LCD's & Other Displays are Quantum Computers!
« on: July 23, 2017, 09:16:59 AM »
LCD's and other displays are Quantum Computers waiting to be configured and programmed!  This is not a joke!  Software for testing is being written as we speak!

I was researching liquid crystals in my search for a memristor.  It does appear liquid crystals have properties of a memristor.  Stuck or frozen pixels suggests a memory effect.  The polarity to the LCD cell reverses when displaying the next frame to avoid stuck pixels.  This is mind-blowing!  This means that every pixel on a LCD screen can be configured as an individual memristor.  The value (intensity) of a pixel not changing over time will be held near a constant value (intensity) by the LCD with very small fluctuations in it's value, thus allowing us to use the pixels as memristors for both memory and processing.  This is awesome in and of itself.  However, there is a serious problem in having all of these individual memristors inside the LCD to be disconnected from each other.  How can data be stored, processed, and retrieved when the individual memristors can't form logic gates or other circuits.

Compare the two patterns as found in the cross-talk kernel in figure 13 of the Interpixel cross-talk publication (figure 13 shown below).  The two patterns are near mirror images of each other.  The cross-talk kernel is holding two patterns entangled with each other.  Compare the mirrored patterns of the cross-talk kernel (figure 13) with the two quantum images entangled with each other as published by researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland.

The pixels contained within a cross-talk kernel becomes entangled via Interpixel Cross-talk!

As a quick side note:  LCD's can also be made bidirectional where the LCD alternates between being a camera on even frames and a display on odd frames ( BiDi Screen from MIT Media Lab -Bidirectional Screen)

Here's an excellent publication on cross-talk:  Color filter array patterns for small-pixel image sensors with substantial cross talk.

Figure 4 below, taken from the above publication, shows a visual illustration of cross-talk.

Quantum Entanglement (QE) as viewed by a computer programmer:

QE isn't much different than having many objects or labels point to the same memory address.  For example,  let's say we have red, blue, and green all pointing to the same memory address (0xEF) and this memory address (0xEF) holds the value of 9.  So, red = 9, blue = 9, green = 9.  Now, if we assign blue a value of 6, then red and green will also have the value of 6.  The three colors pointing to the same memory address of (0xEF) are as if they are entangled.  Change one color and the other two colors will change to the new value.  Below is a small code snippet which demystifies how to handle and process QE pixels.  The image below are the results of the print statements in the code snippet.  Note:  a, b, and c could also represent red, blue, and green.

e = [7]
a=b=c=[0,3,5]
a[0]=e
b[1]=0
print(a)
print(b)
print(c)
e[0] = 8
print(a)
print(b)
print(c)

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 45o 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.

A quantum memristor is a passive resistive circuit element with memory, engineered in a given quantum platform.  A memristor can be implemented in quantum optics by means of a beam splitter with a tunable reflectivity.  This paper on a quantum memristor shows that a similar implementation can be achieved with frequency-entangled optical fields and a frequency mixer that, working similarly to a beam splitter, produces state superpositions.
