AUTOMATIC SCANNING OF INTERFERENCE PATTERNS
Accurately measuring interference patterns from projections on a screen is rather tedious. However, you can build a simple device that makes it possible to display interference patterns on an oscilloscope, making it easy to measure not only the distance between fringes, but also their amplitude. As shown in Figure 5, the idea is to use a…

YOUNG’S INTERFERENCE OF LIGHT
Around 1801, Thomas Young discovered interference of light. This phenomenon is only possible with waves, providing conclusive evidence that light is a wave. In Young’s experiments, light sent through two separate slits results in a pattern that is very similar to the one produced by the interference of water waves shown in Figure 2. Figure 2 Water…

NEWTON’S VIEW: LIGHT CONSISTS OF PARTICLES
In 1704, Sir Isaac Newton proposed that light consists of little particles of mass. In his view, this could explain reflection, because an elastic, frictionless ball bounces off a smooth surface just like light bounces off a mirror—that is, the angle of incidence equals the angle of reflection. Remember that Newton was very interested in…

What is a qubit and its properties?
Qubits are represented by a superposition of multiple possible states. A qubit uses the quantum mechanical phenomena of superposition to achieve a linear combination of two states. A classical binary bit can only represent a single binary value, such as 0 or 1, meaning that it can only be in one of two possible states.

What are the three pillars of quantum mechanics?
The framework of quantum mechanics rests on three pillars: the Hilbert space of quantum states; the Hermitian operators, also called observables; and the unitary evolution operators.

Who is the father of quantum mechanics?
Niels Bohr and Max Planck, two of the founding fathers of Quantum Theory, each received a Nobel Prize in Physics for their work on quanta. Einstein is considered the third founder of Quantum Theory because he described light as quanta in his theory of the Photoelectric Effect, for which he won the 1921 Nobel Prize.

What are the four pillars of quantum mechanics?
Pillars of quantum mechanics are 1) Classical mechanics, 2) Electromagnetism, 3) Special relativity , 4) Relevant Mathematics and 5) Mindset to dispense with common sense and flexibility to accept unintuitive theoretical results if they conform to experiments!

What are the two golden rules of quantum mechanics?
Fermi’s First Golden Rule is the result of applying second-order time-dependent perturbation theory to quantum scattering and resonances. Fermi’s Second Golden Rule is the result of applying second-order time-dependent perturbation theory to absorption.
