For this issue, we asked our experts to discuss the automotive electronics market and what all of these changes mean for PCB designers, design engineers, and product developers. In our experts interview, Edi - tor Dan Feinberg reviews the evolution of AI, autonomous cars, and electric vehicles, including what he's seen in years of covering CES for his column. Zuken's Humair Manda - via discusses the company's EDA tools and focus on the automotive electronics market. Thomas Wischnack of Porsche Engineering Services explains how Porsche approaches PCB and hardware development, and offers tips for new PCB designers. James McLeish of DfR Solutions highlights his company's high-reliability test software that is used by automotive electronics developers. Next, Tarun Amla of ITEQ discusses ITEQ's focus on developing PCB materials for autonomous and electric vehicles, as well as 5G technology. Pete Christiansen of Magi Scitech shows us the company's new graphene heat sink, which offers thermal management capabilities for automotive and household electronics. And EDADOC's William Zhou and Wen Ling discuss their longtime design of automotive PCBs, which has made the company one of the biggest forces in the automotive electronics indus - try in China. Automotive electronics is evolving, almost daily, and there's a lot of confusion. Some- times it's difficult to get an accurate snap- shot of where we are technologically in this segment. At Design007 Magazine, we'll keep our ear to the ground so we can bring you the latest in the technologies of today and tomorrow. See you next month! DESIGN007 Physicists Reveal Material for High-Speed Quantum Internet Researchers from the Moscow Institute of Physics and Technology have "rediscovered" a material that can lay the foundation for ultrahigh-speed quantum internet. Their paper published in npj Quantum Information shows how to increase the data transfer rate in uncondition- ally secure quantum communication lines to more than 1 gigabit per second, making quantum internet as fast as its classical counterpart. The greatest expectation about the quantum com- puter is that it could break the security of all classical data transfer networks. Today, sensitive data such as personal communication or financial information are protected using encryption algorithms that would take a classical supercomputer years to crack. A quantum com- puter could conceivably do this in a few seconds. Photons are the best carriers for quantum bits. The principle of single-photon generation is quite simple: An excited quantum system can relax into the ground state by emitting exactly one photon. This process is at the heart of the electrically driven single-photon source. Using their theory, the research- ers have shown how a single-photon emitting diode based on silicon carbide can be improved to emit up to several billion photons per second. That is exactly what one needs to implement quantum cryptography proto- cols at data transfer rates on the order of 1 Gbps. This makes silicon carbide by far the most promising material for building practical ultrawide-bandwidth uncondition- ally secure data communication lines.
