Artur Ekert: Pioneer of Quantum Cryptography and Quantum Computing

Further information in german at: https://schneppat.de/artur-konrad-ekert/ Artur Ekert is considered one of the leading pioneers in quantum information technology — a discipline that has revolutionized the foundations of cryptography, computer science, and quantum physics. With his groundbreaking concept of quantum cryptography based on particle entanglement, Ekert introduced an entirely new security architecture for digital communication in the early 1990s. His proposal for a quantum-secured key exchange — known as the E91 protocol — was not only technically innovative but also philosophically profound: it connected physical principles such as non-locality and causality with practical applications in IT security. However, Ekert’s influence goes far beyond cryptography. As a creative mind and interdisciplinary thinker, he has actively contributed to the development of quantum computers — machines that transcend classical information processing by harnessing fundamental processes of nature to solve computational problems more efficiently. In his numerous scientific publications, Ekert combines quantum physics with theoretical computer science, philosophy, and even ethics, to explore the implications of these technologies for science and society. Through professorships and research positions at renowned institutions such as the University of Oxford and the Centre for Quantum Technologies in Singapore, Ekert has inspired a new generation of quantum scientists. His impact is felt not only in academic research but also in political and industrial strategies related to quantum technology — from global cybersecurity to the next generation of computers and sensors. This introduction highlights Artur Ekert’s most significant innovations and illustrates why his ideas represent not only technological breakthroughs but also intellectual impulses for the 21st century.
