On this week's episode of Yahoo Finance Future Focus, our host Brian McGleenon speaks with Dr. Alessandro Curioni, Director of IBM Research at Zurich, about the transformative and potentially perilous future of quantum computing. Highlighting their unparalleled computational power, Curioni explains how quantum computers use subatomic particles to perform calculations at unprecedented speeds. However, he warns that these advancements could soon enable quantum computers to breach the encryption systems safeguarding critical infrastructure, financial markets, and personal bank accounts. "As a result of the development of quantum computing, all our sensitive data will be exposed," Curioni states. He outlines the potential risks to healthcare, financial data, and even digital contract signatures. Despite an uncertain timeline, Curioni asserts that by the end of the decade, quantum computers will likely be able to break current cryptographic technologies. This critical moment, referred to as "Q-Day," signifies when quantum computers can crack cryptographic keys, posing profound risks to personal banking information, financial systems, and national security. Curioni also discusses the global race to develop the first powerful quantum computer, with the United States and China leading the charge due to their significant investments...
