The Helstrom measurement: A nondestructive implementation
Rui Han, Gerd Leuchs, János A. Bergou
We discuss a novel implementation of the minimum error state discrimination measurement, originally introduced by Helstrom. In this implementation, instead of performing the optima…

Residual and Destroyed Accessible Information after Measurements
Rui Han, Gerd Leuchs, Markus Grassl
When quantum states are used to send classical information, the receiver performs a measurement on the signal states. The amount of information extracted is often not optimal due t…

Near optimal discrimination of binary coherent signals via atom-light interaction
Rui Han, János A. Bergou, Gerd Leuchs
We study the discrimination of weak coherent states of light with significant overlaps by nondestructive measurements on the light states through measuring atomic states that are e…
