Willow from Google and the crypto crash: what happened?

This week the cryptocurrency market was in a storm again, and one of the reasons was Google's unexpected announcement.

What's happened?
Google introduced its new quantum processor Willow, which made a breakthrough in quantum computing. As a result, Bitcoin dropped to $94.5k (-3.5%), ETH fell to $3.5k (-7.9%), SOL to $205 (-8.4%).  

What is Willow?  
Willow is the “brain” of a quantum computer. It uses the principles of quantum physics to process data. For example, Willow completed a calculation in 5 minutes that would take a classical computer longer than the existence of the Universe.
