One of the most difficult obstacles to overcome in the quantum race will be the supply chain, given how diffuse it is, a top White House official said Wednesday.

“Supply chain is one of the biggest challenges in my mind, and really, the challenge with the quantum supply chain is that quantum is not defined by a single hardware platform,” said Brad Blakestad, director of the National Quantum Coordination Office within the White House Office of Science and Technology Policy.

“If you look at the quantum computing technologies, the quantum sensing technologies, the networking — those are all different,” he said in a webinar hosted by Inside Cybersecurity and USTelecom. “And even within computing, there’s seven different modalities that use completely different components. So we have this not just one monolithic supply chain, but just a bunch of different supply chains that are kind of intertwined in various ways.”

Blakestad made his remarks a little more than a month after President Donald Trump signed two executive orders on quantum computing. He referenced proposed ways to address the supply chain challenge in one of the orders.

“The other major issue or challenge that we face right now is that we’re on the cusp of quantum exploding from a commercialization perspective, but we’re not quite there yet,” he said. “So there’s not the funding, the revenue coming from large-scale quantum companies at this point to really make the supply chain as robust as you would want. So thinking about it from the government perspective, it’s just [that] there are too many places that I would want to bolster and not enough funding to do it.”

Blakestad touted steps to help that along such as the government buying widgets from a company that makes them to certain specifications, or prize challenges.

The quantum supply chain isn’t just diffuse in the United States, an International Institute for Strategic Studies policy paper noted Wednesday. It’s “inherently international: no single country dominates the supply chain, whether specialised materials, cryogenic equipment, hardware, software, fabrication or algorithms,” the authors, Dongyoun Cho and Maria Shagina, wrote.

And a March report from the Center for a New American Security identified strengthening the quantum supply chain as pivotal to the United States seizing the benefits of the technology, citing gaps in the U.S. supply chain and reliance on foreign suppliers such as China and Russia. 

Supply chain wasn’t the only obstacle Blakestad mentioned as looming large.

“The encryption challenge is a real challenge, and we want to make sure that we are aware of when quantum computers will ultimately get to a scale that they start having these sorts of implications and move as quickly as we can,” he said. “So, just by owning the technologies, by owning the workforce, by making the United States the place that people want to come to be on the cutting edge of this technology, I think that kind of addresses both of those issues, and that’s what makes it so critical.”

Another difficulty is measuring progress, Blakestad said: “It’s also very, very hard to benchmark, and to know that you’re actually doing what you’re supposed to, what you are intending to do.”

President Donald Trump signed two executive orders Monday to accelerate the federal government’s transition to post-quantum encryption and reprioritize government financing to support the domestic quantum computing industry. 

The orders, which CyberScoop first reported on last year, direct the government to throw its weight behind the quantum computing industry. They are part of a broader effort by the Trump administration to put its stamp on the development of another key emerging technology.

In May, the Department of Commerce announced letters of intent for more than $2 billion in federal financing incentives for nine quantum companies under the CHIPS and Science Act. Last year, the administration did something similar with its AI-focused executive orders and action plan that created special federal export programs for AI technology and equipment, directed federal agencies to mobilize federal financing tools to support the industry, and cut or curtail regulations that the administration said may impede domestic growth. 

Ahead of the signing, sources previewed details of those orders to CyberScoop. Per one of those sources, who spoke on condition of anonymity to discuss pending administration actions, a “whole of government approach is used to empower research and development into quantum computing, as well as quantum sensing [and other resources].”

They described the Trump administration’s attitude for propping up industry as “don’t let us miss out on prioritizing the feeders for the research or the development of quantum.” 

The second order requires federal civilian networks to adopt quantum-resistant encryption faster than the current 2035 deadline. The new encryption algorithms, vetted by the National Institute of Standards and Technology, will protect against future quantum computer attacks. 

Agencies that miss the new deadline must report to the Office of Management and Budget explaining why. 

On hand for the signing were Department of Energy Undersecretary for Science Darío Gil, Department of Commerce Secretary Howard Lutnick, National Cyber Director Sean Cairncross, Defense Secretary Pete Hegseth, Federal Chief Information Officer Greg Barbaccia, and Office of Science and Technology Policy Director Michael Kratisos.

Multiple executives from technology companies were also on hand for the order’s signing, complimentary of the government’s efforts in boosting the industry.

“IBM applauds the Administration for taking this important, timely step forward,” said IBM CEO Arvind Krishna in a statement. “Sound policy, sustained investment and public-private partnership are vital to sustaining U.S. quantum leadership and technological resilience. We’re proud to keep building on this foundation — strengthening U.S. competitiveness and bolstering national security as we shape the quantum future together.”

“At Google, we are proud of our sustained breakthroughs in quantum computing and post-quantum cryptography,” said Google President and Chief Investment Officer Ruth Porat. “Quantum computing is a transformational technology that can advance national security, drug discovery, energy solutions and more.”
