We were trying to find a material that would be a thermal insulator at extremely low temperatures, yet would be relatively strong.

While it's unlikely that Lego blocks per se will be used as a part of a quantum computer, we've found the right direction for creating cheap thermal insulators : 3D printing, the Lego is made from ABS plastic and one can also create ABS structures simply by 3D printing them. We are currently studying the properties of such 3D printed structures at ultralow temperatures close to absolute zero.
