Unambiguous Discrimination Between Linearly-Independent Quantum States
The theory of generalised measurements is used to examine the problem of discriminating unambiguously between non-orthogonal pure quantum states. Measurements of this type never give erroneous results, although, in general, there will be a non-zero probability of a result being inconclusive. It is shown that only linearly-independent states can be unambiguously discriminated. In addition to exa...
متن کاملOptimum unambiguous discrimination of two mixed quantum states
We investigate generalized measurements, based on positive-operator-valued measures, and von Neumann measurements for the unambiguous discrimination of two mixed quantum states that occur with given prior probabilities. In particular, we derive the conditions under which the failure probability of the measurement can reach its absolute lower bound, proportional to the fidelity of the states. Th...
متن کاملStructural approach to unambiguous discrimination of two mixed quantum states
We analyze the optimal unambiguous discrimination of two arbitrary mixed quantum states. We show that the optimal measurement is unique and we present this optimal measurement for the case where the rank of the density operator of one of the states is at most 2 (“solution in 4 dimensions”). The solution is illustrated by some examples. The optimality conditions proved by Eldar et al. [Phys. Rev...
متن کاملOptimal Unambiguous Discrimination of Quantum States
Unambiguously distinguishing between nonorthogonal but linearly independent quantum states is a challenging problem in quantum information processing. In this work, an exact analytic solution to an optimum measurement problem involving an arbitrary number of pure linearly independent quantum states is presented. To this end, the relevant semi-definite programming task is reduced to a linear pro...
متن کاملUnambiguous discrimination of mixed quantum states
Quantum state discrimination is an essential problem in quantum information theory. It was first considered for pure states in the literature. One strategy of quantum state discrimination is that one is asked to distinguish the given states without error, but a non-zero probability of inconclusive answer is allowed. Such a strategy is called unambiguous discrimination. Unambiguous discriminatio...
