DOE Reinvests $125 Million in the Argonne-Led Q-NEXT Quantum Centre
Funding for Q-NEXT, a National Quantum Information Science Research Centre (NQISRC), has been renewed by the U.S. Department of Energy (DOE), guaranteeing its continuous operation for an additional five years. Five NQISRCs have been awarded continued funding, including Q-NEXT, which is led by Argonne National Laboratory in collaboration with SLAC National Accelerator Laboratory.
Over the next five years, DOE has allocated $125 million to Q-NEXT. The goal of this initiative is to develop the necessary skills for connecting quantum technology over short and long distances. $25 million of the renewal funds are set aside for fiscal year 2026; out-of-year financing is contingent on congressional appropriations. In all, DOE announced $625 million for the renewal of its five NQISRCs.
The United States’ standing as a world leader in the revolutionary field of quantum information science and technology is cemented by this dedication. Through coordinated, complementary work with DOE’s other quantum research centers, the revitalized Q-NEXT will play an essential role in the national quantum ecosystem, according to Argonne Director Paul Kearns, who says quantum technologies are driving innovation across society.

The Renewed Mission: Harnessing Distributed Entanglement
The main goal of Q-NEXT is to seamlessly integrate quantum and conventional information systems across optical networks in order to unlock the future of quantum information. Now, the center will concentrate on showcasing distributed quantum entanglement. The phenomenon known as entanglement occurs when qubits, the basic building block of quantum information, stay connected despite being separated by great distances.
Q-NEXT The center is “building on the strong foundation laid over the past five years to take on a renewed mission, harnessing distributed entanglement to show what’s possible with scalable quantum platforms,” according to director and Argonne scientist Martin Holt. Incorporating quantum technologies into optical networks will “open the door for systems capable of revolutionizing how it processes, transmits, and receives information,” Holt continued.
“Quantum information science is a cornerstone of the nation’s technological future, with the potential to transform industries including computing, healthcare, and national security,” said David Awschalom, the founding director of Q-NEXT and current chief science officer, highlighting the field’s wide-ranging impact.
Three Core Scientific Goals
In order to expedite the creation of a quantum-connected world, Q-NEXT’s increased efforts are strategically concentrated on accomplishing three fundamental scientific objectives:
Communication: The center’s goal is to create reliable quantum communication networks that can connect gadgets in different cities. Demonstrating algorithms that can operate on several distant, networked quantum processors is a major goal.
Sensing: Quantum entanglement will be used by Q-NEXT to achieve previously unheard-of levels of precision in sensing applications. In addition to furthering fundamental scientific findings in quantum physics and gravitation, where entanglement provides a clear advantage in measurement, the research will show practical applications in domains like navigation and medicine.
Materials: New techniques for incorporating materials that can be scaled for industrial application will be the main focus of the effort. This necessitates addressing important issues related to combining various quantum material systems with sophisticated functionality and incorporating them into useful quantum devices.
Q-NEXT The overall goal is for quantum systems to function at the chip-to-chip, lab-to-lab, and city-to-city sizes, according to Deputy Director Jennifer Dionne.

Building on Foundational Achievements
In 2020, Q-NEXT was initially founded. The center accomplished a number of significant achievements in its first five years, including spearheading the construction of the Argonne and SLAC Quantum Foundries. A strong supply chain of standardized materials and equipment is greatly aided by these two national institutions.
One of its first scientific achievements was Q-NEXT, which achieved an amazing record lifetime of 5 seconds for a silicon carbide-based qubit. Additionally, researchers used niobium, a material that was previously understudied as a core quantum material, to create a high-performance qubit. A Roadmap for Quantum Interconnects, a paper co-authored by 39 experts from 15 organizations, was also released by Q-NEXT. It details the technological advancements required to disseminate quantum information in the next 10 to 15 years.
The center uses top-notch scientific facilities to carry out large-scale, team-based initiatives that integrate materials research, device engineering, and quantum physics theory. These facilities include the Centre for Nanoscale Materials (CNM), the Argonne Leadership Computing Facility (ALCF), and the Advanced Photon Source (APS) in Argonne.
Extensive Partnerships Accelerate Innovation
The two DOE national laboratories, eleven top universities, and six tech businesses make up the robust and dynamic network of partners that support the Q-NEXT center. The effort bridges the gap between scientific discovery and useful, real-world application through this cross-sector collaboration. Universities offer their knowledge of quantum communication and sensing, and industry partners give access to cutting-edge production facilities and prototypes.
Applied Materials, Caltech, Cornell University, IBM, Intel, IonQ, MIT, PsiQuantum, Quantum Opus, Stanford University, and the Universities of Chicago, California (Berkeley and Santa Barbara), Illinois Urbana-Champaign, Iowa, and Wisconsin Madison are among the important academic and business partners anticipated to join the partnership.
Industry partners like IBM see this partnership as essential to creating the computing of the future. According to IBM Research Director Jay Gambetta, Q-NEXT investigates the creation of effective quantum networks via optical lines that are connected to IBM’s quantum networking equipment. A future “quantum computing internet” might result from this basic technology, which might connect several interconnected fault-tolerant quantum computers spanning kilometers.
The partnership between SLAC and Stanford University, where scientists are creating a ground-breaking high-bandwidth quantum network, is a key component of the project. Regardless of the underlying technology, this network is specifically made to connect various quantum systems, such as atomic, superconducting, and solid-state qubits, to overcome obstacles.
Training the Quantum Workforce
Q-future is committed to developing the future generation of quantum scientists, engineers, technicians, and other professionals in addition to its research mandate. The center utilizes training opportunities, internships, and educational initiatives, including the Open Quantum Initiative Undergraduate Fellowship and the DOE Science Undergraduate Laboratory Internship. To maintain the United States’ leadership in quantum innovation, it must focus on developing a skilled workforce.
