rare earth ion-doped crystals
Diamond has very high Raman gain in optical phonon mode of 40 THz and has a wide transient window in a visible and near-infrared band, which makes it suitable for being an optical memory with a very wide band. After the Raman storage interaction, the optical phonon decays into a pair of photons through the channel, and the decay lifetime is 3.5 ps, which makes the diamond memory unsuitable for communication protocol. **problem is, it only lasts 10 seconds**
in a way, our perception of reality and predictions of the future is intimately tied to the memory we have
```A. If one of the paths is lengthened then
the interference can be altered to ensure that all
photons strike detector B.```
Why is this?
```On that
site, the basic interferometer is shown as in figure 1
and it is explained that interference between the
two paths ensures that the photon always strikes
detector A. ```
what gives rise to classical realism is the fact that quantum information leaks and smears out into the environment in a redundant way that's hard to eradicate. this gives rise to the classical consistency and behavior our intuition expects
@fuguer memory/habit
Why would changing the length of one of the routes change which detector it hits?
because changing the length of the routes affects the phase of the light
it means the photons from the two different paths are no longer exactly interchangable
thats a diagram of the quantum eraser
uses a beam splitter crystal (BBO) to split one photon into two entangled photons
Does the interaction make it a wave or something, why is that important that they interact?
then by inducing a different polarization on the left and right slits, you can tell if the polarization matches and which path the photon took
because particles interact with themselves
thats what we mean when we say quantum particles act like waves
a single photon interacts with other versions of itself and this is responsible for most of the fundamental properties of light such as least action principle, snells law, inertia, etc
did this shift from god to QM
I'm just trying to follow
Feynman explains this all in a way that will blow your mind if you watch his QED video series
REEEE
consider light reflecting off a mirror, ever wonder why it always reflects at angle of incidence?
No
because that's the shortest path, and if you consider the contribution of all other paths, they create destructive interference
@Wan6Saber she'd get over powered and defiled in war
the only path without interference is the shortest path
@Deleted User wrong
She'll only get defiled in bed <a:zoom:496262340258299904>
there and the kitchen
are where she belongs
not on a battle field
They won't listen
snells law, the formula for determining the angle that light is bent by lenses/water/materials... its simple the light is just always taking the shortest path
