Complementarity and the unitarity of the black hole -matrix
Isaac H. Kim, John Preskill
Recently, Akers et al. proposed a non-isometric holographic map from the interior of a black hole to its exterior. Within this model, we study properties of the black hole -matr…
A new operator extension of strong subadditivity of quantum entropy
Ting-Chun Lin, Isaac H. Kim, Min-Hsiu Hsieh
Let be the von Neumann entropy of a density matrix . Weak monotonicity asserts that for any tripartite density matrix $ρ_{…
Circuit depth versus energy in topologically ordered systems
Arkin Tikku, Isaac H. Kim
We prove a nontrivial circuit-depth lower bound for preparing a low-energy state of a locally interacting quantum many-body system in two dimensions, assuming the circuit is geomet…
Concatenation Schemes for Topological Fault-tolerant Quantum Error Correction
Zhaoyi Li, Isaac Kim, Patrick Hayden
We investigate a family of fault-tolerant quantum error correction schemes based on the concatenation of small error detection or error correction codes with the three-dimensional…
Modular Commutators in Conformal Field Theory
Yijian Zou, Bowen Shi, Jonathan Sorce +2
The modular commutator is a recently discovered multipartite entanglement measure that quantifies the chirality of the underlying many-body quantum state. In this Letter, we derive…
Measurement as a shortcut to long-range entangled quantum matter
Tsung-Cheng Lu, Leonardo A. Lessa, Isaac H. Kim +1
The preparation of long-range entangled states using unitary circuits is limited by Lieb-Robinson bounds, but circuits with projective measurements and feedback (``adaptive circuit…
