Untangling the mysteries of qubits by Roy van Rijn

How do quantum computers work? What is a qubit? What the hell happened to Schrödinger's cats? During this talk we'll together unravel the mysteries of entangled qubits. We'll explain the basics of quantum computing in simple and fun ways, including visual demonstrations with polarsation filters and a skippyball (known as Mr Qubit).

We'll even build an actual working quantum computer.... tribute, a simulator, in Java!

And I'll explain how larger quantum algorithms work by explaining the quantum benefits in Shor's Prime Factoring algorithm.

Super-presentatie! Ik begin qubits nu een klein beetje te begrijpen, en wat je er mee kan doen.

To put this simply the process of ‘quantum’ computing is a method of detecting the dielectric potential of the object being observed at a very specific time. For example instead of having bits of either 0 or 1 this process divides this into a scale. The scale may be out of 100 in which the number 40 is closer to 0 or an off bit.

When two objects are close together they share their dielectric potential which increases the difficulty in determining where on the scale both of the objects would be.

And of course when the two objects share their dielectric potential, as with all matter in the universe, there is great uncertainty of exactly where the dielectric is spread out amongst its combined self.

What is clear is that coherent energy, or matter, is a self contained stable magnet. What is happening in the process of ‘quantum’ computing is the changing of the coherent matters magnetic stability by adding energy.

Adding energy changes the dielectric potential which is shared by all other ‘quantum’ bits.

So now the quantum bits share a slightly elevated energy state. But because of the natural stable magnetic properties of each ‘quantum’ bit there is an interplay of expanding magnetic fields which shifts the dielectric, or added energy, to someplace else. In this instance to a region of lesser dielectric.

A direct comparison are waves on the ocean. There are waves coming from all over going this way and that, up and down, to the left or right and all exchanging a little bit of their energy to everything around it. It never stops moving and this is what the dielectric is doing.

When a measurement is made to determine the state of the bit, the very act of measuring requires a removal of a small amount of dielectric. Therefore that measurement acts as a reset to the quantum bits to their natural resting state.

So when you go out and look at the ocean try to think how easy it would be to go measure a wave in amongst all the other waves, when all the other waves are moving and changing that wave you want to measure.


Quantum is just another word for the study of the properties of coherent matter.

Once that connection is realized the process of advancing our understanding of the universe will take a giant leap forward.

Food for thought.

The multiple universe interpretation explains, quite rationally, how spooky action works. Its nothing magical or spooky.
