Quantum computers could expose sensitive data within years, says IBM scientist
Quantum computers, heralded for their unprecedented computational power, could soon possess the capability to breach the encryption systems that protect critical infrastructure, financial markets and personal bank accounts, according to a leading scientist.
Speaking to Yahoo Finance Future Focus, director of IBM Research at Zurich, Dr Alessandro Curioni, explained that quantum computers leverage subatomic particles for calculations, enabling them to perform tasks at speeds unattainable by today's traditional computers.
"As a result of the development of quantum computing, all our sensitive data will be exposed," Curioni said. The scientist then listed the types of sensitive data that could be in jeopardy, such as "healthcare data and financial data." He also warned that even digital signatures on contracts could be forged.
While the exact timeline remains uncertain, Curioni emphasised that once quantum computers achieve sufficient power, they will be capable of breaking current cryptographic technology. "We do know that a quantum computing machine, probably before the end of the decade, will be powerful enough to break the standard cryptographic technology that is used today," he noted.

This looming event, known as 'Q-Day,' signifies the moment when quantum computers can crack cryptographic keys. These keys are complex codes used to secure data, ensuring it remains accessible only to authorised users. The implications of such a breach are profound, threatening personal banking information, financial systems and national security by exposing protected government and infrastructure data.
Global race for quantum supremacy
Curioni pointed out that the race to develop the first powerful quantum computer is fierce, with significant investments from nations worldwide.
When pressed on where in the world the first powerful quantum computer that can crack cryptographic technology could come from, Curioni said: "it could come from any nation that invests enough in the development of this technology."

He cited a report that said out of all the nations vying to win the race for quantum computing supremacy, "two countries show exponential investment in this area, the United States and China, where most of the developments are happening."
The Monetary Authority of Singapore (MAS) has also alerted financial institutions about the potential cybersecurity risks that quantum computing could introduce. Recent data shows that 95% of respondents believe quantum computing will significantly impact cryptographic security, yet only 25% of firms are addressing this threat.
Despite the looming risks, IBM (IBM) is proactively developing solutions to safeguard current systems. Curioni highlighted the creation of Quantum-Safe cryptographic algorithms designed to withstand quantum computer attacks. These advancements are part of a broader effort to ensure data security in the quantum era.
Quantum computing potential
Beyond the security concerns, Curioni highlighted the transformative potential of quantum computing. He described it as one of two major computing advancements this decade, alongside artificial intelligence. He described how quantum computing is poised to revolutionise various fields, including drug discovery, materials science and logistics optimisation.

"Quantum computing will allow us to revolutionise how scientists simulate nature, enabling better material design and drug discovery. This could lead to the development of new antibiotics or novel treatments for currently incurable diseases," Curioni said.
Additionally, quantum computing's ability to solve complex optimisation problems could significantly enhance logistics and financial operations.
Quantum computing and AI
The most exciting prospect, according to Curioni, lies in the synergy between quantum computing and machine learning.
This combination is expected to drive the most significant societal impact, leveraging the strengths of both technologies to advance numerous sectors and improve global problem-solving capabilities.
