The Wanted Extension of Fujii and Tsurumaru’s Formula for the Spectral Radius of the Bell-CHSH Operator

Abstract This paper is motivated by a recent paper of Yuki Fujii and Toyohiro Tsurumaru in which they established a beautiful formula for the spectral radius of the Bell-CHSH operator on finite-dimensional Hilbert spaces. To tackle the operator on infinite-dimensional spaces, the...
