On October 25, 2023, Chairwoman Nancy Mace of the Subcommittee on Cybersecurity, Information Technology, and Government Innovation addressed attendees in a hearing on the implications of quantum computing for cybersecurity.
Her opening remarks focused on the urgency for the United States to prepare for the transformative impacts of quantum technology, especially concerning encryption and data protection.
Mace highlighted that while quantum computing may seem like a concept straight out of science fiction, it is very much a present-day reality with significant implications looming.
The chairwoman outlined how classical computing—what the public currently uses for devices like phones and laptops—differs fundamentally from the operations of quantum computers.
Classical computing is what powers current technology systems, from cloud-based software to IT infrastructure.
In contrast, quantum computing operates under principles derived from quantum physics, enabling the resolution of complex problems that classical computers cannot efficiently solve.
The potential applications for quantum computing are vast, encompassing fields ranging from drug discovery to advanced scientific research.
Nonetheless, alongside its possibilities, the rise of quantum computing raises critical risks, particularly to traditional encryption methods, which many currently consider secure.
Experts agree that a sufficiently advanced quantum computer could render existing cryptographic protections ineffective across various sectors, including finance, healthcare, and defense.
Chairwoman Mace pointed to the strategic threat posed by foreign adversaries who might employ a “steal now, decrypt later” approach, gathering sensitive data today with the anticipation of decrypting it in the quantum future.
This demonstrates the critical need for the federal government to proactively address the vulnerabilities that quantum computing introduces to national cybersecurity.
In response to these challenges, Mace has championed legislative efforts, notably the Quantum Computing Cybersecurity Preparedness Act, co-led with Representative Khanna, which became law in December 2022.
The legislation mandates that the federal government create and implement a strategy for transitioning to post-quantum cryptography, aimed at safeguarding federal technology.
Mace expressed the need for swift action in these endeavors, stressing that anticipation is key to maintaining security in the face of quantum advancements.
The chairwoman highlighted a 2023 McKinsey report that anticipates the quantum technology market could exceed $100 billion by 2040, underlining the competitive nature of the field and the necessity for the United States to be at the forefront.
In her remarks, she referenced the National Quantum Initiative Act, signed into law by President Donald Trump in 2018, as evidence of the U.S. commitment to leading in this critical area of technology.
The hearing served as a platform to hear from experts and agency representatives regarding steps being taken toward effectively implementing the legislation aimed at preparing the country’s cybersecurity infrastructure for the quantum age.
As conversations around quantum computing intensify, it becomes increasingly clear that the stakes are high for both national security and technological advancement.
