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 …

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 …

We demonstrate an optical receiver that achieves the quantum Chernoff bound for
discriminating coherent states from thermal states in the multicopy scenario. In contrast, we …

It is well known that a minimum error quantum measurement for arbitrary binary optical
coherent states can be realized by a receiver that comprises interfering with a coherent …

We address the limit of the Gaussian operations and classical communication in the problem
of quantum state discrimination. We show that the optimal Gaussian strategy for the …

We consider the problem of distinguishing, with minimum probability of error, two optical
beam-splitter channels with unequal complex-valued reflectivities using general quantum …

Measurement of the state of a quantum system with inherent quantum uncertainty (noise)
approaching the ultimate physical limits is of both technological and fundamental interest …

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 …

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 …

We investigate the implementation of a measurement for binary optical coherent states that
minimizes the error probability with a fixed rate of an inconclusive result. As a special case …
