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…
Wave packets from the spectrum
ChunJun Cao, Oliver Friedrich, Marin Girard +2
The freedom to change Fock basis seems to ensure a minimum amount of locality in lattice theories in the following sense: If for $i…
An efficient algorithm to compute entanglement in states with low magic
ChunJun Cao, Gong Cheng, Tianci Zhou
A bottleneck for analyzing the interplay between magic and entanglement is the computation of these quantities in highly entangled quantum many-body magic states. Efficient extract…
