qubits

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.

Through unique qubit fabrication techniques, scientists have demonstrated systematic improvements in the performance of superconducting devices for quantum computing, communication, and sensing.

From Phys.org, July 5, 2023: Researchers from Ames Laboratory announced important research results done with Fermilab’s SQMS Center that will improve the quantum circuit quality of a vital qubit component. The research was an important step in quantum computing development and proves that collaborative research groups like SQMS with Ames can lead to solving very complex technological and scientific problems.

SQMS Center researchers have identified a new contribution to a qubit’s performance by probing and simulating several-atom-thick layers called silicides.

From Nasdaq, Dec. 15, 2022: Quantum computing can perform calculations in ways that are impossible for classical computers. It was recently announced that Google’s Sycamore quantum processor was used by researchers from Caltech, Google, Fermilab, MIT and Harvard to generate and control what is equivalent to an Einstein-Rosen bridge, or more commonly referred to as a wormhole.

To cool quantum computing components, researchers use machines called dilution refrigerators. Researchers and engineers from the SQMS Center are building Colossus, the largest, most powerful refrigerator at millikelvin temperatures ever made. The new machine will enable new physics and quantum computing experiments.
