Bell Nonlocality

Bell nonlocality is a fundamental concept in quantum theory that states that measurements of physical systems do not reveal pre-existing properties, but rather create them. This phenomenon has been observed beyond any doubt in the last decades and has fundamental implications for the development of quantum technologies. This book provides a logical presentation of nonlocality and its applications, including its use for certification of quantum devices.

The field of quantum technologies has experienced a remarkable surge in recent years, largely thanks to the fundamental concept of Bell nonlocality. This concept has played a pivotal role in enabling the development of these technologies. Bell nonlocality is one of the most remarkable discoveries stemming from quantum theory. It asserts that in certain scenarios, measurements of physical systems do not merely reveal pre-existing properties; rather, the property emerges solely through the act of measurement. In 1964, John Bell demonstrated that the predictions of quantum theory are incompatible with the assumption that outcomes are predetermined. This phenomenon has been unequivocally observed over the past several decades. Even if quantum theory were to be replaced in the future, this observation would remain steadfast. Moreover, nonlocality possesses profound implications that extend beyond its fundamental nature. It is so specific that it can be utilized to create and certify reliable quantum devices.

This book presents a logical, rather than historical, exploration of nonlocality and its diverse applications. Part 1 begins with a comprehensive survey of the meaning and interpretations of Bell nonlocality, followed by a mathematical formalization of this phenomenon. Part 2 delves into the potential of using evidence of nonlocality for the certification of devices in quantum technologies. Part 3 further explores the extensions and consequences of nonlocality for the foundations of physics.

In conclusion, the development of quantum technologies has been greatly influenced by the concept of Bell nonlocality. This remarkable discovery has opened up new avenues for research and innovation in the field of quantum physics. By understanding and harnessing the power of nonlocality, we can continue to push the boundaries of what is possible in the world of quantum computing and communication.
