Quantum information theory (QIT) is a young and actively developing area at the intersection of many research subjects, such as mathematics, physics, computer science, electrical engineering, biology, chemistry. The ultimate goal of QIT is to develop new technologies, in particular, the long-awaited quantum computer.
In some part of my research in QIT I use quantum phenomena called entanglement. Entanglement is heavily used in and relied on in QIT. It is found only in quantum systems, no classical system can exhibit entanglement. Entangled parties can be separated from each other over any distance, and they would always "feel" each other instantaneously without any communication between them. You might think that this would easily allow for faster-than-light communication (or even travel!), but no, no significant amount of information can be transmitted faster than light. But entangled parties can "feel" each other, and even change themselves depending on what's happening with another particle.
Don't be discouraged if you don't have a clue of what I'm talking about here. The man who helped discover entanglement, Einstein, went to his grave not understanding this phenomena and not even convinced in its existence.
