Quantum Mechanics Primer: Fundamentals and Quantum Computing

1.1 Significance of Quantum Mechanics in Modern Science and Technology

Modern science and technology depends on the field of quantum mechanics. It allows us to understand phenomena that classical physics can't describe at the atomic and subatomic scales. This understanding is important for the development of many fields. Quantum computing, which uses quantum bits, or qubits, to carry out simultaneous computations and solve difficult problems more effectively than classical computers, has emerged as a game-changer.

With the help of quantum physics, data can be transmitted with previously unseen security. The creation of atomically precise materials and gadgets has been sparked by its uses in materials science. Modern science and technology depends on quantum mechanics since it drives fundamental research, produces ground-breaking findings, and changes technologies in a wide range of sectors.

1.2 Historical Background

The historical development of quantum mechanics has laid the foundation for numerous advancements in modern science and technology (Cárdenas-Martínez et al., 2018). In this article, we will explore the historical background of quantum mechanics and its significant contributions to the field of science and technology.

• a)

  Quantum mechanics originated in the late 19th century with Max Planck's work on black-body radiation, introducing the concept of quantized energy.

• b)

  Albert Einstein's explanation of the photoelectric effect in 1905, considering light as composed of discrete particles (photons), contributed to quantum theory.

• c)

  Niels Bohr proposed the Bohr model of the atom in 1913, incorporating quantum principles and explaining atomic spectra.

• d)

  Louis de Broglie's wave-particle duality concept in 1924 suggested that particles exhibit both wave-like and particle-like characteristics.

• e)

  Werner Heisenberg's uncertainty principle in 1927 highlighted the limitations in simultaneously measuring position and momentum with precision.

• f)

  Erwin Schrödinger's development of the Schrödinger equation in 1926 provided a mathematical framework for quantum systems and wave functions.
