI Haiou and CAO Gang, designed and fabricated a quantum processor with six quantum…

A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys during the passage of the satellite Micius over a ground station. Using Micius as a…
