- How does duality manifest in wave-particle duality in quantum physics? Discuss experiments like the photoelectric effect and their contributions.Describe the principles and potential applications of "quantum entanglement" in quantum communication channels.Describe the principles of "quantum entanglement" and its potential applications in quantum communication channels.
- What exactly is meant by the term "quantum tunnelling"?The treatment of electrons in atoms must be a quantum treatment, but classical physics still works for baseballs. Where is the dividing line? Suppose we consider a spherical virus, with a diameter of 30 nm, constrained to exist in a long, narrow cell of length 1.0 μm. If we treat the virus as a particle in a box, what is the lowest energy level? Is a quantum treatment necessary for the motion of the virus?Explain in great detail what real life applications and uses, quantum entanglement has.
- Small particles in the quantum world are... : actually particles, but look like waves actually waves, even though they look like particles are both waves and particles at the same time my brain hurts and I'm taking an L on this one. I'm out.Do you think it is reasonable to describe the Schrodinger equation as a postulate of quantum mechanics? What is a postulate?What is quantum electrodynamics (QED)?
- Richard Feynman, in his book The Character of Physical Law, states: “A philosopher once said, ‘It is necessary for the very existence of science that the same conditions always produce the same results.’ Well, they don’t!” Who was speaking of classical physics, and who was speaking of quantum physics?Imagine playing baseball in a universe (not ours!) where the Planck constant is 0.60 J s and thus quantum physics affects macroscopic objects. What would be the uncertainty in the position of a 0.50 kg baseball that is moving at 20 m/s along an axis if the uncertainty in the speed is 1.0 m/s?What difficulties does the uncertainty principle cause in trying to pick up an electron with a pair of forceps? Does the uncertainty principle apply to nature itself or only to the results of experiments? That is, is it the posi- tion and momentum that are really uncertain, or merely our knowledge of them? What is the difference between these two interpretations?
