Answer 1

Hey mate here is ur query...

"""""""""""""""

the branch of physics concerned with quantum theory.

"quantum physics allows for particles to be in two states at the same time"


he word quantum refers to discreteness, i.e., the existence of individual "lumps" as opposed to a continuum. In Newtonian physics, all quantities are allowed to be continuous. For instance, particles can have any momentum and light can have any frequency. A quantum is a discrete packet of energy, charge, or any other quantity. For instance, one might say that electric charge is quantized in units of e=1.602e-19 C. 

Quantum physics is necessary to understand the properties of solids, atoms, nuclei, subnuclear particles and light. In order to understand these natural phenomena, quantum principles have required fundamental changes in how humans view nature. To many philosophers (Einstein included), the conflict between the fundamental probabilistic features of quantum mechanics and older assumptions about determinism provided a cognitive shock that was even more unsettling that the revised views of space and time brought by special relativity.

Answer 2

$\huge\mathbb{ANSWER--}$

#Quantum theory is the theoretical basis of modernphysics that explains the nature and behavior of matter and energy on the atomic and subatomic level. The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics andquantum mechanics.

#It results in what may appear to be some very strange conclusions about the physical world. At the scale of atoms and electrons, many of the equations of classical mechanics, which describe how things move at everyday sizes and speeds, cease to be useful. In classical mechanics, objects exist in a specific place at a specific time. However, in quantum mechanics, objects instead exist in a haze of probability; they have a certain chance of being at point A, another chance of being at point B and so on.

=>quantum mechanics :Quantum mechanics is the branch of physics relating to the very small.
