Researchers from the Fermilab-led SQMS Center identified material and fabrication features associated with variations in superconducting qubit performance. It is one of the most comprehensive studies ever conducted, linking materials and their structures to variations in quantum device performance.

Bosonic quantum error-correction devices at Fermilab’s SQMS Center use multiple quantum states within harmonic oscillators, a departure from traditional two-level qubit systems and a potential pathway to increased fault tolerance.

The SQMS Centre has achieved a significant advance in quantum search algorithms using qudit-based Grover search. This Grover search offers a solution to the limitations of traditional qubit systems, particularly as quantum computers scale beyond simple designs.

The Department of Energy has been supporting basic research in 1985 has set the foundation for today’s quantum technology.

In recognition of World Quantum Day, Fermilab’s Sara Sussman writes about the first benchmark from NEXUS qubit data. The new data has enabled the training of NVIDIA Ising Calibration, a vision language model for automating the calibration of quantum processors.

The NEXUS research team at Fermilab recently repeated the 2019 experiment after removing cosmic interference, find quantum information disturbed by other ways. This is the first time scientists have measured charge noise in a chip consisting of multiple qubits.

A partnership between the Quantum Science Center and the Quantum Systems Accelerator, two U.S. Department of Energy national quantum information science research centers, has enabled a breakthrough by Fermilab and MIT Lincoln Laboratory. Researchers used cryoelectronics to control ion traps, a key step toward realizing scalable quantum computers.

Fermilab’s Silvia Zorzetti is the principal investigator on a multi-year DOE Early Career Award focused on high-efficiency quantum transduction across microwave and optical domains to interface superconducting quantum computing with photonic networks.

A team of researchers, including scientists from SQMS and Fermilab, are investigating superconducting qubits to extend the computational power of quantum computers. This research could provide vital insights for designing more stable and powerful quantum processors.

A team of researchers at Fermilab titled, “Entangling remote superconducting qubits via transducer-generated multi-time-bin states”, demonstrates improved fidelity in both ideal transduction systems and those subject to noise, aiming to offer a potentially scalable architecture for future heterogeneous quantum networks.
