Approximate locality, black hole complementarity and overlapping qubits
ChunJun Cao, Gong Cheng, Alexander Jahn +1
We construct a toy model of an evaporating black hole using approximately local degrees of freedom acting on ``overlapping" qubits in which a version of black hole complementarity…
End-of-the-World Singularities: The Good, the Bad, and the Heated-up
José Calderón-Infante, Gongrui Cheng, Alvaro Herráez +1
We revisit codimension-one End-of-the-World curvature singularities that drive scalars to infinite distance in field-space and have appeared in the context of dynamical cobordisms.…
State-dependent geometries from magic-enriched quantum codes
ChunJun Cao, Gong Cheng, Krishnanand Karthikeyan +2
Quantum error-correcting codes provide a powerful framework for emergent spacetime, yet existing subsystem erasure-correcting holographic code models describe only quantum fields o…
Gravitational back-reaction is magical
ChunJun Cao, Gong Cheng, Alioscia Hamma +3
We study the interplay between magic and entanglement in quantum many-body systems. We show that non-local magic, which is supported by the quantum correlations is lower bounded by…
Holographic phenomenology via overlapping degrees of freedom
Oliver Friedrich, ChunJun Cao, Sean M. Carroll +2
The holographic principle suggests that regions of space contain fewer physical degrees of freedom than would be implied by conventional quantum field theory. Meanwhile, in Hilbert…
