"Grothendieck's Inequality, Quantum Entanglement, and Tsirelson's Bound."

Abstract: In this talk, we discuss Grothendieck's inequality (GI), which began as a functional analysis result, and its use in quantum mechanics and Einstein's "Hidden Variable Theory" (HVT). Using GI, we are able to disprove Einstein's HVT and we use the proof to get a strong lower bound on Grothendieck's constant $K_{G}^{ℝ}$.
