If that's  the way you saw that news I.e "Bitcoins will not be safe once we have powerful quantum computers", then regard it as a  clear FUD spread .. By then  Bitcoin would have found a way around it and   besides  not all Bitcoin,  just about 25%  which are addresses which already expose their public key.. Most of it will be related to P2PK address as they already  expose theirs when you send to it but for others it's  only when you spend out.. this is why avoidance address reusage  was hammered on  I.e if you eventually  spend from an address and you still receive on it later  you could be vulnerable if and only when QC can derive private keys to spend  coins from public keys, it's  not also good for privacy anyways (address re-use)!
