Description
Summary:This letter introduces a unitarity-preserving holographic correspondence within a $d$-dimensional de Sitter (dS$_d$) spacetime, distinctly challenging the prevailing notion that the holographic framework of dS$_d$ falls short in maintaining unitarity. The proposed approach is rooted in the geometry of the complex dS$_d$ spacetime and leverages the inherent properties of the (global) dS$_d$ plane waves, as defined within their designated tube domains.
