Summary

Story summary

Princeton University engineers have developed a qubit that lasts more than 1 millisecond, tripling previous lab records.
The qubit uses a tantalum-silicon chip, improving durability and scalability for industrial use.
Replacing sapphire with silicon makes the design easier to mass-produce.
The findings address key challenges in error correction and scalability and move quantum computing closer to solving real-world problems.
The results were published in Nature.
