The Grasshopper Problem on the Sphere
David Llamas, Dmitry Chistikov, Adrian Kent +2
The spherical grasshopper problem is a geometric optimization problem that arises in the context of Bell inequalities and can be interpreted as identifying the best local hidden va…
Optimal Local Simulations of a Quantum Singlet
David Llamas, Dmitry Chistikov, Adrian Kent +2
Bell's seminal work showed that no local hidden variable (LHV) model can fully reproduce the quantum correlations of a two-qubit singlet state. His argument and later developments…
Globe-hopping
Dmitry Chistikov, Olga Goulko, Adrian Kent +1
We consider versions of the grasshopper problem (Goulko and Kent, 2017) on the circle and the sphere, which are relevant to Bell inequalities. For a circle of circumference , w…
