We investigate quantum measurement strategies capable of discriminating two coherent
states probabilistically with significantly smaller error probabilities than can be obtained …

The discrimination of non-orthogonal quantum states with reduced or without errors is a
fundamental task in quantum measurement theory. In this work, we investigate a quantum …

The optimal discrimination of nonorthogonal quantum states with minimum error probability
is a fundamental task in quantum measurement theory as well as an important primitive in …

Quantum state discrimination is a central problem in quantum measurement theory, with
applications spanning from quantum communication to computation. Typical measurement …

The discrimination of two nonorthogonal states is a fundamental element for secure and
efficient communication. Quantum measurements of nonorthogonal coherent states can …

We derive the quantum limit on the error probability exponent for discriminating any M
multimode coherent states of light and show that it is four times that of an ideal heterodyne …

We address the long-standing problem of discriminating coherent states with the minimum
error rate. We show an optimum receiver for coherent states which admits a relatively simple …

Generalized quantum measurements implemented to allow for measurement outcomes
termed inconclusive can perform perfect discrimination of non-orthogonal states, a task …

We consider the problem of discriminating quantum states, where the task is to distinguish
two different quantum states with a complete classical knowledge about them, and the …

We study the problem of determining the photon number statistics of an unknown quantum
state using conjugate optical homodyne detection. We quantify the information gain in a …
