Idse Heemskerk, Donald Marolf, Joseph Polchinski, James Sully
TL;DR
This paper explores how bulk operators, including those behind black hole horizons, can be constructed in AdS/CFT, addressing the possibility of determining a black hole's interior state through dual CFT measurements.
Contribution
It introduces methods for constructing bulk operators inside AdS black holes and examines the implications for measuring states behind horizons via the dual CFT.
Findings
Bulk operators can be constructed inside AdS black holes.
Measurement in the dual CFT may reveal information about the black hole interior.
The paper discusses the limits of observing behind the horizon.
Abstract
We discuss the construction of bulk operators in asymptotically AdS spacetimes, including the interiors of AdS black holes. We use this to address the question "If Schrodinger's cat were behind the horizon of an AdS black hole, could we determine its state by a measurement in the dual CFT?"
