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…

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…

Constraint on cosmological constant in generalized Skryme-teleparallel system
Krishnanand Karthikeyan, Mathew Thomas Arun
The Einstein-Skyrme system is understood to defy the "no hair" conjecture by possessing black-hole solutions with fractional baryon number outside the event horizon. In this articl…
