Quantum information recovery from a black hole with a projective measurement

R Li, J Wang - Physical Review D, 2024 - APS
We studied the Hayden-Preskill thought experiment with the local projective measurement.
Compared to the original model, the measurement is applied to the Hawking radiation that …

Generalized volume complexity in Gauss-Bonnet gravity: Constraints and phase transitions

X Wang, R Li, J Wang - Physical Review D, 2023 - APS
It has been proposed that quantum complexity is dual to the volume of the extremal surface,
the action of the Wheeler-DeWitt patch, and the spacetime volume of the patch. Recently, a …

High-fidelity information recovery from radiating black holes through random local projection

R Li, X Wang, K Zhang, J Wang - arXiv preprint arXiv:2309.01917, 2023 - arxiv.org
The unitary evaporation of black holes enables the potential retrieval of information from
Hawking radiation, leading to the development of explicit decoding protocols. However, the …
