qubits

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.

The SQMS Center is working on reproducible and scalable realization of highly coherent superconducting qubits to open the way to more complex and scalable quantum computing operations. These capabilities could be used in Fermilab’s core particle physics research and fundamental physics more generally over time.

Fermilab is finalizing a partnership with Diraq and several universities for the Quandarum project. The project team intends to combine extreme environment electronics and silicon spin qubits to develop a quantum sensor that could profoundly impact the field of high-energy physics.

The Quantum Instrumentation Control Kit now features updated software and firmware and new companion hardware called QICK box. This Fermilab-developed system combines everything a scientist might need to conduct mind-bending research in a pizza-box-sized case.

Fermilab has twin laboratories that will probe superconducting qubits: QUIET is a new detector 100 meters underground and its counterpart is on the surface called LOUD, which began operations in 2022. The differences between the two detectors’ observations will allow researchers to assess how cosmic radiation affects qubit performance.

The new state-of-the-art QUIET laboratory will study the performance of qubits isolated from cosmic radiation. Its above ground counterpart is LOUD and together they will enable controlled experiments of quantum sensors.
