Abstract—As we all know that the quantum cryptography is having lots of consideration in present time for security but it’s important to note that implementation of algorithms using QC is not viable if one wants to have the security intact. It can only be used to share keys using Quantum Key Distribution (QKD). Distribution of keys is just a part of securing information. Proper encryption and decryption are equally important for preventing Eve from guessing the key. But even QKD has a lot to overcome before it’s perfectly safe and practically useful. In this paper we are describing the various limitations of quantum cryptography along with its many real time implementation problems.
