Before going through this project I would suggest to read the first part of this series here :
I have made a basic circuit of 1-bit RAM using Quantum gates. The input A acts as the S of a SR flip flop . Input B is the write enable line. The Input R is the read enable line. When the write enable line is enabled then we can write the input. When we activate the read enable line ; we can read the written input. Now this data can be transmitted by quantum teleportation to another RAM location instantaneously.
You can see the output on the extreme left bottom before the rectangular cross-sheet. It is now off as neither the read enable nor the write enable lines are activated.
Now in this above diagram the write enable line is activated so the input is stored ; but when we can see a superposition on the write enable output line as I have placed a Hadamard gate ; as it is exclusively the job of the Read enable line to give us the value stored.
Now as you can see ; since the read enable line is activated ; we can see the output----- which is 1. Thus we have made a 1-bit RAM using Qubits. Disclaimer - This circuit works 100 percent accurate with up and down Qubits only ; for random superpositions ; the results are not always accurate. Currently working on that part.
Now we can transport this information to another RAM unit using quantum teleportation---------- A modification of data bus ; which I will speak about in much more details in the next part. I will discuss how to make a quantum data bus using quantum entanglement and quantum teleportation.
This is the circuit of quantum teleportation. Check out the simulation of my Quantum teleportation model here :Qubit generation using spins of electron :
We can make Spin Qubits using the procedure of Stern-Gerlach experiment.
As the bombarding of the number of electrons with superimposed spin ( +x spin ) increases ; there is a 50 -50 probability of up spin and down spin. The up spins are deflected towards the positive polarity and the down spins are deflected towards the negative polarity. We can treat these spins as Qubits. Thus we can easily generate Qubits using electron spins. You can get a visual idea from here :Qubit generation using gravitons :
Now let's come to the graviton part. While studying string theory I was fascinated by the particle graviton. Well ; in traditional quantum computing ; the polarization of photons are used as Qubits. An interesting fact is that a graviton is actually two photons spinning in the same direction. Thus it carries more information than a photon. That is 4^N Bits of information for just N Gravitons.
The above picture is an extract of a paper from Cornell University which emphasizes on how to prepare gravitons easily from two photons.
If we consider photon ; it is passed through a specific crystal ; which splits it up into two polarizations ; we may consider horizontal and vertical polarizations as two of our Qubits. Any random polarization is merely the superposition of the horizontal and the vertical ones. Similarly we can use Gravitons for generation of Qubits. I will talk about this topic on graviton and how parallel universes are revealed by quantum entanglement ; in the later parts of this series. Hope you are enjoying this series of Digital TENET.Thank you
