Quantum Computing met kerst

Christmas with Quantum Computers.
WHY QUANTUM NOISE IS NOT NOISE AT ALL.

Quantum computers are said to be build of q-bits. Instead of being able to be only in two states (zero and one), like normal bits in a conventional computer, they are supposed to be able to be in two states at the same time. The mixture of these two states can be considered a continuüm in between these two states. This is called superposition.

And such a q-bit is said to be able to entangle with another q-bit. So you have two or more q-bits in a state somewhere in between 0 and 1 being connected with each other in a manner that as you measure the states of the q-bits, you get a series of binary states that represent a common output of the entangled states.

The problem with quantum computers is that when doing the same operation multiple times, the quantum computer shows varying results. It is theorized that this is because of noise inside the quantum computer. This will flip the state of a q-bit into an undesired value at readout. Now all sorts of procedures have been invented to reduce this noise.

I propose that what is called noise is in fact just probability. It is inherent in the whole concept of quantum computing and cannot be reduced to zero. If we look at the concept of superposition more closely, we can see that we only have a possibility of a specific value (0 or 1) at readout; never a definite value. This means that eventual entanglement with other q-bits will have the same inherent probability. A quantum computer circuitry is therefore like a set of spinning dimes. It is not known on which side they will fall and they affect each other in an unpredictable manner.

If you now look at so called "quantum gates", the circuitry wherewith quantum computers are build, you will see that superposition of a q-bit's two states is not treated as a probability at all. And thus, all probability, or let us say "unpredictability" is interpreted as noise.

I conclude that noise in quantum computing is in fact just inherent unpredictability and i consequently predict that it cannot be reduced to a level that quantum computers become more efficiënt of more effective than classic computers.

That is, unless you want to believe in wormholes being modeled in quantum computers, or in multiverses being proven to exist with the help of quantum computers or any other of such fantasy-stuff.

Have a merry Christmas
