Analysis of Quantum Correlation in Successive Spin Measurements, Classical Communication of Spin $S$ Singlet States and Quantum Nonlocality of two Qubit Entangled States

TL;DR

This paper investigates classical simulation of spin correlations, quantum correlations in sequential measurements, and nonlocality without inequalities in two-qubit entangled states, advancing understanding of quantum nonlocality and simulation.

Contribution

It introduces new methods for classical simulation of spin correlations, analyzes quantum correlations in successive measurements, and explores nonlocality without inequalities in two-qubit states.

Findings

Classical simulation of spin-$s$ correlations achieved for all $s$.

Quantum correlations observed in successive single spin measurements.

Nonlocality without inequalities demonstrated for most two-qubit entangled states.

Abstract

In this thesis, we study about three subjects 1- Classical simulation of two spin-$s$ singlet correlations for all $s$ involving spin measurements, 2- Quantum correlations in successive single spin measurements, 3- Non locality without inequality for almost all two-qubit entangled states based on Cabello's non locality argument.
