Before going to know about quantum computing, please know some basics about Quantum physics and biology
Here I am sharing the links to understand quantum physics.
Link1: Quantum physics
I hope the above link was helped to understand the confusion in physics
Link 2: Quantum biology
I think after seeing the above video you feel surprised. Now it's time to look into quantum computing
Link3: Quantum computing
Link4: Explain quantum programming
Link5: Have a glance on existing quantum computing.
Link6: Demonstration Quantum Supremacy
I think now you better understand the quantum computing. Yes, this computer is for future research development only not for personal use.
