Summary

Story summary

The Princeton University team led by Andrew Houck and Nathalie de Leon developed a tantalum–silicon superconducting qubit with lifetimes over 1 millisecond.
The design uses tantalum to reduce energy loss and silicon substrates instead of sapphire.
The findings appear in Nature and address scaling and error correction.
The advance could boost quantum processors, potentially making them 1 billion times more effective in large systems.
