The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics).
Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler.
Physics students typically study regular quantum mechanics before moving on to quantum field theory.

Who has the greatest contribution in quantum mechanics among Heisenberg and Dirac and Schrodinger?
Heisenberg, Dirac and Schrodinger all made large combinations. Schrodinger is famous for his wave mechanics, Heisenberg for his matrix notation. Dirac realised that the theories of Heisenberg and Schrodinger were essentially the same. He also created the Dirac equation, an important step in the creation of a relativistic version of Quantum Mechanics.
What is true relativity or quantum mechanics?
Einstein's work on the Photoelectric effect, which won him the Nobel prize in 1921 was a bulwark of Quantum Mechanics. Einstein went off in another direction because of his inate suspicion that Quantum Mechanics has severe internal difficulties. Quantum Mechanics and Relativity have not yet been reconciled--but they are moving together slowly. Quantum Gravity seems to be key to the issue and may be resolved by String Theory.
When was Principles of Quantum Mechanics created?
Principles of Quantum Mechanics was created in 1930.
What is the definition of level shifting?
Level shifting is the slight deviation of the fine structure of the energy level of hydrogen-like atoms. This isÊfrom the predictions of relativistic quantum mechanics based on the Dirac equation.Ê
Is newton known for quantum mechanics?
The concepts of quantum mechanics were not explored until the 20th century. Newton only lived into the 18th century, so Newton did no work on quantum mechanics.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
Who created Quantum Mechanics and is it true that it is replacing the old physics?
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
Why quantum mechanics is someone called wave mechanics?
It is also called wave mechanics because quantum mechanics governed by Schrodinger's wave equation in it's wave-formulation.
What is the alternative to quantum mechanics?
Classical Mechanics and Wave Theory.
Is quantum mechanics a set of fields or is it just a lone branch of mechanics?
Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.
