"Exotic Quantum States in Circuit QED Systems"

  • Nov 1--2, 2012
  • Hogil Kim Memorial Building Room 512, POSTECH, Pohang, Korea
Asia-Pacific Center for Theoretical Physics (APCTP)

Recently, there have been strong activities in the field of quantum states of circuit QED system. Supposedly, the circuit QED system is one of the two most promising candidates for the solid-state based quantum information processing -- the other is the diamond NV center. At this workshop we will see why.

This workshop is supported by the APCTP.
