The Schrödinger Institute was a deep-space research station.

The institute was the size of Oxford. It had an enormous chamber housing the accelerator. The rest of the station was cramped.

Tasdevin worked at the station, ostensibly on his project to find a perpetual-motion machine, but in reality he was trying to stabilise a small portion of space-time so that it would constantly recycle and he would never age. His experiment caused a temporal echo of the station in which the Doctor and Guinevere Winchester were caught. When they ended the echo, the Doctor theorised that the echo version of the station would wink out of space when they left it. (PROSE: Revenants)
