As published in the journal Quantum Insider on March 11, the U.S. Defense Advanced Research Projects Agency (DARPA) has launched a new recruitment effort to incorporate organizations with quantum architectures not yet evaluated by the agency.
The goal of this research, part of DARPA’s Quantum Assessment Initiative (QBI), is to determine if there is any approach. Quantum computers of useful scale could be built by 2033 That is, a machine whose actual computational value exceeds the operating cost threshold that DARPA considers the tipping point toward commercialization of the technology.
Since its inception in mid-2024, the QBI program has evaluated 20 commercial organizations with different qubit architectures. Eleven companies have progressed to ‘Stage B’, which focuses on technical risk mitigation and development planning, and two have reached ‘Stage C’. They work with governments to verify and verify operations At the system level, as specified in the aforementioned journals.
The new calls are specifically targeted at architectures that were not evaluated in the previous stage.
Interested organizations must submit abstracts by July 31, 2026, and complete proposals by September 30. Selected companies will enter Stage A for six months, where they will have to explain their complete system concept and provide technical evidence of its feasibility.
In conjunction with this call, DARPA announced a change in leadership. Mika Stoutimore will replace founder Joe Altepeter as program director.
Stoutimore’s text “It is highly likely that someone will build a quantum computer at a useful scale by 2033.”However, it is not yet clear which team will cross that goal line,” he declared.
When QBI was launched in 2024, the central question was whether it was technically possible to reach that threshold. The new manager thinks that is likely.
Meanwhile, DARPA, founded in 1958, is the advanced research arm of the U.S. Department of Defense and has been responsible for developing technologies that have defined the United States’ global military and technological leadership, including precursors to the Internet such as the famous ARPANET. Direct involvement in the quantum race is therefore a sign that Washington is assigning strategic importance to this technology.
What does it mean to achieve useful scale for digital security?
A “practical scale” quantum computer like the one Stouttimore proposed would not automatically equate to machines that can break the codes that secure Bitcoin, global digital communications, and banking systems.
However, recent advances have narrowed that perspective. As reported by CriptoNoticias, the Iceberg Quantum company announced its Pinnacle architecture in February. Fewer physical qubits needed to crack RSA-2048 encryption The number of people affected has gone from between 2 million and 20 million to just 100,000, one-tenth of previous estimates.
RSA-2048 is a standard widely used today to secure most communications on the Internet, from banking connections to digital signatures, and that’s where the experiments conducted by Iceberg Quantum are relevant.
That same month, French researchers published a study that reduced the quantum resources needed to compromise elliptic curve cryptography (ECC), the system that builds Bitcoin’s security, by 48%. 2,124 logical qubits to between 1,098 and 1,193.
None of these studies indicate that “Q-Day,” the moment when quantum computers can break current cryptographic systems, is imminent. However, both confirm that the technological threshold for achieving this is falling faster than industry expectations.
Furthermore, quantum computing is not limited to offensive possibilities against cryptographic systems.
In parallel, companies such as IonQ and Microsoft are proposing a combination of quantum computing and artificial intelligence (AI) to accelerate the discovery of new materials and chemical reactions. Medical, energy, and environmental applications. From more effective drugs and cleaner batteries to catalysts that capture carbon from the atmosphere.
The same technologies that have the potential to compromise global digital security also have the potential to solve some of today’s most complex scientific problems.
US sets sights on developing quantum computing
DARPA’s announcement comes against the backdrop of the growing relationship between quantum computing and the U.S. government.
As reported by CriptoNoticias, on February 23, IonQ, a leading quantum development company, was selected as a participant in the US Missile Defense Agency’s SHIELD IDIQ contract. Budget cap is up to $151 billion.
The selection of IonQ and other institutions confirms that the U.S. federal government is not only announcing a quantum strategy, but actively funding its development.
Similarly, the Trump administration released its National Cybersecurity Strategy on March 6th. National security priorities included the adoption of post-quantum cryptography.
