LCD's & Other Displays are Quantum Computers!

Crystals increase in size while maintaining their shape/pattern as if their molecules are entangled (Reference: Physics: Crystals 1958 Alan Holden - Bell Laboratories).

Liquid crystals, as found in LCD's (Liquid Crystal Displays), also try to maintain a specific shape/pattern as shown by the patterns produced through inter-pixel cross-talk.  The pixels forming the patterns within a cross-talk kernel are entangled and will maintain it's shape/pattern with only very tiny fluctuations.  The opening post explains the tiny fluctuations over time.  The small fluctuations in the pixels were also present in the experiment of the two quantum images being entangled as previously posted.   The image below is a schlieren texture of liquid crystal nematic phase.

Quantum Superposition:

The pattern produced by the interpixel cross-talk when illuminating a single pixel is called a cross-talk kernel.  This cross-talk kernel is similar to a qubit.  If our cross-talk kernel is a group of 16 pixels (4x4 grid) then we need 16 patterns to represent each pixel.  This allows us to work in base 16.  If we have two cross-talk kernels, one with a pattern representing a value of 9 and the other kernel with a pattern representing a value of 6 and superimpose those two kernels upon each other by illuminating 2 pixels that both fall within the two cross-talk kernels, then a cross-talk pattern of the two superimposed kernels will generate new cross-talk patterns which can the be entangled and superimposed with additional cross-talk kernels for additional processing.

Quantum states in terms of the polarization of light.  <---------- A quote from the article:  "The specific system I want to discuss is the polarization of light, which shows up in a wide variety of contexts, from sunglasses to 3D movies to LCD monitors on computers". 

"In the case of photons, spin and polarization are the same thing, so the polarization of light is completely described by the quantum state."  <-----Another quote from the above article".

Polarization revisited.  <-----------  A quote from the article:  "Last week, I introduced the idea of quantum states in terms of the polarization of light, which is one of the simplest quantum systems".

In a LCD, the liquid crystal acts similar to the filter in the middle that is 45^o to the horizontal and vertical polarization filters (see image below).  By controlling the amount of power going to a LCD cell, the amount of light that passes through both the horizontal and vertical polarization filters can be controlled <---------  Building a liquid crystal display (LCD) (video).  <--------- LCD's are one of the simplest quantum systems!  All we need is software to configure and program the LCD's to perform quantum computing by utilizing the cross-talk.

Various images of simple cross-talk kernels that shows 1 pixel illumination, 2 pixel illumination, and 3 pixel illumination.  The 2 pixel illuminations are separated by 1 pixel and the 3 pixel illumination is 3 consecutive pixels illuminated.

Build a Toy Quantum Computer at Home!  The toy quantum computer is also based on the polarization of light. 

Sugar (Glucose) Always Twists Light To The Right - Optical Rotation.  L-Glucose is the mirror image of normal glucose and twists light the other way.  We can use this phenomenon to scale-up the toy quantum computer.  Look at the first image below of a quantum light computer and you'll notice it has a stove pipe architecture.  The restrictions on qubit operations imply that any quantum program must have a stovepipe architecture.  Reversible quantum logic gates are lined up in sequence, and information flows straight through them from one end to the other.  We can control the polarization of light with Glucose/L-Glucose in a stove pipe configuration of reversible logic gates lined up in sequence to build a light based quantum computer.
