Bitcoin & Google's Quantum Computer
According to Google's post, the quantum computer used had a 53-qubit processing power. This essentially means that it could hypothetically crack 53-bit encryption in a matter of seconds.

Hypothetically this could mean that Bitcoin's 256-bit encryption might be obsolete in a few years.

For the time being, Google's computer can only perform a single highly technical calculation at a time. In addition to that, quantum computers are still years away from being able to solve practical problems.

It does seem that in the years to come, Bitcoin and other cryptocurrencies will need a security upgrade or fork. If not, quantum computers could hypothetically be used to crack private keys to wallets. Old legacy wallets, such as Satoshi's cache of Bitcoin could be at risk.
