This book explores the dynamically developing areas of quantum computing and quantum cryptography. The book offers an in-depth examination of the possibilities and difficulties presented by these revolutionary technologies, with the goal of connecting abstract ideas with real-world applications. The book is an extremely helpful resource in the context of the upcoming quantum age. This highlights the importance of creating cryptographic techniques that can withstand the power of quantum computers to protect digital communications and vital infrastructures. This work makes a substantial contribution to the topic of cybersecurity by doing a comprehensive analysis of classical and quantum cryptography approaches, as well as actual implementations and performance evaluations. The book plays a vital role in providing valuable guidance to researchers, practitioners, and policymakers. It offers valuable insights that are necessary for effectively managing the shift towards quantum-secure technology and safeguarding the future security of digital information.

Valentin BARNA is currently Full Professor at the Faculty of Physics, University of Bucharest, Romania. The academic background includes mainly classical mechanics, optics (LASERS, fluorescent materials) and photonics; physics of liquid crystals and LCD/OLED displays (electro-optics, microscopy); polymer physics (thin films, micro/nano structures and systems etc.); nanotechnologies; educational physics. The continuous searching for knowledge and new challenges is a priority, while also focusing on improving the technological and fundamental base of scientific information with novel discoveries and enhanced properties/characteristics of existing results. Prof. BARNA demonstrated that he could put to good use the scientific ideas either individually or by engaging in favorable collaborations with other international research groups (CASE Western Reserve University (USA), University of Calabria (Italy), K.I.T (Germany) etc).
