I was reading a news article saying that bitcoins will not be safe once we have powerful quantum computers. Is there a good alternative way to store bitcoins safely in such a situation ?

Let's imagine that we are criminals (in fact, honest people) and have access to the latest quantum computers capable of cracking modern encryption systems. Is it advisable for us (having such quantum computers) to hack bitcoin wallets of ordinary network users? At the same time, we even know in advance whether a specific bitcoin wallet contains satoshi for a large sum of money or not. Of course not! It is much more promising to hack the computer system of some large corporation that conducts an audit and inventory of its settlements once a quarter. During this time, many fictitious payments can be created in the corporation's accounting system, which will allow very large sums of money to be quietly stolen. This is exactly what real criminals do, there have been such examples in history 👮

For real criminals who have received a super-effective tool for cracking codes, Bitcoin is far from the most interesting object for attack🦖

For example, if such quantum computers fall into the hands of state intelligence agencies (and this is most likely what will happen in practice), then their main interest will not be in Bitcoin, but in the military and industrial secrets of other states🥥

It is also necessary to take into account that the Bitcoin developers know perfectly well how to protect the network of the first cryptocurrency from such attacks. And if they have not yet changed the Bitcoin code, have not made the appropriate changes, it is only because these threats are currently potential, not real.💻

That is why it is very important to our for us to store our Bitcoin phrase properly without the knowledge of anyone because it can easily falsify your signature, the attacker can successfully steal your Bitcoin if the public keys exposed, they derived private keys from that exposed public keys by using a quantum computer without your permission .
Bitcoin is a Blockchain based system that validate transactions and secures our wallet because it rely on cryptographic algorithm with give quantum computers an edge to break through by allowing attackers to take over your asset.

The developers of Bitcoin will not allow this to happen and so they must be working to create a solution or prevention from allowing these from happening.
