DAY 1: Polarization of the Light

QUBITS: Quantum Computing :\ (nerdy huh?)


Keeping track of my progress...

One of the basic kinds qubits are displayed by polarizing photons. So, I just started off by making sure I remember the basic polarizing stuff(which I have had done with the last year)...



Do you remember the wave equations?...
Yes I do!... =] And most of the basic stuff on polarization.
Lemme just skip to the notes on Circular Polarization.

So, this kind of polarization, as is pretty obvious, occurs when two linearly polarized lights superposition themselves to form a waveform, where the angle keeps varying, making it look like, the Electric field vector pointing in circles. 


The directions pointer at the origin is the direction of the E Field at that very moment.

The elliptical polarization occurs when the amplitudes of the two super imposing waves are different, or the  phase lag is other than pi/2.

Most general case occurs when the amplitude, phase lag, and the frequency are all arbitrary. 
Up tomorrow: Polarization of photons
