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…
Observation of gravity-like signatures in holographic codes on a quantum computer
Debopriyo Biswas, Gong Cheng, Krishnanand Karthikeyan +12
The unification of quantum mechanics and general relativity remains one of the major open problems of theoretical physics. The Anti-de Sitter/Conformal Field Theory (AdS/CFT) corre…
Demystifying Objectivity with Operator Algebra Quantum Error Correction
Marin Girard, Gong Cheng, ChunJun Cao
Quantum Darwinism extends the decoherence formalism to explain how objectivity emerges from quantum mechanics. However, existing approaches often capture only partial aspects of ob…
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…
