Quantum Frontiers and Fundamentals, 2018

Ever since the advent of quantum mechanics during 1925–26, its fundamental conceptual issues continued to intrigue some of the best minds in physics like Einstein, Schrodinger, Louis de-Broglie, David Bohm and John Bell, giving rise to extensive searching debates. The celebrated Einstein–Podolsky–Rosen argument stimulated Schrodinger to bring out the importance of quantum entanglement as the ‘essential characteristic trait of quantum mechanics’. Subsequently, the seminal discovery of John Bell in 1964 of a theorem enabling empirical testing of the fundamental notions of locality and realism vis-a-vis quantum mechanical predictions paved the way for intimately linking the quantum foundational studies with actual experiments.
