Do you remember the famous quantum corrals? (see figure below)
Well, lets say that Prof. Thomas A. Jung and co-workers have gone way further than that. During 2016, they presented a quantum breadboard, composed of a 2D metalorganic network creating surface state derived quantum well states in the pores. Scanning probe microscopy manipulation of Xe atoms was used to configure the Xe population of the pores, which affects the quantum state of the 2D array or breadboard.
