Google recently unveiled Willow, its new 105-qubit quantum chip, capable of solving problems in less than five minutes that would take classical supercomputers billions of years.  This breakthrough is based on a significant reduction in error rates thanks to real-time correction strategies, marking a crucial step towards reliable quantum computers. 

Concerning data security, although quantum computers can potentially threaten current cryptography systems, post-quantum cryptography solutions are being developed to counter these risks. Google is actively participating in these efforts, including by adopting internal communication protocols that are resistant to quantum attacks. 

In addition, Willow’s computing power can be used to strengthen security by developing more robust cryptography algorithms, thus ensuring data protection in the quantum era.
