Spacetime from Unentanglement

Understand

The past decade has seen a tremendous effort toward unraveling the relationship between entanglement and emergent spacetime.

• These investigations have revealed that entanglement between holographic degrees of freedom is crucial for the existence of bulk spacetime.
• We examine this connection from the other end of the entanglement spectrum and clarify the assertion that maximally entangled states have no reconstructable spacetime.
• To do so, we first define the conditions for bulk reconstructability.
