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.

Unimon: A New Qubit to Boost Quantum Computers for Useful Applications

A group of scientists from IQM Quantum Computers, Aalto University, and VTT Technical Research Centre of Finland have discovered a new superconducting qubit, the unimon, to increase the accuracy of quantum computations. The team has achieved the first quantum logic gates with unimons at 99.9% fidelity — a major milestone on the quest to build commercially useful quantum computers.
