Two questions about your question:

1) What do you mean by "advanced"?

2) What is your starting point, from which you want to know how far QM had advanced?

QM began in 1900, with Max Planck's observation that the spectrum of black body radiation could be explained with the mathematical assumption that light energy was quantized -- ie, that the energy in light at a specific frequency had a minimal amount. It made a major advance when, five years later, Einstein showed that this same assumption would explain the photo-electric effect. QM has advanced a GREAT DEAL since then, as you could imagine.

The most significant advance over the last few decades has been a theoretical framework called "The Standard Model," which blends QM with special relativity, and makes predictions that agree with experiment to TEN significant digits. Because of this agreement between theory and experiment, the Standard Model has been called the most accurate scientific theory ever.

The biggest event in QM over the last few decade or so has been observational evidence that pretty much refutes Local Hidden Variables.

Is quantum mechanics valid only for very small particles like atoms only?

Quantum Mechanics is valid for nearly everything (So far) it's just that the effects of it are only seen in microscopic scales like individual particles.


What is the significance of zero point energy in quantum mechanics?

AnswerZero-point energy (not to be confused with Vacuum Energy) is the lowest possible energy that a quantum mechanical physical system may have and is the energy of the ground state. This energy comes from the fact that after you remove all thermal and kinetic energy from an atom there is still quantum mechanical harmonic vibration that arises due to the Heisenberg Uncertainty Principle. This energy, so far, can not be taken away from a system.


Does the correspondence principle have application to macroscopic events in the everyday macroworld?

The correspondence principle has applications to macroscopic events in the everyday macro-world. This principle is a general rule not only good for science but for all good theory - even in areas as far removed from science as government, religion, and ethics. If a new theory is valid, it must account for the verified results of the old theory.


Why was heisenberg theory important?

It's important to physicists, because physicists want a consistent (without logical contradictions) understanding of how the universe works.As far as everyday practical applications, cosmology and quantum gravity will have little impact. Cosmology is the study of the large-scale structure of the universe, which we probably won't be physically exploring in our lifetimes, and quantum gravity is only relevant at energies so high that we will probably need to build machines exceeding the size of the Earth to make good use of it.


Why the rest mass of photon is zero in quantum mechanic?

I have a theory gw+l=gw l=m. If a gravitational warp traps photon then photon have mass. A small amount 0.000000000000000000000000001 mg. That is what i think. ============================================= Until such time as the previous contributor's hunch can be tested in the laboratory, all theory and experiment so far has shown the rest mass of the photon to be zero.

How do particles become entangled and what are the implications of this phenomenon in quantum mechanics?

Particles become entangled when their quantum states become interconnected, regardless of the distance between them. This phenomenon in quantum mechanics suggests that particles can instantaneously influence each other's states, even if they are far apart. This has implications for the concept of non-locality and challenges our understanding of cause and effect in the quantum world.


Is string theory the closest theory to a unified field theory?

Yes, so far it is- string theory explains many of the unresolved fundamental problems of our century, such as the opposition between Quantum Mechanics and Einstein's theory of general relativity.


How do you entangle particles in quantum mechanics?

In quantum mechanics, particles can be entangled by creating a special connection between them that allows their properties to be correlated, even when they are far apart. This entanglement is achieved through a process called quantum superposition, where particles exist in multiple states simultaneously. When the state of one particle is measured, it instantly affects the state of the other particle, regardless of the distance between them.


Why do electron contunuouslty move?

If you mean move around in "orbit" around the nucleus ...They don't. In quantum mechanics, forget everything you know from everyday experience about how objects behave, because quantum mechanics is WEIRD. One of my teachers once told me "nobody ever really understands quantum mechanics, they just get used to it." There's a fair amount of truth in that statement. Trying to picture it in your mind will only get you so far; at a certain point you just need to do the math and trust what it says even if it doesn't make any sense.


Who used quantum mechanics to describe the location of the electron?

Max Born was the first to note that the Schroendinger Equation (SE) -- ONE way to approach quantum mechanics -- could be used to accurately predict the PROBABILITY of an electron being at a specific location, given that the electron was in a specific energy field that was well-defined for all locations. For example, the SE for a single electron, in its lowest state around a positive nucleus, shows (after a LOT of math) that the electron is MOST likely at a distance of one Bohr Radius from that nucleus. Born was the first to note that quantum mechanics could never say EXACTLY where the electron was at any one time, but that it could very accurately determine the PROBABILITY that it was at a specified point. Very ironically, Schroendinger himself never really accepted Born's idea. Werner Heisenberg, Max Born, & Pascual Jordan developed an alternate approach to quantum mechanics that used operators and matrix mechanics to give eigenvalues for variables such as position. It was FAR more complicated than the SE, but also has more application. Heisenberg was soon able to show that the SE and the approach he & his colleagues developed were essentially the same.


Should I trust a mechanic hired by Wal-Mart?

Yes, mechanics hired by Walmart are trained in all of the things that they work on as far as cars are concerned. Even though some dont have degrees in the field they are very knowledgeable about the area in which they are working on. Of course! Even when hired by Walmart, mechanics must have training and knowledge in the field of mechanics. Walmart does set a standard on who they hire for specialty jobs such as a mechanic.


What follows the atoms around the orbit?

We need someone who understands the mechanics of subatomic particles better than I, but I don't think atoms normally orbit anything. Perhaps you mean electrons orbiting the nucleus. And again, as far as I remember nothing follows electrons in their orbit. We really need someone for this answer who knows a little quantum mechanics.
