Quantum computing is the use of quantum-mechanical phenomena (ie. superposition and entanglement) in order to compute a problem while a quantum computer is used to perform such computation.
The quantum computer follows the laws of quantum physics, which states that the ability to be in multiple states would result in enormous processing power, as well as performing tasks using all possible permutations simultaneously.
So the answer to the question is yes. Quantum computing’s system is based on cryptography in general, same as traditional banking. For now, Quantum computing does not exist, but in the foreseeable future, were it to be developed enough so as to potentially harm the Bitcoin system through hacking for example, the bitcoin protocol would be upgraded by using post-quantum algorithms that would counter any harm caused. By incorporating such algorithms, Bitcoin applications will result in a more secure and highly recommended system to be adopted.
