It is not as easy as people think. Proof-of-work isn't as vulnerable to “quantum speedup” as people think, and the signature can be replaced with something more quantum-resistant before the day of reckoning.

Quantum computers were first being thought by the CIA and now Google and IBM are also racing and competing to release a quantum computer. Quantum computers are supercomputers and can solve algorithms a thousand times faster than normal computers. But let us say that if the masses are now using quantum computers will it be the end of bitcoin, the answer is not. If the technology is improving cyber security is also improving and that is why our bitcoins are still protected when the time comes.

if the quantum computer is mass-produced , ordinary people can use it to calculate the private key of all bitcoin wallets and take away the bitcoin inside . bitcoin encryption algorithms need innovation . quantum computer mass production takes about 3 years .
this is possible . Satoshi may not have considered this issue . now you can buy a quantum computer and steal all bitcoins . a valuable finder . unfortunately , i did not merit

Not going to happen.
Those quantum computers will be expensive when released (a few years from now), not available for common people.
And when these computers are being adopted, signing schemes and cryptography are going to be improved as well.
