Squeezed light and application toward Quantum technology.

[@abhijeetjoshi9894]

I am a mechanical engineer and have worked as project engineer for 3 years and now I have started pursuing M.Sc(Physics) , I recently came across squeezed state of light and your video has helped me lot in visualising it!!! Keep uploading such videos!!!

I am new to this field and I have a v basic doubt....what happens to the output side after squeezing....I maybe wrong but what I know is that two photons are created from the vacuum state with the help of Squeezed operator(what it means physically I don't know...maybe some kind of non linear medium which produces two photons). And here comes my doubt(s) what are the relationship between states of two photons which were produced(I know that they are squeezed in one domain say amplitude squeezed) but how are they related to each other? And I don't understand the reason why we need to two photons in the first place, what is the argument behind?

[@saesunkim]

Good point. I am not entirely sure, but my guess is that people found that two photon operator do squeezing, so they are using two photon generation as squeezing operator. But if people find three photon generation or some strange one photon effect can also trigger squeezing, then there is nothing special about two photon generation.

Hi can I ask some doubts ?

[@saesunkim]

Feel free to ask!

Thank you!

9:53 we are squeezing the light in the phase space

[@saesunkim]

That is so cool! Are you using crystal?

[@hoseonglee3338]

Good! Good!
