Displacement of propagating squeezed microwave states
Physical review letters, 2016•APS
Displacement of propagating quantum states of light is a fundamental operation for quantum
communication. It enables fundamental studies on macroscopic quantum coherence and
plays an important role in quantum teleportation protocols with continuous variables. In our
experiments, we have successfully implemented this operation for propagating squeezed
microwave states. We demonstrate that, even for strong displacement amplitudes, there is
no degradation of the squeezing level in the reconstructed quantum states. Furthermore, we …

Displacement of propagating quantum states of light is a fundamental operation for quantum communication. It enables fundamental studies on macroscopic quantum coherence and plays an important role in quantum teleportation protocols with continuous variables. In our experiments, we have successfully implemented this operation for propagating squeezed microwave states. We demonstrate that, even for strong displacement amplitudes, there is no degradation of the squeezing level in the reconstructed quantum states. Furthermore, we confirm that path entanglement generated by using displaced squeezed states remains constant over a wide range of the displacement power.
