Entanglement-enhanced optomechanical sensor array for dark matter searches

Understand

The nature of dark matter is one of the most important open questions in modern physics.

• The search for dark matter is challenging since, besides gravitational interaction, it feebly interacts with ordinary matter.
• Mechanical sensors are one of the leading candidates for dark matter searches in the low frequency region.
• Here, we propose entanglement-enhanced optomechanical sensing systems to assist the search for DM with mechanical sensing devices.
