Q-NEXT

---

Q-NEXT is a U.S. Department of Energy National Quantum Information Science Research Center whose mission is to develop the science and technology to control and distribute quantum information. Established in 2020 and led by Argonne National Laboratory, the Q-NEXT organization includes national laboratories, universities, and U.S. quantum technology companies:. It is one of five National Quantum Information Science Research Centers funded by the Department of Energy.

Research

As part of its mission to deliver technologies for reliably controlling and distributing quantum information, Q-NEXT advances the development of “quantum interconnects,” devices that enable the transfer of quantum information between two different physical media. To build these devices, Q-NEXT focuses on three core quantum technologies:

• Quantum communication. Q-NEXT is developing technologies to enable the secure communication of quantum information over long distances, enabling the establishment of “unhackable” information networks.
• Quantum sensors. Q-NEXT is advancing quantum sensor technology to achieve previously unreachable sensitivities, enabling new applications in physics, materials science, and life science.
• Quantum simulations. Q-NEXT is building testbeds for quantum simulators and future quantum computers. These will enable applications in cryptanalysis and logistics optimization.

Q-NEXT is also creating a "technology roadmap" that outlines the research and scientific discoveries needed for the distribution of quantum entanglement, especially for impactful progress in quantum computing, communications and sensing technology, on a 10- to 15-year timescale. The document will guide Q-NEXT R&D and help inform the growth of a national quantum ecosystem.

Facilities and resources

Q-NEXT collaborating institutions are building two national foundries to provide materials for quantum technologies. One, based at Argonne National Laboratory, will focus on solid-state quantum devices. The SLAC Detector Microfabrication Facility, based at SLAC National Accelerator Laboratory, will focus on superconducting devices. These foundries will serve as a national resource to provide new sources and a robust supply chain of high-quality, standardized materials and devices that will support both known and yet-to-be-discovered quantum-enabled applications.

Q-NEXT also plans to establish the first National Quantum Devices Database for the standardization of next-generation quantum devices, helping to promote their development and fabrication.

The Q-NEXT center provides access to science facilities through its university and national laboratory partners. Among them are Argonne’s Advanced Photon Source, Argonne’s Center for Nanoscale Materials, the Argonne Leadership Computing Facility and SLAC’s Linac Coherent Light Source and Stanford Synchrotron Radiation Lightsource. Q-NEXT scientists will also use a 52-mile quantum loop at Argonne — a fiber-optic testbed — for quantum communication research.

Using these and other capabilities, Q-NEXT researchers will demonstrate secure communication links, networks of sensors, and simulation and network testbeds.

Workforce development in quantum information science

Through its industry and academic partner institutions, Q-NEXT aims to train the quantum information science workforce by creating new programs that take advantage of the breadth of these partnerships and gives students the opportunity to learn in an environment that combines national lab, academic and industry researchers.

Partners

The Q-NEXT collaboration partners include the DOE national laboratories, academic institutions, and leading industries.

The partner national laboratories are Argonne National Laboratory, Pacific Northwest National Laboratory and SLAC National Accelerator Laboratory.
