Summary
- Leaders in the quantum sector believe Trump's executive actions could bolster U.S. dominance.
- Experts noted that the updated timelines align more closely with advancements in quantum technology.
- Bitcoin is under increasing pressure to adapt to a future influenced by quantum computing, yet efforts are still nascent.
President Donald Trump's recent executive orders aimed at fast-tracking the U.S. government's shift to post-quantum cryptography by 2031 have sparked both approval and skepticism from experts, who assert that the federal plans are adjusting to the swiftly evolving quantum landscape.
The executive orders signed on Monday revise the federal deadline for adopting post-quantum cryptography from 2035 to 2031, coinciding with increased efforts from governments, tech firms, and cryptocurrency developers to brace for potential quantum threats.
Dr. Stefan Leichenauer, vice president of engineering and lead scientist at SandboxAQ, remarked, "Predicting an exact timeline for a cryptographically relevant quantum computer is challenging due to numerous uncertainties, but a window of three to ten years seems plausible. The critical aspect is that the implications of such a computer are so severe that we must prepare for the most aggressive scenarios."
He cautioned, however, that many organizations may already be lagging in their transition to post-quantum cryptography. "We are making progress on this migration, yet the lengthy transition periods for numerous systems suggest we might be behind schedule. The shift to post-quantum computing is a multi-year endeavor, and it's likely a cryptographically relevant quantum computer will emerge before we complete it," Leichenauer added. He emphasized that the executive orders should act as "a wake-up call," stressing the urgency of quantum security.
Alex Pruden, CEO of quantum security firm Project Eleven, expressed that the revised timeline from the White House was overdue. "There has been increasing chatter about advancements in quantum computing, and other nations have updated their timelines, with France being the latest to do so," Pruden told Decrypt. "When I saw this order, I thought it was a good move—finally!"
While Pruden views the 2028 deadline as ambitious, he no longer considers it impossible. Project Eleven assesses a 50% likelihood of encountering a cryptographically relevant quantum computer by 2033, and a 10% chance by 2030. "If you had asked me two years ago, I would have said there was a 0% chance. Now, I believe there's a significant possibility," he said.
Paul Stimers, a partner at Holland & Knight and executive director of the Quantum Industry Coalition, noted that the executive orders reflect a growing consensus on the diminishing timeline for a cryptographically relevant quantum computer. "Roadmaps in the quantum industry are aligning around the 2028-2030 timeframe," Stimers stated. However, he warned that public projections might not account for classified quantum computing initiatives within the U.S. or abroad.
He highlighted a pressing concern that adversaries are currently gathering encrypted data in anticipation of future decryption capabilities. "Since adversaries are already stealing encrypted data and saving it until they can decrypt it with a cryptographically relevant quantum computer, the threat is immediate, and the time to act is now," he explained. "Transitioning to post-quantum encryption and agile cybersecurity is a time-consuming process. The cybersecurity executive order balances urgency with realism."
Stimers mentioned that coalition members have reacted positively to the executive orders, praising their emphasis on manufacturing, commercialization, deployment, and industry collaboration alongside research. He described the administration's roadmap for post-quantum cybersecurity as ambitious yet achievable.
However, not everyone perceives the executive orders as a proactive step by the government. Some critics on social media argued that the urgency surrounding post-quantum cryptography is long overdue, as sensitive data is already being collected and stored in anticipation of future quantum computers being able to decrypt it.
Others, including quantum physicist Anastasia Marchenkova, noted that while the administration's focus on "quantum dominance" is helpful in raising awareness and attracting investment, it might also foster unrealistic expectations about how quickly the industry can yield practical outcomes. Marchenkova remarked, "Integrating 'quantum' into the national dialogue genuinely helps—funding, interest, and new talent entering the field are crucial for transitioning from research to commercialization and creating tangible businesses. However, readiness is often unexciting and unglamorous: it involves agility, migration, and actually delivering defense solutions, rather than merely promoting the potential to break encryption or build a quantum computer."
"If deadlines slip—and some will—the skeptics will become more vocal," she added. "With the advent of public quantum companies, these announcements significantly impact the market, even though the long-term consequences remain uncertain."
Despite these concerns, Marchenkova stated that there is nothing fundamentally wrong with the executive orders. "What's lacking is clarity on the 'how.' We now have multiple standardized post-quantum algorithms, yet there’s confusion about which to apply in various scenarios and which is optimal. The order instructs to 'migrate,' but doesn't specify 'here's how to choose.'"
Christopher Tam, president and innovation head at BTQ Technologies, criticized the administration's 2031 deadline for federal agencies to transition high-value assets to post-quantum cryptography as being too slow given the rapid pace of industry advancements and the risks posed by quantum computing. "I would have made it more urgent," Tam stated to Decrypt, highlighting that companies like Google have already set 2029 goals for post-quantum migration. "It seems odd that the federal government would trail behind the industry by two years."
Tam also criticized the limited scope of the order, noting that it primarily addresses federal systems while leaving much of the financial sector and broader industrial base outside its immediate purview. Nevertheless, he acknowledged the administration's effort in linking quantum computing and cybersecurity initiatives in separate but related executive orders. "Advancements in quantum computing research and their successful development carry with them the risk of quantum cryptographic attacks," Tam explained. "That's why we witnessed these two executive orders being issued in tandem."
For cryptocurrencies, the situation is more complex. While regulators can influence banks and financial institutions, decentralized networks like Bitcoin cannot be steered by executive action. "You can't issue an executive order for Bitcoin," he noted. "There’s no entity to respond to that."
Bitcoin's Coordination Challenge
The executive orders come at a time when the cryptocurrency sector is contemplating how to transition to quantum-resistant security measures. In March, BTQ Technologies introduced a Bitcoin test network based on the quantum-resistance proposal BIP-360. In April, developers released BIP-361, a proposal aimed at freezing Bitcoin held in vulnerable legacy addresses if owners fail to upgrade to quantum-resistant options. Meanwhile, developers from networks like Stellar and Algorand have published roadmaps for integrating quantum-resistant cryptography.
Pruden noted that while awareness of the quantum threat has surged over the past year, tangible progress on implementing solutions remains limited. Unlike many blockchain networks, Bitcoin lacks a governing body or foundation capable of orchestrating a migration effort. Therefore, any transition would necessitate collaboration among developers, miners, exchanges, custodians, and major stakeholders. "Awareness has reached where it needs to be, but now there's a pressing question of what actions are being taken," Pruden concluded.
