In 2019, Google's announcement in Nature about the development of the quantum computer Sycamore marked a significant milestone in computational technology. Sycamore demonstrated the capability to perform a task in 200 seconds, which would have taken 10,000 years using existing supercomputers. This breakthrough is attributed to quantum computers' utilization of overlapping qubits, enabling superior performance over classical computers in certain algorithmic tasks. However, this advancement poses a significant challenge to current encryption systems, which are vulnerable to breaches by quantum computers. The emergence of quantum cryptography communication (QCC) is a direct response to the security threats posed by quantum computers. QCC, incorporating Quantum Key Distribution (QKD) and Post Quantum Cryptography (PQC) technologies, offers a secure method of communication impervious to the hacking capabilities of quantum computers. It is becoming increasingly vital in sectors where security is paramount, such as government, autonomous vehicles, finance, healthcare, mobile communications, and the military. Despite active research in the technical aspects of QCC, there is a lack of studies exploring its social science dimensions, such as acceptance, adoption, and intention to implement. This study addresses this gap by empirically investigating the factors influencing the adoption of QCC. Drawing from previous research, it identifies variables related to the unique characteristics of quantum cryptography, as well as organizational, environmental, and technological factors. The study proposes a model based on performance expectancy and effort expectancy. Its academic significance lies in being the first empirical study focused on quantum cryptography. Theoretically, it underscores the crucial impact of QKD and PQC technologies - the core of quantum cryptography - on their acceptance and industry competitiveness.
