Our hard drives are reaching the limit of memory capacity and they are studying about the idea of using the molecules and atoms to store memories. Can information or memories be stored in the quantum state? When we heard of quantum state applications in computer, we mostly think about quantum computers.. but how about purely using the quantum state as memory and information storage. There should be studies about this.. can you share some references if you have come across them as well as its plausibility based on your own knowledge. Thanks.
