Non-isometry, State Dependence and Holography
Stefano Antonini, Vijay Balasubramanian, Ning Bao +2
We establish an equivalence between non-isometry of quantum codes and state-dependence of operator reconstruction, and discuss implications of this equivalence for holographic dual…
Non-trivial Area Operators Require Non-local Magic
ChunJun Cao
We show that no stabilizer codes over any local dimension can support a non-trivial area operator for any bipartition of the physical degrees of freedom even if certain code subalg…
Overlapping qubits from non-isometric maps and de Sitter tensor networks
ChunJun Cao, Wissam Chemissany, Alexander Jahn +1
We construct approximately local observables, or "overlapping qubits", using non-isometric maps and show that processes in local effective theories can be spoofed with a quantum sy…
More of the Bulk from Extremal Area Variations
Ning Bao, ChunJun Cao, Sebastian Fischetti +2
It was shown recently, building on work of Alexakis, Balehowksy, and Nachman that the geometry of (some portion of) a manifold with boundary is uniquely fixed by the areas of a fol…
Building Bulk Geometry from the Tensor Radon Transform
ChunJun Cao, Xiao-Liang Qi, Brian Swingle +1
Using the tensor Radon transform and related numerical methods, we study how bulk geometries can be explicitly reconstructed from boundary entanglement entropies in the specific ca…
How Low Can Vacuum Energy Go When Your Fields Are Finite-Dimensional?
ChunJun Cao, Aidan Chatwin-Davies, Ashmeet Singh
According to the holographic bound, there is only a finite density of degrees of freedom in space when gravity is taken into account. Conventional quantum field theory does not con…
