Quantum boxes

Do you remember the famous quantum corrals? (see figure below)

The Well (Quantum Corral) (2009) by Julian Voss-Andreae. Created using the 1993 experimental data by Lutz et al., the gilded sculpture was pictured in a 2009 review of the art exhibition

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.
