In theory, companies and organizations in the cryptocurrency and blockchain industry could acquire quantum computers, just as any other entity could.
However, quantum computers are currently in the early stages of development and are not yet widely available commercially. The ones that do exist are usually large, expensive and require specific conditions to operate, that's why only a few companies, research institutions and government own them.
Quantum computing has the potential to make certain types of computations much faster than is possible with classical computers, which could make certain cryptographic algorithms used in Bitcoin. It is possible that researchers are exploring the possibility of using quantum-resistant algorithms to secure Bitcoin transactions in the future.
