Research Summary

Bartek Czech uses quantum information as a language for reconstructing geometry in holography. His recent work moves beyond individual entanglement-entropy formulas and studies the global constraints that make holographic states geometrical, including entropy cones, entropy inequalities, entanglement wedge nesting, and erasure-correction properties. This is complemented by work on modular Berry phases, symplectic forms, reflected entropy, and boundary-bulk transport, where the question is not only what geometric quantity an information measure computes, but how the space of boundary states carries bulk geometric data.
