Quantum computing explained

at different levels


Not very many decades back the mother board of a GSM mobile telephone filled an entire room.

Seems like the cooling part is one of huge impeding factor in scalling this thing in size. This thing is just so huge.
What sort of a coolant are they using here, is it the conventional reon.
For avoidance of corrosiveness and other environmental factors, why not apply cyrogetics with a cascade coolant (refrigirant) like the ones used in LNG technology using methane, propane, & ethylene?

Cyrogetic temperature are tempratures that do not occur naturally, they have to be simulated.

I have tried to look for someone on the internet who can explain the dead ends in quantum physics and I never got to it. They all say that there is some missing information. for example the particle nature of matter and the wave nature of matter seem to be both correct, which is a conflict. in some instances, some “particles” behave like waves. secondly, there is the problem of matter at the speed of light vs time.

Most quantum physicists will talk about observations and will avoid talking about the “mechanism”. for example, time space continuum is a mathematical observation that has no logical explanation of the mechanism by which it comes into effect. quantum phsyics is still unknown in my opinion. Its probably the universally correct approach to physics that we are yet to discover since newtonian physics is only true withing a narrow scale and fails when stretched a little bit. once we master quantum physics, newtonian physics will be obsolete.

The major problem is coherence. It’s almost impossible to do any data experiment without interference from the external environment which in turn changes the results. Think of killing Schrodinger’s cat once you open the box.

Relations and scaling.
Quantum mechanics in the broad sense is not a single theory, but a class of theories that operate on different length and energy scales. These theories are in a hierarchy, where the characteristics of a theory can be derived from an underlying theory. The most fundamental theory that exists today, the standard model, describes elementary particles, such as electrons and quarks, but even this theory is believed to have theories below it. String theories and other multidimensional theories have long been candidates, but they still lack experimental support.

All systems under 10 nm must usually be quantum mechanically, but the length scale depends on temperature, and down to the absolute zero point, quantum effects are important, even on large systems. This is called macroscopic quantum systems, such as the quantum hall system. Superconductivity, superfluidity and Bose-Einstein condensation also come under macroscopic quantum systems.
