Aluminum-based Low-Loss Interconnects for Superconducting Quantum Processors
Superconducting quantum processors are attracting significant interest due to their potential to perform complex computations at faster rates and with lower energy dissipation compared to conventional computers.
However, one of the major challenges in designing superconducting circuits is the high energy loss that occurs during signal transmission via interconnects, which leads to increased heat dissipation and limits the performance of the devices.
Recent studies have proposed aluminum-based low-loss interconnects as a solution to this problem. Aluminum has a superior conductivity compared to other metals used in interconnects, such as niobium, which results in lower energy loss during signal transmission.
Moreover, aluminum-based interconnects have been shown to have higher thermal stability, which helps in reducing heat dissipation and improves the reliability of the devices.
The use of aluminum-based interconnects has been demonstrated in a variety of superconducting quantum processors, such as transmon qubits, where they have shown significant improvements in terms of coherence times and error rates.
Overall, the use of aluminum-based low-loss interconnects is a promising solution to improve the performance and reliability of superconducting quantum processors, and further research in this area is expected to lead to even more significant advancements in the field of quantum computing.
