AB - <p>This thesis presents the experimental achievements of (1) generating entangled-microwave\&nbsp;<span style="line-height: 1.6em;">fields propagating on two physically separate transmission lines and (2) verifying the entangled\&nbsp;</span><span style="line-height: 1.6em;">states with efficient measurements. Shared entanglement between two parties is an essential resource\&nbsp;</span><span style="line-height: 1.6em;">for quantum information processing and quantum communication protocols. Experimentally,\&nbsp;</span><span style="line-height: 1.6em;">entangled pairs of electromagnetic fields can be realized by distributing a squeezed vacuum\&nbsp;</span><span style="line-height: 1.6em;">over two separated modes. As a result, entanglement is revealed by the strong cross-correlations\&nbsp;</span><span style="line-height: 1.6em;">between specic quadratures of the two modes. Although it is possible to verify the presence of\&nbsp;</span><span style="line-height: 1.6em;">entanglement with low-efficiency quadrature measurements, higher detection efficiencies are desired\&nbsp;</span><span style="line-height: 1.6em;">for performing protocols that exploit entanglement with high fidelity.\&nbsp;</span></p>
