Itinerant Magnetism and Superconductivity in Exotic 2D Metals for Next-Generation Quantum Devices

The Quantum Systems Accelerator (QSA) pioneers studies to build and co-design the next generation of programmable quantum devices. An interdisciplinary team of scientists from QSA institutions, Lawrence Berkeley National Laboratory (Berkeley Lab), and the University of California, Berkeley (UC Berkeley), in collaboration with Los Alamos National Laboratory, conducted a series of experiments with a new type of layered 2D metal finding connections in electronic behavior that might potentially be useful for fabricating complex superconducting quantum processors.

How A Novel Radio Frequency Control System Enhances Quantum Computers

A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit controls at room temperature. They built a series of compact radio frequency (RF) modules that mix signals to improve the reliability of control systems for superconducting quantum processors. Their tests proved that using modular design methods reduces the cost and size of traditional RF control systems while still delivering superior or comparable performance levels to those commercially available.
