Quantum theory restricts our ability to determine the state of a physical system. This is true even if we know for certain that it was prepared in one of a known set of possible states. I describe two types of optimal strategy for state discrimination. These are (i) state discrimination with minimum
## Abstract Unambiguous discrimination among nonorthogonal but linearly independent quantum states is possible with a certain probability of success. Here, we consider a new variant of that problem. Instead of discriminating among all of the __N__ different states, we now ask for less. We want to u
