Optimal probes for continuous variable quantum illumination
Quantum illumination is the task of determining the presence of an object in a noisy environment. We determine the optimal continuous variable states for quantum illumination in the limit of zero object reflectivity. We prove that the optimal single mode state is a coherent state, while the optim...

| 總結: | Quantum illumination is the task of determining the presence of an object in
a noisy environment. We determine the optimal continuous variable states for
quantum illumination in the limit of zero object reflectivity. We prove that
the optimal single mode state is a coherent state, while the optimal two mode
state is the two-mode squeezed-vacuum state. We find that these probes are not
optimal at non-zero reflectivity, but remain near optimal. This demonstrates
the viability of the continuous variable platform for an experimentally
accessible, near optimal quantum illumination implementation. |
