**15 jun 2012, 13:26****Chapter 5**main question

“can you please explain to me ...” (he started almost every question with that )

-why R.T* + T.R* = 0

-what is h(z,t)

-what distribution is there in each port when you do “photon number state splitting”

-the connection with the balls and the two boxes

-what is the distribution in each of the ports of “coherent state splitting” and what is the mean

-what is detected and how in de the homodyne detection

-why would we want to know the quadrature fluctuations in homodyne detection

-what would happen is we put a coherent state at the input of the mach zehnder interferometer in stead of a single photon.

-what happen if i send a single photon plane wave to a double young slit

-in the franson interferometer is the state bunched or anti-bunched

-why do we make the time discrete?

-what is the physical case of 1/4*delta_(j-n)k

-how can you explain that by changing phi1 you can manipulated gamma_2 when it doesn’t even pass there.

Part 2 of the exam:

-explain the purcell effect

-why is f smaller than 1 and larger than 0

-what is gamma_e->g

-what is the purcell factor

-what is Q in the purcell factor

-on what does Delta_omega_c depend

-is the equation on slide 249 always valid (the lowest)

-explain in large steps how we found the top equation on slide 249

-what is v²(w_eg, r0) on slide 247

-why can do we only work with d//eg (slide 248)

-explain how we derived the einstein A coefficient, what does it mean, ... (in detail about the formulas, what all factors mean etc.) what is sigma, does it also contain omega, why summation, why integral, ... etc.

-what is a coherent state? when is a state coherent?
