Will Quantum Computers Become the Next Cyber-Attack Platform?

The security of today’s public key encryption is based on the fact that huge computational resources are required to solve factoring problems, especially for large integers, says NTT Research CEO, Kazuhiro (Kazu) Gomi. This may no longer be true in the years ahead, he warns. “Shor’s algorithm, running on a scalable quantum computer, will change …

18 New And Emerging Biotech Developments Everyone Should Know About

Autonomous therapeutic systems are one of the most significant future medical technologies. These systems take over patient care from (human) providers by analyzing, determining and autonomously controlling conditions and treatments. Thus, we need to have a precise simulation of a patient’s medical condition—the patient’s bio digital twin. This should reduce human error and medical care …

Machine-learning system based on light could yield more powerful, efficient large language models

MIT system demonstrates greater than 100-fold improvement in energy efficiency and a 25-fold improvement in compute density compared with current systems. The current work is the latest achievement in a drumbeat of progress over the last few years by Englund and many of the same colleagues. For example, in 2019 an Englund team reported the …
