Quantum computing is a relatively young technology which has the potential to develop into the creation of super-powerful computers with super-fast problem-solving abilities. However, there are flaws in the technology which limit its abilities. One of the major flaws is that quantum communication can currently only be used on photon channels (like fiber optic cables) which limits the distance allowed by the communication. However, physicists believe that they have found a way to bypass this problem, expanding the potential for quantum communication. Their theoretical method combines a fiber optic cable with sending and receiving nodes and a bi-directional optical circulator to create a network that they believe will allow quantum communication to occur over long distances.
