Superposition of Large Objects

Microscopic crystals or nanodiamonds are put into controlled quantum superposition: a lab test for collapse and gravity.

Open in the interactive tree →

Levitated particles in ultra-high vacuum at very low temperatures could be brought into superposition at ever larger masses. This would test collapse models directly and would be the starting point for gravity-mediated entanglement experiments.

What it brings

  • A decision between collapse models and other interpretations
  • A lab test of whether gravity can entangle objects (quantum gravity)
  • Ultra-precise sensors for acceleration and gravity
  • An understanding of the boundary between quantum and everyday worlds
