The proposed research project aims to write a new chapter in the history of quantum physics, adopting a transnational perspective and shifting the still-predominant scholarly focus on theoretical revolutions and philosophical debates of the first half of the 20th century towards the materiality of experiments aimed at controlling quantum phenomena. Within the scope of CTRL-Q, we will specifically analyze the instruments, materials, and facilities used in experimental quantum physics during the second half of the 20th and early 21st century, including the advent of new interdisciplinary research fields in science and technology intersecting with physics towards the end of the 20th century, such as quantum cryptography, quantum computing, and quantum sensing. With CTRL-Q, we will establish a new international research network to foster and train a new generation of historians of quantum physics, building an active and globally connected research community with the long-term objective of investigating the history of quantum control through the lens of material culture.
