In Stuart Fails to Save the Universe, the quantum-interference device is called the vari-state quantum interference device, also described as an experimental quantum entanglement device.

What It Is & What It Does
- The device was created by Sheldon Cooper, Leonard Hofstadter, and Howard Wolowitz at Caltech. 2. Its malfunction is what causes multiverse Armageddon—splitting reality into parallel universes and triggering catastrophic dimensional instability. 3. Stuart accidentally damages or breaks it, which sets in motion the quest to repair it and restore the correct reality.
If you want, I can dig up more about how the device is supposed to be fixed or what mechanisms are supposed to reverse its damage.
