Tool sketches quantum circuits

Researchers from Cambridge University in England and the Massachusetts Institute of Technology have developed a lithographic technique, dubbed erasable electrostatic lithography, that allows a quantum device to be drawn in a few hours rather than a couple of weeks. The researchers have used the method to define quantum wires, dots and hills, and are currently working on improving the technique's resolution, according to the researchers.
