Christoph Becher on the Physical Principles, Technological Challenges and Security Aspects of Quantum Computing –
The podcast “Irgendwas mit IT” brings together the perspectives of the six Security-Insider publications BigData-Insider, CloudComputing-Insider, DataCenter-Insider, IP-Insider, Security-Insider, and Storage-Insider, featuring experts discussing a wide range of topics. The third episode focuses on Quantum Computers. In this episode, Security-Insider editor Melanie Staudacher talks to Prof. Dr. Christoph Becher from the Quantum Optics Research Group at Universität des Saarlandes (UdS) about the mathematical and physical foundations of Quantum Computers, the physical implementation of qubits and the security-related aspects of Quantum Computing. The discussion covers not only the potential and technical challenges of this technology, but also possible approaches to addressing the threat that powerful Quantum Computers pose to certain encryption methods currently in use. The focus is on Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD). The conversation also addresses why Quantum Repeaters are needed to transmit Quantum States over longer distances.
In addition to the conversation with Christoph Becher, the podcast features two additional interviews featuring Dr. Florian Preis and Dr. Jan Schnabel. Florian Preis is Vice President of Quantum Brilliance, a world-leading company in the field of diamond-based Quantum Technologies. In his conversation with DataCenter-Insider editor Daniel Schrader, he discusses potential applications of Quantum Computers, their interference properties, as well as technical bottlenecks and the challenges posed by noisy systems. Jan Schnabel, Group Leader at the Fraunhofer-Institut für Produktionstechnik und Automatisierung IPA, talks to CloudComputing-Insider editor-in-chief Elke Witmer-Goßner about how companies could use Quantum Computers as a service via the cloud in the future.
Schnabel’s words aptly sum up the podcast’s key message: “Ultimately, Quantum Computers will not replace classical computers, but rather complement them in specific computational problems.” Click here for the podcast.
