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.…

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…
