Effect of Losses <strong>on</strong> Squeezed Light<br />

Model of losses in quantum optics<br />

Intensity loss : 1-<br />

Can be modelled by a beam<br />

splitter with reflectivity R=1<strong>and</strong><br />

transmitivity T= .<br />

Vacuum fluctuati<strong>on</strong>s are<br />

entering by the empty port.<br />

What is<br />

the noise<br />

after the<br />

loss?
