Unraveling a quantum puzzle: how tantalum improves qubit performance

Quantum processor technology

Scientists have found that tantalum, a superconducting metal, significantly improves the performance of qubits in quantum computers. Using X-ray photoelectron spectroscopy, they found that the tantalum oxide layer on the qubits was not uniform, prompting further investigations into how to modify these interfaces to improve overall device performance. Researchers decode the chemical profile of surface … Read more
