Advancing quantum information science
Fermilab leverages its world-class expertise in high-energy physics and advanced research facilities to pursue impactful quantum information science research and development.
Its scientists tackle problems in experimental and theoretical particle physics by taking advantage of fundamental quantum properties — such as coherence, superposition, entanglement and squeezing — and combine them with elements of information science to acquire, transmit and process information beyond what classical methods can achieve.
This research could lead to fundamental science discoveries, such as insights into dark matter — the mysterious substance scientists believe makes up much of the universe but has yet to be observed — and further understanding of how the universe works. It also has implications for national security, medicine and other fields.
In partnership with leading quantum information science researchers and institutions, Fermilab draws on its world-class knowledge in superconducting technology, electronics and controls systems, sensors, and theory and algorithms to advance high-energy physics, as well as quantum science and technology. In support of its science program, Fermilab actively participates in quantum information science initiatives across the entire U.S. Department of Energy Office of Science.
Research areas
Sensing and metrology
Scientists are using precisely controlled quantum systems to achieve greater sensitivity and resolution than traditional measurement approaches. These quantum sensors, overcome the effects of quantum fluctuations, allowing for precise measurements of fields, quantum phase shifts and highly precise ensembles of atomic clocks.
Fermilab scientists are conducting innovative research in sensing technology. For example, they are using qubits as sensors to search for dark matter particles, an approach that improves the signal-to-noise ratio and enhances the detection of dark matter candidates.
Communication and networking
Fermilab and its partners are striving to transmit quantum information across greater distances than previously achieved in laboratory settings. Their research could lead to a reliable, scalable and secure quantum network that could benefit national security, the energy delivery infrastructure, information security and many other areas.
They have demonstrated quantum teleportation and are building a metropolitan-scale quantum network in the Chicago metropolitan area. Eventually, they hope to realize a vision for a national quantum internet.
Computing and simulations
Scientists can manipulate information encoded in quantum states to solve hard problems and probe quantum phenomena. At Fermilab, researchers use quantum information to simulate complex quantum field theories, perform quantum machine learning, and execute optimization algorithms for Monte Carlo event generators, event reconstruction, data analysis and object classification.
Fermilab scientists develop algorithms to solve some of the biggest challenges in physics. They write programs that manipulate the quantum states of qubits. Unlike in classical computers, where answers show up on a computer screen, for quantum computing, scientists must measure the state of qubits and then interpret those measurements.
