Overview

• Scientists at Brookhaven National Laboratory discovered that coating tantalum with magnesium prevents oxidation and improves its superconducting performance.
• The magnesium layer acts as an effective oxygen barrier, enhancing tantalum's purity and raising its operational temperature.
• Advanced imaging and computational modeling reveal that magnesium's protection extends the coherence time of qubits by minimizing energy loss.
• The discovery could pave the way for more efficient and durable materials in the construction of quantum computers.
• Further research is needed to fully understand the implications of this material improvement on qubit performance.
